The research Evidence Base for Homeopathy

The Research Evidence Base for HomeopathySystematic reviews of randomised controlled trials (RCTs) of homeopathy
• Two major reviews of RCTs of individualised homeopathyhave reached broadly positive conclusions.

•  Four of ­five major comprehensive reviews of RCTs in homeopathy have reached broadly positive conclusions.
Only Based on a smaller selection of trials, a ­fth review came to a negative conclusion about homeopathy.

• Positive conclusions have been reported in 9 of 35 reviews of RCTs in speci­c categories of medical condition (the other 26 are largely inconclusive):
     •allergies and upper respiratory tract infections

     •childhood diarrhoea

     •post-operative ileus

     •rheumatic diseases

     •seasonal allergic rhinitis

     •vertigo

Placebo-controlled RCTs of homeopathy - the original data

Up to the end of 2014, the peer-reviewed literature included 153 papers reporting
placebo-controlled RCTs, of which 104 have data eligible for our analysis: 43 positive;
5 negative; 56 not statistically conclusive. In addition to the medical conditions above,
there is a positive balance of evidence in the following, for example:
     •influenza

     •insomnia

     •sinusitis

There is evidence from singleton placebo-controlled RCTs in favour of homeopathy for
a number of other conditions including: 
     - bronchitis,

     - chronic fatigue syndrome,

­     - fibromyalgia,

     - premenstrual syndrome.

Cost effectiveness of homeopathy

• 70.7% of 6,554 follow-up patients, treated at Bristol Homeopathic Hospital for a wide
range of chronic medical complaints, reported positive health changes.
31
•
Many patients who attended the Royal London Homeopathic Hospital were able to reduce or
stop conventional medication following homeopathic treatment.
32
Basic Science
•
Laboratory research has obtained evidence that water may retain information about
homeopathically-prepared solutes.
33-35
•
Additional laboratory studies have shown that homeopathic dilutions can exert biological
eects
e.g. 36-38
•
Integration of homeopathy with conventional treatment is associated with better clinical
outcomes for similar or lower costs.
