Trends in Alternative Medicine Use in the United States, 1990-1997: Results of a Follow-up National Survey


Abstract and Figures

A prior national survey documented the high prevalence and costs of alternative medicine use in the United States in 1990. To document trends in alternative medicine use in the United States between 1990 and 1997. Nationally representative random household telephone surveys using comparable key questions were conducted in 1991 and 1997 measuring utilization in 1990 and 1997, respectively. A total of 1539 adults in 1991 and 2055 in 1997. Prevalence, estimated costs, and disclosure of alternative therapies to physicians. Use of at least 1 of 16 alternative therapies during the previous year increased from 33.8% in 1990 to 42.1% in 1997 (P < or = .001). The therapies increasing the most included herbal medicine, massage, megavitamins, self-help groups, folk remedies, energy healing, and homeopathy. The probability of users visiting an alternative medicine practitioner increased from 36.3% to 46.3% (P = .002). In both surveys alternative therapies were used most frequently for chronic conditions, including back problems, anxiety, depression, and headaches. There was no significant change in disclosure rates between the 2 survey years; 39.8% of alternative therapies were disclosed to physicians in 1990 vs 38.5% in 1997. The percentage of users paying entirely out-of-pocket for services provided by alternative medicine practitioners did not change significantly between 1990 (64.0%) and 1997 (58.3%) (P=.36). Extrapolations to the US population suggest a 47.3% increase in total visits to alternative medicine practitioners, from 427 million in 1990 to 629 million in 1997, thereby exceeding total visits to all US primary care physicians. An estimated 15 million adults in 1997 took prescription medications concurrently with herbal remedies and/or high-dose vitamins (18.4% of all prescription users). Estimated expenditures for alternative medicine professional services increased 45.2% between 1990 and 1997 and were conservatively estimated at $21.2 billion in 1997, with at least $12.2 billion paid out-of-pocket. This exceeds the 1997 out-of-pocket expenditures for all US hospitalizations. Total 1997 out-of-pocket expenditures relating to alternative therapies were conservatively estimated at $27.0 billion, which is comparable with the projected 1997 out-of-pocket expenditures for all US physician services. Alternative medicine use and expenditures increased substantially between 1990 and 1997, attributable primarily to an increase in the proportion of the population seeking alternative therapies, rather than increased visits per patient.

ALTERNATIVE medical therapies,
functionally defined as interventions
neither taught widely in medical schools
nor generally available in US hospitals,
have attracted increased national atten-
tion from the media, the medical com-
munity, governmental agencies, and the
public. A 1990 national survey of alter-
native medicine prevalence, costs, and
patterns of use
demonstrated that al-
ternative medicine has a substantial
presence in the US health care system.
Data from a survey in 1994
and a public
opinion poll in 1997
confirmed the ex-
tensive use of alternative medical thera-
pies in the United States. An increasing
number of US insurers and managed
care organizations now offer alternative
medicine programs and benefits.
majority of US medical schools now of-
fer courses on alternative medicine.
National surveys performed outside
the United States suggest that alterna-
tive medicine is popular throughout the
industrialized world.
The percentage of
the population who used alternative
therapies during theprior 12months has
been estimated to be 10% in Denmark
33% in Finland (1982),
and 49%
in Australia (1993).
Public opinion polls
and consumers’association surveyssug-
gest high prevalence rates throughout
Europe and the United Kingdom.
The percentage of the Canadian popula-
tionwho saw analternativetherapyprac-
titioner during the previous 12 months
has been estimated at 15% (1995).
wide range of utilization rates can be
explained, in part, by the disparity in
definitions of alternative therapy and the
selection of therapies assessed.
The presumption is that alternative
medicine use in the United States has
increased at a considerable pace in re-
cent years.The purpose ofthis follow-up
national survey was to investigate this
presumption and document trends in al-
ternative medicine prevalence, costs,
disclosure of use to physicians, and cor-
relates of use since 1990.
We conducted parallel nationally rep-
resentative telephone surveys in 1991
and 1997. Survey methods were ap-
proved by the Beth Israel Deaconess In-
stitutional Review Board, Boston, Mass.

Both surveys used random-digit dialing
to select households and random selec-
tionof 1 householdresident, aged 18years
or older, as the respondent. Eligibility
was limited to English speakers in whom
cognitive or physical impairment did not
prevent completion of the interview. We
asked respondents about their use of al-
ternative therapies during the prior 12
months. We consider the results of the
1991 survey, fielded between January
and March of that year, representative of
1990, and the results of the 1997 survey,
fielded between November 1997 and
February 1998, representative of 1997.
The sampling scheme was designed
with a target sample of 1500 in 1990 and
2000 in 1997. The latter sample size was
chosen to provide power in excess of 80%
to detect an increase from 34% to 39% in
theproportion ofadults whoused at least
1 form of alternative therapy during the
prior 12 months. The actual numbers of
completed interviews were 1539 in 1990
(67% response rate) and 2055 in 1997
(60% weighted response rate). A secular
trend in lower survey response required
us to offer a $20 financial incentive for
participation in the 1997 survey to main-
tain a response rate near the one
achieved in 1990. No financial incentive
was used in the 1990 survey.
