Background
Traditional medicine (TM) plays a significant role in healthcare either as part of the primary healthcare system or as an adjunct to conventional medicine. This study aimed to map systematic reviews (SRs) of TM modalities across health conditions and identify gaps in the research literature to facilitate priority setting in future TM res...
Background
Cancer is the leading cause of death in Norway, with prostate, breast, lung, and colon cancers being the most prevalent types. Adopting a healthy and varied diet can help reduce cancer risk and recurrence. However, access to dietary counselling remains limited for cancer patients in Norway. This study aimed to investigate the prevalence...
Introduction
Traditional medicine (TM) is an important part of healthcare either as the main healthcare system or as a complement to conventional medicine. The effectiveness of TM has been assessed in clinical trials that have been synthesised into thousands of systematic reviews (SRs). This study is commissioned by the World Health Organization (W...
Background
The increasing number of patients surviving cancer leads to more people experiencing late and long term-effects from the disease and its treatment. Fatigue, sleep disorders, early menopause, pain, and nerve damage are commonly reported. Methods helping people to recover after cancer treatment are therefore essential. The aims of this stu...
Background
Research exploring the use of specific Complementary and Alternative Medicine (CAM) modalities by Norwegian cancer patients is sparse. The aims of this study were therefor to map the different CAM modalities cancer patients use and further investigate their rationale for use, communication about use, self-reported benefits and harms, and...
Objectives
The present study was initiated to determine consultations with health care providers and use of self-management strategies for prevention or treatment of COVID-19 related symptoms in countries with a full lockdown (Norway), a partial lockdown (the Netherlands) and no lockdown (Sweden) during the first three months of the COVID-19 pandem...
Background

Objective:
The aim of this systematic review was to identify and evaluate the literature on concurrent prescription and H...
Background: Hypercholesterolaemia is directly associated with an increased risk for coronary heart disease and other sequelae of atherosclerosis. Artichoke leaf extract (ALE) has been implicated in lowering cholesterol levels. Whether ALE is truly effective for this indication is still a matter of debate. This is an update of a review first publish...
Background:
There has been a global increase in the use of herbal medicinal products (HMPs). About a quarter of UK adults use HMPs, bought over the counter by self-prescription and often not disclosed to healthcare professionals. Potential herb-drug interaction is a clinical concern, with older people at greater risk because of co-morbidities and...

The popularity of herbal medicines has risen worldwide. This increase in usage renders safety issues important. Many adverse events of herbal medicines can be attributed to the poor quality of the raw materials or the finished products. Different types of herbal medicines are associated with different problems. Quality issues of herbal medicines ca...
The aim of this systematic review is to examine the efficacy of Garcinia extract, hydroxycitric acid (HCA) as a weight reduction agent, using data from randomised clinical trials (RCTs). Electronic and nonelectronic searches were conducted to identify relevant articles, with no restrictions in language or time. Two independent reviewers extracted t...
In many countries, recent data on the use of complementary and alternative medicine (CAM) are available. However, in England, there is a paucity of such data. We sought to determine the prevalence and predictors of CAM use in England.
Data were obtained from the Health Survey for England 2005, a national household survey that included questions on...
Objective:
This discussion document about the management of cancer pain is written from the pain specialists' perspective in order to provoke thought and interest in a multimodal approach to the management of cancer pain, not just towards the end of life, but pain at diagnosis, as a consequence of cancer therapies, and in cancer survivors. It rela...
Systematic reviews (SRs) are considered the best tools for summarizing the evidence for or against the effectiveness of health care interventions. The principles and methods of SRs apply equally to both, mainstream and complementary/alternative medicine (CAM). Certain challenges are, however, more commonly encountered in CAM or even specific to it;...
Complementary and alternative medicine Complementary and alternative medicines (CAM) encompass a very diverse array of treatment modalities and diagnostic techniques. Th ey have in common that they are not presently considered part of conventional/mainstream medicine and emphasize a holistic approach towards health care. A number of terms and defin...

The aim of this article is to evaluate trends in the development of the evidence-base for the effectiveness of massage therapy. For this purpose, a comparison of two systematic reviews was conducted. The first related to the evidence-base in 2000, the second to 2005. Both employed the same methodology and criteria for evaluation. The results indica...
The effectiveness of mind-body therapies is sometimes doubted.

Sixty-two (1999) and 60 (2002) answers were received corresponding to response rates of 62% and 55%. The total CAM re...
Editor—Arguably clinical trials are the most important basis for evidence based medicine. So why are more such investigations not funded in the United Kingdom?
Both in 1999 and 2002 we sent a custom made questionnaire to all medicine charities listed in the Association of Medical Research Charities Handbook 2001, inquiring about the level of fundi...
