Multani Mitti – Is it
more than a placebo?
“Multani mitti” or Fuller’s earth is a popular
substance as home remedy in South Asia. It has
been traditionally used as a cleanser for skin and
hair in this part of the world for centuries.
Though Fuller’s earth was used for cleaning
wool in Europe, and in modern times is used to
bleach oils or drill mud, as adsorbent and even
in film industry to form dust clouds or as mud
bath. People in South Asia, particulary India,
Pakistan and Nepal use Multani mitti in daily
life as face packs for enhancing their beauty or
to cleanse hair. Often dermatology patients seek
advice on using this readily available substance,
in this scenario it is pertinent for clinicians to be
aware of pros and cons of usage of Multani
mitti.
“Multani mitti” is a popular home remedy
amongst South Asians, either as cosmetic or in
herbal products. Dermatologists frequently hear
patients narrating their experience about natural/
herbal therapies for their ailments including
“Multani mitti”. Multani mitti has been in
existence in Asian homes for centuries, however
first documentation of its use was made only
during colonial rule.1
Majority of patients attending dermatology
clinics in South Asian have used Multani mitti, a
parting question “can I continue using Multani
mitti on my skin” or “will it cause any harm if I
use it?” leaves the treating physician unsure
about how to address this query. We, therefore
have explored this ubiquitous substance in
detail, analyse implications of its use in
dermatologic practice.
Multani mitti or Fuller's earth is any clay
material that has the capability to decolourize oil
or liquids without chemical treatment.2,3 It is an
adsorbent clay consisting essentially of calcium
montmorillonite. Montmorillonite is an
aluminium silicate of approximate formula
(Al,Fe,Mg)4Si8O20(0H)4, in which the relative
amounts of Al, Fe, and Mg are not fixed. It
should be distinguished from sodium
montmorillonite, often known as bentonite.4
"Activated" Fuller's earth is obtained by
chemical treatment. In addition to calcium
montmorillonite, Fuller's earth contains small
amounts of natural impurities, namely, calcite,
feldspar, zinc blend, apatite, limonite, and rarely
quartz. The earth when quarried is a grey, soap-
like substance and; is basically crystalline.
Electron microscope studies have shown these
crystals to be very small, approximately
0.4x0.004 microns. Despite this basic crystalline
structure the powder behaves as though it were
amorphous. Its high adsorptive, base exchange,
and bonding properties give it, its importance as
an industrial substance.4 Ancient Greeks and
Romans knew Fuller's earth as bleach and as a
primitive soap. By the middle ages it was mainly
used for scouring raw wool, for removing
surplus dye from cloth, and finishing and
thickening ("fulling") woolen cloth. It was at
one time such a mainstay of the British woolen
industry that smuggling it out of the country was
a serious offence. It has also been used as a base
for cosmetics, powders (e.g., baby/ napkin/ toilet
powder) etc., currently its main uses are in
industrial processes, such as refining lubricating
oils, edible oils and technical oils. It is also used
for bonding foundry moulding sand and for oil-
well drilling.4

Etymology
Multani mitti is a clay which gets its name from
a town – Multan (in pre-partitioned India), now
in Pakistan. Referred to as “Fuller’s earth”, in
the west, derives the name from cleaning
process of wool; which involved rubbing it on
wool and then washing it off thus the dirt and
grease would be removed and wool appeared
fuller or fluffy.
Chemical Properties
Multani mitti is essentially a clay consisting of
Aluminium Silicate with other impurities in
minimal proportions. Not much mention is made
of its composition in Indian literature as opposed
to the west. The composition may vary
according to the area from where it is mined.
Earliest reference from India was made about
Jodhpur (Kapurdi) clay1consisting of :
SiO2 47%
Al2O3 23.3%
Fe2O3 6.95%
CaO 2.9%
MgO traces
Multani mitti is a non-plastic clay with enough
of water content. Among the properties formerly
attributed to fuller’s earth are non-plasticity,
disintegrating in water, detergent action, large
water content, and the property of adhering to
tongue. Fuller’s earth, as a rule, is lighter and
more porous than other clays.5
Usage
Multani mitti was traditionally used for cleaning
wool when it was referred to as fuller’s earth in
the west. Used as a cleanser for face or hair in
India, it is popular as a material for baths among
mud bath enthusiasts in USA, ironically mud
baths have never been popular among Asians,
though this clay has been around forever.
Fuller’s earth was used in the laboratory to
detect the addition of certain colouring matters
to butter, whiskey, and artificial vinegar. In
pharmacy it makes an excellent substitute for
talcum powder, on account of its absorptive
power. It was used as poultice for swellings,
ulcers and sores.5
The major use of Fuller’s earth are in drilling
mud, foundry-sand bond, binder for pelletizing
iron ore. The minor uses include carrier for
insecticides and fertilizers, filler in paint,
adhesive and pharmaceutical products, binder
for animal feed, sealant for waterproofing
reservoirs and canals. It is used as soil liner for
water treatment in Texas to contain
petrochemical waste dumps and treating
industrial ponds. It is also used with
polyacrylamide to make paper.2
Mulani mitti may be used to treat paraquat
poisoning.6 It is used by military and civil
service personnel to decontaminate clothing and
equipment of responders who have been
contaminated with chemical agents.7 Cat litter is
cleaned using fuller’s earth. In the film industry
Fuller’s earth has been extensively for special
effects, pyrotechnics explosions, making dust
clouds because it spreads farther and higher than
most natural soils, resulting in a blast that looks
larger. Film set dressers use it to convert paved
streets into dirt roads, also to create dust trailing
from a moving vehicle on a road.7
Oil drilling, bleaching of oils are some other
uses where Multani mitti is employed, it is dug
out from mines in the United states of America
(USA) and England for industrial uses.2 Among
cosmetic uses it was used in Asia alone and is
still in practice though no scientific evidence of
therapeutic effects support these claims. Due to
its excellent adsorbing quality it may be argued
that Multani mitti helps to remove oil/ sebum
from the face or hair. It is used to bleach edible

oils, this property may be have been unwittingly
used at least theoretically, to bleach the skin. It
is reportedly consumed by pregnant women in
Pakistan.8 Geophagy is an accepted social evil in
several countries. It is related to nutritional
deficiency which prompts them to eat mud, also
sold commercially in many countries.9,10 Multani
mitti has also been traditionally used on Taj
Mahal to maintain the shine on the marble.11
Several mud packs are marketed as face wash in
cosmetics industry. Pharmacological journals
from India have published few papers on
experimenting various ratios of Multani mitti for
face wash/ face packs.12,13 Nonetheless there is
not a single publication on use or effects or
adverse effects of this clay, they all just go
ahead on the presumption that it is indeed
scientifically therapeutic, playing to commercial
audience.
Conclusion
After browsing literature on Multani mitti it
would be alright to conclude that this clay seems
to give a sense of satisfaction and that is the only
effect it seems to have on its users. In the
absence of scientific scrutiny on its use, effects
or adverse effects it can be opined that Multani
mitti has no role as a therapy in dermatology.
Therefore we can safely convey that there is no
scientific evidence of its efficacy whatsoever,
and public may use it on their own discretion if
they may want. This corollary acquires special
importance in the era when every yes or no from
medics may be subjected to close legal scrutiny.