The data in each survey were sepa-
rately weighted to adjust for geographic
variation in cooperation (eg, by region of
countryand urbanicity) andfor household
variationin probability ofselection (ie, the
inverse relationship between size of
household and probability of selection be-
cause only 1 interview was completed in
each sample household). The data were
then weighted in parallel on sociodemo-
graphic variables to adjust for aggregate
discrepancies between the sample distri-
butions and population distributions pro-
vided by the US Census Bureau. This last
stage of weighting was based on the 1997
Current Population Survey data
was done in parallel across the 2 surveys
to remove any between-survey discrep-
ancies of weighted sociodemographic dis-
Of the initial sample of 9750 telephone
numbers in 1997, 26% were nonworking,
17% were not assigned to households, and
9% were unavailable (ie, despite 6 at-
tempted follow-up contacts). We de-
clared 481 households ineligible because
respondents did not speak English or
because of cognitive or physical incapac-
ity. Among the remaining 4167 eligible
respondents, 1720 (41.3%) completed the
interview on initial request. Attempts
were then made to convert a random sub-
sample of 1066 refusers by offering them
an increased stipend ($50). A total of 335
(31.4%) of the 1066 contacted were con-
verted in this manner. Extrapolating this
conversion rate to all of the refusers and
weighting the data for the undersam-
pling of initial refusers, we obtained a 60%
(41.3% + [31.4% × (100% 41.3%)])
weighted overall response rate among eli-
gible respondents.
In both years, the interview was pre-
sented as a survey conducted about the
health care practices of Americans by
investigators from Harvard Medical
School. No mention was made of alter-
native or complementary therapies. The
substantive questions began by asking
about perceived health, health worries,
days spent in bed, and functional impair-
ment due to health problems. We then
asked respondents about their interac-
tions with a medical doctor, defined as “a
medical doctor (MD) or a doctor of os-
teopathic medicine (DO), not a chiro-
practoror other nonmedical doctor.” The
term medical doctor was used through-
out the remainder of the interview.
To document trends we explored the
following: (1) Respondents in both sur-
veys were presented with a list of com-
mon medical conditions and asked if they
had experienced each of these conditions
during the previous 12 months. (2) Re-
spondents who reported more than 3
conditions were asked to identify their 3
most bothersome or serious medical con-
ditions and were then asked about seeing
a medical doctor for these principal medi-
cal conditions and about the perceived
quality of these interactions. (3) Respon-
dents were asked about their lifetime and
past12-month use of 16 alternativethera-
pies and whether each of these therapies
was used for each of the principal medical
conditions. The 1997 survey also asked
about use for a representative sample of
other medical conditions and expanded
the list of therapies beyond the original
16 assessed in 1990. (4) We distinguished
between use under the supervision of a
practitioner of alternative therapy and
use without such supervision. Respon-
dents who reported supervised use were
asked about their number of visits in the
past 12 months to practitioners of each
therapy.(5) All usersof alternative thera-
pies in 1997 who acknowledged seeing a
medical doctor during the past year were
then asked if they had discussed their use
ofeach therapy witha medical doctor and,
if not, why not.
Prior use of 16 targeted therapies was
explored using a computer-assisted in-
terview transcript, which included the
following clarifications in both 1990 and
1997: When asking about high-dose vi-
tamin or megavitamin therapies, inter-
viewers made clear that the survey
sought information on vitamins not in-
cluding a daily vitamin or vitamin pre-
scribed by a doctor. Prayer or spiritual
healing by others was asked about sepa-
rately from prayer or spiritual practice
for individual health concern. Commer-
cial diet programs were described as
“the kind you have to pay for, but not
including trying to lose or gain weight on
your own.” A lifestyle diet included ex-
amples like vegetarianism or macrobiot-
ics. Questions regarding energy healing
included examples of magnets, energy-
emitting machines, or the “laying on of
hands,” and use of relaxation techniques
was explained using the examples of
meditation or the relaxation response.
The remaining 9 therapies were asked
about without interviewer clarification.
The 1997 survey was longer (average,
30 minutes) than the 1990 survey (aver-
age, 25 minutes) because we sought to
explore a number of areas in more depth.
All the important questions in the 1990
survey were repeated in 1997. These
replicated questions are the focus of the
current report. One major change in the
1997 survey involved replicated ques-
tions: respondents who reported using
more than 3 alternative therapies were
asked in-depth questions (eg, use of a
practitioner of alternative therapies,
number of visits, out-of-pocket ex-
penses, reasons for use) for all such
therapies in 1990 but only for a random
sample of 3 such therapies in 1997. This
was required because of expansion in
both the number of alternative thera-
pies we assessed in 1997 and questions
about each therapy. The 1997 data were
weighted to adjust for this sampling in
making comparisons with the 1990 data.
Insurance Coverage
For each therapy for which respon-
dents said they used services of an alter-
native medicine practitioner, we asked
whether insurance helped pay for any of
the costs of the therapy and whether the
respondent paid any of the costs out-of-
pocket. Based on the answers to these
questions, we calculated the proportion of
users of each therapy who had complete,
partial, or no insurance coverage for that
therapy. We also calculated the overall fre-
quency of insurance coverage by weight-
ing the insurance frequencies within each
therapy by the proportion of all user thera-
pies accounted for by that therapy.
