A group of researchers at the University o Glasgow and Glasgow Homoeopathic Hospital conducted four studies on people suffering from various respiratory allergies (hay fever, asthma, and perennial allergic rhinitis) In total, they treated 253 patients and found a 28% improvement in visual analogue scores in those given a homoeopathic medicine, as compared with a 3% improvement in patients given a placebo.
In the hay fever study, homoeopathic doses of various flowers that are known to create pollen that initiate hay fever symptoms were used, and in the other studies, the researchers conducted conventional allergy testing to assess what substance each person was most allergic to. The researchers then prescribed the 30 C of this allergic substance. This type of prescribing is named as Homoeopathic immunotherapy.
In addition to this of clinical evidence, an independent group of physicians and scientists evaluated clinical research prior to October 1995. They reviewed 186 studies, 89 of which met their pre-defined criteria for their meta-analysis. They found that on average patients given a homoeopathic medicine were 2.45 times more likely to have experienced a clinically beneficial effect. When reviewing only the highest quality studies and when adjusting for publication bias, the researchers found that subjects given a homoeopathic medicine we still 1.86 times more likely to experience improved health as compared with those given a placebo.
It is the proof for that disproving the saying “Homoeopathic medicines have only placebo effect”