Construction of Cost Measures
The total cost of visits to alternative
medicine practitioners was calculated by
multiplying the number of visits for each
therapy by a per-visit price and adding
the prices of the following therapies: re-
laxation techniques, herbal medicine,
massage therapy, chiropractic care,
megavitamins, self-help groups, imag-
ery techniques, commercial diet, folk rem-

edies, lifestyle diet, energy healing, ho-
meopathy, hypnosis, biofeedback, and
acupuncture. Out-of-pocket costs were
constructed for each therapy by multi-
plying each user’s visits by the full price
of the visit if the user had no insurance
coverage, by 0.2 if the user had partial
insurance coverage, and by zero if insur-
ance paid the full price of the visit. The
assumption of a 20% coinsurance rate
among users with partial insurance cov-
erage should yield a conservative esti-
mate of out-of-pocket costs, because it ig-
nores deductibles and benefit caps and
assumes that insurance benefits for al-
ternative therapy are similar to medical
We calculated costs based on per-visit
prices chosen from typical prices paid for
such services by private insurers using a
Resource-Based Relative Value Scale
system in selected states. We
then recalculated costs using a second set
of prices chosen partly to reflect empirical
dataon theout-of-pocket costspaid by the
respondents, but primarily to represent
conservative estimates of the per-visit
cost of alternative therapies. Total costs
based on this second set of prices should
represent a lower bound on true expen-
Out-of-pocket costs of herbs, megavi-
tamin supplements, and commercial diet
products were calculated by multiplying
the total population of users by the aver-
age out-of-pocket expenditures reported
by respondents who used each of these
products. In 1997, each respondent who
used an alternative therapy was also
asked, “Did you spend any additional
money on things like books, classes,
equipment, or any other items related to
[the alternative therapy] in the past 12
months?” Out-of-pocket expenditures on
these other items were calculated follow-
ing the same procedures used for herbs,
megavitamins,and commercial dietprod-
ucts. Out-of-pocket expenditures on
herbs, megavitamins, commercial diet
products, and related items were based
on actual dollar amounts reported, so
changes between 1990 and 1997 include
inflation. To isolate the increase in the
cost of practitioner visits between 1990
and 1997 solely because of the increase in
the use of alternative therapies, we cal-
culated1990 practitioner costs using 1997
prices. The differences between the 1990
and 1997 costs of practitioner services re-
ported are understated because they do
not take into account inflation, estimated
at 44% by the medical component of the
Consumer Price Index.
Statistical Analysis
Analyses reported herein consist of
computation of prevalence and mean es-
timates and comparisons of these esti-
mates through the years. As the data in
both surveys are weighted, the Taylor
series method was used to compute sig-
nificance tests using SUDAAN soft-
Tests of independence were
used for comparing proportions, while t
tests were used for continuous mea-
sures. Extrapolations of survey esti-
mates to the total population were based
on the assumption that there were 180
million adults living in the US household
population in 1990 and 198 million in
Characteristics of Respondents
The characteristics of the subjects we
interviewed are shown in Table 1. The
sociodemographic characteristics of the
survey sample are similar to the popu-
lation distributions published by the US
Bureau of the Census.
Patterns of Use
Use of alternative therapies in 1997
was not confined to any narrow segment
of society. Rates of use ranged from 32%
to 54% in the wide range of sociodemo-
graphic groups examined. Use was more
common among women (48.9%) than
men (37.8%) (P = .001) and less common
among African Americans (33.1%) than
members of other racial groups (44.5%)
(P = .004). People aged 35 to 49 years re-
ported higher rates of use (50.1%) than
people either older (39.1%) (P = .001) or
younger (41.8%) (P = .003). Use was
higher among those who had some col-
lege education (50.6%) than with no col-
lege education (36.4%) (P = .001) and
more common among people with annual
incomes above $50 000 (48.1%) than with
lower incomes (42.6%) (P = .03). Use was
more common among those in the West
(50.1%) than elsewhere in the United
States (42.1%) (P = .004). With the ex-
ception of observed sex differences in
1997, these patterns are consistent with
those identified in 1990.
Population prevalence estimates of al-
ternative medicine use in 1990 and 1997
are shown in Table 2. The 1990 survey
estimated that 33.8% of the US adult
population (60 million people) used at
least 1 of the 16 alternative therapies
listed, while the 1997 survey estimated
that this proportion increased signifi-
cantly to 42.1% (83 million people). A
comparison of specific therapies in the
first column shows increases in 15 of the
16 therapies; 10 of these were statisti-
cally significant (P # .05). The largest
increases were in the use of herbal medi-
cine, massage, megavitamins, self-help
groups, folk remedies, energy healing,
and homeopathy. Summing Table 2 (first
column) data shows a 65% increase in
total number of therapies used, from 577
therapies per 1000 population in 1990 to
953 per 1000 in 1997.
Several categories of alternative
therapy warrant clarification about the
actual modalities used. Three quarters of
respondents who acknowledged use of
relaxation techniques said they used
meditation. Among those who reported
usingenergy healing, the most frequently
cited technique involved the use of mag-
nets. Other modalities common to this
category included Therapeutic Touch,
Reiki, and energy healing by religious
groups. The use of self-prayer, in contrast
to spiritual or energy healing performed
by others, was investigated in terms of
prevalence of use but not in terms of
costs, referral patterns, or insurance re-
imbursement. All analyses in this article
exclude data involving self-prayer.
Table 2 (second column) shows that a
significantly higher proportion of alter-
native therapy users saw an alternative
medicine practitioner in 1997 (46.3%,
equivalent to 39 million people) than in
1990 (36.3%, equivalent to 22 million
people). Of the 15 therapies for which
the question was asked, the proportion
of users who saw a practitioner in-
creased for 11. However, even in 1997
there were only 5 therapies in which
a majority of users consulted a practi-

tioner: massage, chiropractic, hypnosis,
biofeedback, and acupuncture. Unsuper-
viseduse (ie, a form of expanded self-care)
remains the usual method of use for all
other alternative therapies.
Table 2 (third column) reveals no con-
sistent change in the average number of
visits among respondents who consulted
practitioners of alternative therapy be-
tween 1990 (19.2%) and 1997 (16.3%).
However, because of the increase in the
proportion of people using these thera-
pies, the total number of visits increased
substantially from 1990 to 1997. This
47.3% increase in total visits is largely
because of increases in visits for relax-
ation therapy, massage, chiropractic,
self-help, and energy healing. The visits
to practitioners of alternative therapy in
1997 exceeded the projected number of
visits to all primary care physicians in
the United States by an estimated 243
million(Figure 1).
Visitsto chiroprac-
tors and massage therapists accounted
for nearly half of all visits to practition-
ers of alternative therapies.
Prevalence estimates for selected ad-
ditional therapies assessed in 1997 but not
1990 include: aromatherapy (5.6%), neu-
ral therapy (1.7%), naturopathy (0.7%),
and chelation therapy (0.13%) (data not
shown). Comparisons of total visits and
costs for 1990 and 1997 were performed
without inclusion of these data. Preva-
lence estimates for the simultaneous use
of prescription medications with herbs,
with high-dose vitamins, or with both were
obtained. Among the 44% of adults who
said they regularly take prescription medi-
cations, nearly 1 (18.4%) in 5 reported the
concurrent use of at least 1 herbal prod-
uct, a high-dose vitamin, or both.
Table 3 summarizes results regarding
use of alternative therapies for the most
commonly reported principal medical
conditions in either survey. In each year,
a majority of respondents reported 1 or
more principal medical conditions. The
list of conditions was expanded in 1997
(37 conditions) compared with 1990 (24
conditions). Significant increases in the
proportion using alternative therapies
for principal condition(s) (second col-
umn) occurred for back problems, aller-
gies, arthritis, and digestive problems.
The highest condition-specific rates of
alternative therapy use in 1997 were for
neck (57.0%) and back (47.6%) problems.
The proportion of respondents with 1 or
more medical conditions who reported
use of an alternative therapy for at least
1 of those conditions increased signifi-
cantly from 22.9% in 1990 to 33.7% in
1997 (P#.001). The weighted condition-
specific proportion who saw an alterna-
tive medicine practitioner for a given
condition also increased significantly
from 6.8% in 1990 to 11.4% in 1997
Table 3 also summarizes the probabil-
ity that individuals who saw a medical
doctor for a particular condition also used
an alternative therapy (fourth column) or
also saw a practitioner of alternative
therapy (fifth column) for that same con-
dition during the same year. A generally
increasing pattern of alternative medi-
cine use can be seen across the range of
conditions studied. In 1990, an estimated
1 (19.9%) in 5 individuals seeing a medical
doctor for a principal condition also used
an alternative therapy. This percentage
increased to nearly 1 (31.8%) in 3 in 1997
(P#.001). The percentage who saw a
medical doctor and also sought the ser-
vices of an alternative practitioner in-
creased significantly from 8.3% in 1990 to
13.7% in 1997 (P#.01). In both 1990 and
1997, chiropractic, relaxation techniques,
and massage therapy were among the al-

ternative therapies used most commonly
to treat principal medical conditions.
As in 1990, 96% of 1997 respondents who
saw a practitioner of alternative therapy
for a principal condition also saw a medi-
cal doctor during the prior 12 months, and
only a minority of alternative therapies
used were discussed with a medical doc-
tor. Among the 618 respondents in 1997
who used 1 or more alternative therapies
and had a medical doctor, only 377 (38.5%)
of the 979 therapies used were discussed
with the respondent’s medical doctor. This
is not significantly different from the 353
(39.8%) of the 886 therapies discussed by
the comparable group of respondents
(n = 501) in the 1990 survey. Given that
most alternative therapy is used without
the supervision of an alternative practi-
tioner, a substantial portion of alterna-
tive therapy use for principal medical con-
ditions (46.0% in 1997 and 51.3% in 1990)
was done without input from either a
medical doctor or practitioner of alterna-
tive therapy.
Payment for Alternative Therapy
Data on insurance coverage of expen-
ditures for alternative therapy services
are shown in Table 4. The majority of
people who saw alternative therapy
practitioners paid all the costs out-of-
pocket in both 1990 (64.0%) and 1997
(58.3%). None of the changes in insur-
ance coverage between 1990 and 1997
were statistically significant, probably
due in part to small sample sizes.
Using conservative assumptions about
the fees charged by practitioners of
alternative therapies and assuming no
changes in visit prices, Americans spent
anestimated$14.6 billion onvisits to these
practitioners in 1990 and $21.2 billion in
1997 (Table 5). Using less conservative
(RVRBS) price figures, the amount spent
on services of practitioners of alternative
therapies was estimated at $22.6 billion in
1990 and $32.7 billion in 1997. Regardless
of which set of prices is used, total expen-
ditures for practitioners of alternative
therapies are estimated to have increased
by approximately 45% between 1990 and
1997 exclusive of inflation.
Estimated out-of-pocket expenditures
for high-dose vitamins increased from
$0.9 billion in 1990 to $3.3 billion in 1997.
Smallerincreases were observedfor com-
mercial diet products ($1.3 billion vs $1.7
billion). Unlike the 1990 survey, the 1997
survey included questions about expen-
ditures for herbal products ($5.1 billion)
and respondents’ alternative therapy–
specific books, classes, or equipment
($4.7 billion).
The estimated total out-of-pocket
component of the alternative medicine
market in 1997 is shown in Figure 2. Pro-
jected out-of-pocket expenditures for all
hospitalizations in 1997 in the United
States totaled $9.1 billion, while projected
out-of-pocket expenses for all US physi-
cian services in the same year were $29.3
This compares to a conserva-
tively estimated $12.2 billion in out-of-
pocket payments to alternative medicine
practitioners for the 15 therapies studied.
Adding the estimates of $5.1 billion for
herbal therapies, $3.3 billion for megavi-
tamins, $1.7 billion for diet products, and
$4.7 billion on alternative therapy–spe-
cific books, classes, and equipment, the
totalout-of-pocketexpenditures for alter-
native medicine are conservatively esti-
mated to be $27.0 billion. Using the aver-
age per-visit prices derived from an
RBRVS system
rather than our conser-
vative estimates (Table 5), the estimated
total out-of-pocket expense is approxi-
mately $34.4 billion, which is comparable
with the projected 1997 out-of-pocket ex-
penditures for all physician services.
These estimates exclude out-of-pocket
expenditures associated with therapies
unique to the 1997 survey (eg, naturopa-
thy, aromatherapy, neural therapy, and
chelation therapy).
The results of our study are limited by
the restriction of the sampling frame to
people who speak English and have tele-
phonesand bythe lowresponse rate. The
decrease in overall response rate from
67% in 1990 to 60% in 1997 is consistent
with secular trends for US telephone in-
terviews in recent years.
It is difficult
to know what, if any, bias was introduced
or whether trend estimates are biased
by the fact that financial incentives were
used in 1997 but not 1990. Furthermore,
we have no data on the accuracy of self-

reports concerning recollections of num-
ber of visits and amounts spent on books,
classes, relevant equipment, herbs, or
supplements. To the extent possible, we
adjusted by weighting data on sociode-
mographic variables associated with al-
ternative therapy use (eg, income, edu-
cation, age, region). It is conceivable that
the estimated prevalence and costs of al-
ternative therapy use would have been
lower if it were possible to correct for
those limitations.
Within the context of these limitations,
theresults of these2 surveys suggestthat
the prevalence and expenditures associ-
ated with alternative medical therapies
in the United States have increased sub-
stantiallyfrom 1990 to 1997. Thisincrease
appears to be primarily due to increases
in the prevalence of use and in the fre-
quency with which users of alternative
therapy sought professional services. In
1997,an estimated 4 in 10Americans used
at least 1 alternative therapy as com-
pared with 3 in 10 in 1990. For adults aged
35 to 49 years in 1997, it is estimated that
1 of every 2 persons used at least 1 alter-
native therapy. Overall prevalence of use
increased by 25%, total visits by an esti-
mated 47%, and expenditures on services
provided by practitioners of alternative
therapies by an estimated 45% exclusive
of inflation. Moreover, the use of alterna-
tivetherapies is distributed widelyacross
all sociodemographic groups.
It is possible to arrange the 16 princi-
pal therapies common to the 1990 and
1997 surveys along a spectrum that var-
ies from “more alternative” to “less alter-
native” in relationship to existing medi-
cal school curricula, clinical training, and
practice. Arguably, therapies such as bio-
feedback, hypnosis, guided imagery, re-
laxation techniques that involve elicita-
tion of the relaxation response (,1% of
the sample), lifestyle diet, and (possibly)
vitamintherapy can be considered asrep-
resentative of the more conventional (ie,
less alternative) side of the spectrum.
Visits associated with these 6 categories
accounted for less than 10% of total visits
to alternative medicine practitioners; the
remainderwere associated with the more
alternative therapies.
In light of the observed 380% increase
in the use of herbal remedies and the
130% increase in high-dose vitamin use,
it is not surprising to find that nearly 1 in
5 individuals taking prescription medi-
cations also was taking herbs, high-dose
vitamin supplements, or both. Extrapo-
lations to the total US population sug-
gest that an estimated 15 million adults
are at risk for potential adverse interac-

tions involving prescription medications
and herbs or high-dose vitamin supple-
ments. This figure includes nearly 3
million adults aged 65 years or older. Ad-
verse interactions of this nature, includ-
ing alterations of drug bioavailability
or efficacy, are known to occur
are more likely among individuals with
chronic medical illness, especially those
with liver or kidney abnormalities. No
adequate mechanism currently is in
place to collect relevant surveillance
data to document the extent to which the
potential for drug-herb and drug-vita-
min interaction is real or imaginary.
The magnitude of the demand for al-
ternative therapy is noteworthy, in light
of the relatively low rates of insurance
coverage for these services. Unlike hos-
pitalizations and physician services, al-
ternative therapies are only infrequently
included in insurance benefits. Even
when alternative therapies are covered,
they tend to have high deductibles and
co-payments and tend to be subject to
stringent limits on the number of visits or
total dollar coverage. Because the de-
mand for health care (and presumably al-
ternative therapies) is sensitive to how
much patients must pay out-of-pocket,
current use is likely to underrepresent
utilization patterns if insurance coverage
for alternative therapies increases in the
In 1990, a full third of respondents who
used alternative therapy did not use it
for any principal medical condition.
From these data, we inferred that a sub-
stantial amount of alternative therapy
was used for health promotion or disease
prevention. In 1997, 42% of all alterna-
tive therapies used were exclusively at-
tributed to treatment of existing illness,
whereas 58% were used, at least in part,
to “prevent future illness from occur-
ring or to maintain health and vitality.”
Despite the dramatic increases in use
and expenditures associated with alter-
native medical care, the extent to which
patients disclose their use of alternative
therapiesto their physiciansremains low.
Less than 40% of the alternative thera-
pies used were disclosed to a physician in
both 1990 and 1997. It would be overly
simplistic to blame either the patient or
their physician for this inadequacy in pa-
tient-physician communication. The cur-
rent status quo, which can be described
as “don’t ask and don’t tell,” needs to be
Professional strategies for
responsible dialogue in this area need to
be further developed and refined.
Data from this survey, reflective of
the US population, are representative of
a predominantly white population. Even
if we were to combine data sets from the
1990 and 1997 surveys, we would not
have a sufficiently large database to pro-
vide precise estimates of the patterns of
alternative therapy use among African
Americans, Hispanic Americans, Asian
Americans, or other minority groups.
Parallel surveys, modified to include
therapiesunique to minority populations
andtranslated when appropriate, should
be conducted using necessary sampling
strategies. Only then can we compare
patterns across ethnic groups and pri-
oritize research agendas for individual
populations. As alternative medicine is
introduced by third-party payers as an
attractive insurance product, it would be
unfair for individuals without health in-
surance and those with less expendable
income to be excluded from useful alter-
native medical services or consultation
(eg, professional advice on use or avoid-
ance of alternative therapies).
In conclusion, our survey confirms
that alternative medicine use and expen-
ditures have increased dramatically
from 1990 to 1997. In light of these ob-
servations, we suggest that federal
agencies, private corporations, founda-
tions, and academic institutions adopt a
more proactive posture concerning the
implementation of clinical and basic sci-
ence research, the development of rel-
evant educational curricula, credential-
ing and referral guidelines, improved
quality control of dietary supplements,
and the establishment of postmarket
surveillance of drug-herb (and drug-
supplement) interactions.

... Furthermore, the Foundation also identified five major disciplines for initial research and regulation: herbalism, acupuncture, homeopathy, chiropractic and osteopathy and urged the use of alternative research methodologies where these are appropriate to study purpose (Coates and Jobst 1998). I would argue that this prioritisation is consistent with the suggestion that herbalism is one of the most popular complementary therapies in both the United States (Eisenberg et al 1998, Eisenberg et a11993) and the United Kingdom (Ernst and White 2000, Thomas et a11993) and that it lends credibility to the view that herbalism is an increasingly popular health care choice outside mainstream medicine (Capriotti 1999, Ernst 1999. ...
... The popularity of complementary therapies within the westemised population is well documented, the literature reflecting common trends across most of the western continents (Ernst and White 2000, Eisenberg et al 1998, MacLennan et al 1996, Vickers 1994. Of particular importance is the observation that the use of complementary therapies is noted to have significantly increased in westemised society in recent years (Coates and Jobst 1998) although a more recent systematic review of the literature identified that reliable prevalence statistics were evident in only three studies (Harris and Rees 2000). ...
... American study was replicated in 1997 to reveal that the overall rate of use of complementary therapies had risen from 34% to 42% with an increase in practitioner consultations from 36% to 46% (Eisenberg et al 1998). The same two studies reported the rate of use of herbal therapies to have increased by 380% during the same period. ...
p>Set in the south of England, the study applies an interpretative research methodology to expose the views of 19 adults, who were interviewed in relation to their experiences of medical herbalism. The study reveals how participants discriminated between acute health care, which was adequately provided in the conventional setting, and everyday health care, which they found in medical herbalism. Participants valued medical herbalism for its perceived effectiveness; where effectiveness was defined according to participants’ personal criteria, where it was judged according to their personal experiences of improved health and well-being and where confidence in its healing potential was reinforced by knowledge of its enduring history. In medical herbalism, participants also experienced a patient-practitioner relationship that was founded on corresponding ideas about the nature and purpose of health care. Being conducive to the development of mutual understanding, the nature of this relationship therefore emerged as a central factor in the provision of effective health care, especially in relation to the individualisation of health care treatment. The study suggests a complementary relationship between herbal and conventional health care but signals a desire for a medical pluralism that has the potential to accommodate participants’ health care needs in totality. It offers an alternative patient perspective on health care: one that emphasises the importance of consensus and self-determination but that also recognises the necessity for health care to have relevance and meaning, from the patient’s unique perspective.</p
... Cupping treatment, a traditional medicine practiced for approximately 3,000 years in which local suction is created on the skin by applying heated cups, has become a popular alternative approach for treating various ailments worldwide, including spinal pain and herpes neuralgia (6,7). Some studies have shown its effects on both local and system, wherein cupping stretches the skin and underlying tissue and dilates the capillaries, eventually leading to capillary rupture and ecchymosis (8). ...

Subdural hematoma (SDH) is one of the most lethal types of traumatic brain injury. SDH caused by Intracranial Pressure Reduction (ICPR) is rare, and the mechanism remains unclear. Here, we report three cases of SDH that occurred after substandard cupping therapy and are conjected to be associated with ICPR. All of them had undergone cupping treatments. On the last cupping procedure, they experienced a severe headache after the cup placed on the occipital-neck junction (ONJ) was suddenly removed and were diagnosed with SDH the next day. In standard cupping therapy, the cups are not usually placed on the ONJ. We speculate that removing these cups on the soft tissue over the cisterna magna repeatedly created localized negative pressure, caused temporary but repeated ICPR, and eventually led to SDH development. The Monro-Kellie Doctrine can explain the mechanism behind this - it states that the intracranial pressure is regulated by a fixed system, with any change in one component causing a compensatory change in the other. The repeated ICPR promoted brain displacement, tearing of the bridging veins, and development of SDH. The literature was reviewed to illustrate the common etiologies and therapies of secondary ICPR-associated SDH. Despite the popularity of cupping therapy, its side effects are rarely mentioned. This case is reported to remind professional technicians to fully assess a patient's condition before cupping therapy and ensure that the cups are not placed at the ONJ.
... The increase in expenditure to HDS use has increased dramatically in other countries. 21,22 In an Italian multicenter survey, patients were noted to spend a large proportion of their income to HDS. 8 A local study of cancer patients revealed a mean monthly expenditure on HDS exceeding 25% of the mean income. 4 Despite being classified under poor-to low-income cluster in economic status, 14,23 our findings highlight important implications with HDS use in the financial burden in this population whose funds are already limited by costs of livelihood and conventional treatment. ...

The use of herbal and dietary supplement in cancer patients has been increasing over the past years, while the risk of its adverse effects and undesirable reactions with conventional treatment has also been accumulating. Limited studies involving perception of herbal and dietary supplements (HDS) by cancer patients have been conducted in our setting. An initial survey was conducted among adult cancer patients undergoing treatment at the Zamboanga City Medical Center (ZCMC) Cancer Institute. HDS users were recruited for focus group discussion (FGD) via purposive sampling. A total of four groups were conducted. Clinical and demographic data were presented through descriptive statistics while data from the FGD were subjected to coding and thematic analysis. Among 22 respondents, more than half (65.4%) of the participants were noted to have used HDS and most (54.5%) were breast cancer patients with stage-II and -III disease. Treatment of cancer, coping with chemotherapy, and relief of symptoms were the major reasons for use. Majority (36.36%) were influenced by the media/internet and most (50%) did not disclose information to their physician. Eight respondents, whose income were below minimum wage, spent more than 25% of their income on HDS, with some having spent more than 50%. This may seriously limit funds and result in failure to adhere to treatment. Among cancer patients in ZCMC, HDS use is widely practiced and half of them do not disclose this information to their physicians. The expenditure on HDS consumes 25 to 50% of the population's meager monthly income. The secrecy surrounding its use and attendant cost may possibly limit adherence and adversely affect outcomes.

La esperanza en la biomedicina para superar la pandemia de la COVID-19 no significa que otras epidemias no se encadenen en el futuro, como lo ha demostrado la cantidad de epidemias surgidas en el correr de este siglo. El artículo analiza el mito de la neutralidad de la tecnología en relación con la tecnología biomédica, para concluir mostrando la importancia de los mecanismos ideológicos y legales, así como las tendencias intrínsecas a la propia biomedicina para que el sector biomédico hegemónico y la industria asociada sean aceptados por la percepción global como una solución a un problema que es lejos de ser pasajero. El caso en cuestión llama la atención para los educadores ambientales que como resultado de prácticas en gran medida de gestión, tienden a tomar las posiciones científicas hegemónicas acríticamente. Palabras-clave: neutralidad de la tecnología; biomedicina; big pharma; capitalismo.

Medicinal plants are those that have curative qualities or have positive pharmacological effects on the human body. Herbal-drug interactions are more likely when medicinal plants are taken at the same time as prescription medications. The specific plant, medicine, and patient profile all influence how clinically significant herbal-drug interactions are. As they alter bodily processes, herbs have the potential to be powerful. As herbal medicines and supplements are not subject to NAFDAC assessment, using them can be harmful. We attempt to explore potential causes, kinds, and reported examples of toxicities associated with the use of herbal therapy alone as well as some herbal drug interactions. Additionally, several strategies to lessen the negative effects of herbal medicines have been discussed.
Since the dawn of humankind, humans have relied on plant-based medicines for the majority of their health and disease needs. The rapid and increasing rise in the worldwide use of herbal medicines in recent decades suggests botanical medicines, both traditional and modern, fulfill a therapeutic niche not adequately addressed in modern health care delivery systems. At the same time, there is a propensity, predominantly in developed, but also developing nations, to develop herbal medicines in the same manner as modern chemically characterized drugs. This trend is driven partly by a belief that the same regulatory requirements that are applied to modern pharmaceuticals should be applied to herbal medicines and partly by economics, a subject not often discussed.
p>Use of complementary and alternative medicine (CAM) is substantial in the UK. This thesis is about why people return to CAM, in other words why people continue to use adhere to CAM. Two new questionnaire measures were developed. The CAM Beliefs Inventory (CAMBI) was developed as a generic measure of treatment beliefs relevant to CAM which can be used in a range of CAM settings. The Treatment Process Questionnaire (TPQ) was developed as a generic measure of peoples’ experiences of non-pharmacological treatments and can be used in both CAM and non-CAM settings. Two questionnaire studies were conducted to examine the relative importance of different beliefs in ongoing CAM use. The cross-sectional study found that beliefs in holistic health were the most important predictors of CAM use across different CAM treatments. The prospective questionnaire study examined the relationship between beliefs, experiences of treatment, and adherence to CAM. This study showed that positive experiences of treatment are the most important predictors of adherence to CAM, compared to treatment and illness beliefs. A qualitative study using ethnographic and grounded theory techniques was conducted to examine the process involved in ongoing CAM use. This study developed a process-oriented model of CAM use which suggested ways in which people experience and evaluate CAM therapies, and highlighted the way in which individuals’ health care decisions are embedded in the socio-cultural context. Overall this programme of research has provided rigorous and well-validated insights with questionnaire measures and valuable theory-driven processes in a much under-researched and over-debated area.</p
This study focuses on the use of alternative health care practitioners by Canadians aged 15 and over using data from the 1994–95 National Population Health Survey. A total of 17,626 respondents were selected. Consultation with an alternative health care provider or with a chiropractor was deemed to be an indicator of the use of alternative health care. In 1994–95, an estimated 15% of Canadians aged 15 and over (3.3 million people) used some form of alternative health care in the year preceding the survey. Use of alternative health care was most prevalent among women, persons aged 45–64 and among higher income groups. The use of alternative health care was associated with the number of diagnosed chronic illnesses. Among persons free of chronic diseases, 9% consulted alternative health care providers compared with 26% of those with three or more chronic conditions. Since the population is aging, the proportion with multiple chronic illness will also increase, with consequent demand for services from alternative health practitioners. The inclusion of any alternative practitioner services under existing health care plans could result in higher health care costs.
Medicines derived from plants formed the majority of the earlier materia medica because chemically synthesised compounds were then not available. Many of these herbs have stood the test of time and critical clinical assessment and have found their way into the pharmacopoeias of orthodox medicines sometimes as the isolated and chemically standardised active ingredient. Such drugs as cocaine, colchicine, coumarin anticoagulants, digoxin, ephedrine, morphine, quinine and quinidine, reserpine, tubocurarine, sennosides, and the ergot and vinca alkaloids entered orthodox medicinal use by this route.
Context.— With the public's increasing use of complementary and alternative medicine, medical schools must consider the challenge of educating physicians about these therapies.Objectives.— To document the prevalence, scope, and diversity of medical school education in complementary and alternative therapy topics and to obtain information about the organizational and academic features of these courses.Design.— Mail survey and follow-up letter and telephone survey conducted in 1997-1998.Participants.— Academic or curriculum deans and faculty at each of the 125 US medical schools.Main Outcome Measures.— Courses taught at US medical schools and administrative and educational characteristics of these courses.Results.— Replies were received from 117 (94%) of the 125 US medical schools. Of schools that replied, 75 (64%) reported offering elective courses in complementary or alternative medicine or including these topics in required courses. Of the 123 courses reported, 84 (68%) were stand-alone electives, 38 (31%) were part of required courses, and one (1%) was part of an elective. Thirty-eight courses (31%) were offered by departments of family practice and 14 (11%) by departments of medicine or internal medicine. Educational formats included lectures, practitioner lecture and/or demonstration, and patient presentations. Common topics included chiropractic, acupuncture, homeopathy, herbal therapies, and mind-body techniques.Conclusions.— There is tremendous heterogeneity and diversity in content, format, and requirements among courses in complementary and alternative medicine at US medical schools.
Herbal medicines have become a popular form of therapy. They are often perceived as being natural and therefore harmless. This article reviews the recent literature on the adverse effects of herbal remedies. Examples of allergic reactions, toxic reactions, adverse effects related to an herb's desired pharmacological actions, possible mutagenic effects, drug interactions, drug contamination, and mistaken plant identities are provided. Because of underreporting, our present knowledge may well be just the "tip of the iceberg." Little is known about the relative safety of herbal remedies compared to synthetic drug treatments, although for some herbal remedies, the risks may be less than for conventional drugs.
