• Homœopathic treatment of mosquito bites

Homœopathic treatment of mosquito bites

A randomised, placebo controlled clinical trial was recently conducted to examine the efficacy of a homœopathic after-bite gel in providing symptomatic relief of mosquito bites. Sixty eight healthy volunteers were bitten under laboratory conditions by Aedes aegypti mosquitoes at three spots on the forearm. One bite was treated with the homœopathic after-bite gel, another bite with a placebo gel which was identical in appearance and smell to the homœopathic after-bite gel, and the third bite remained untreated and was used as a control. 

Immediately after the bites and at 1, 3, 6, 26 and 31 hours afterwards, the length and width of the erythema were measured with a calliper, and photographs were also taken of the bite sites. The extent of itching was assessed by each patient using with a verbal analogue scale. 

The results showed that the bites treated with the homœopathic treatment group fared significantly better than the placebo and control groups. The average (median) total erythema was 10.500 mm2*h in the homœopathic group, 12.900 mm2*h in the placebo group and 13.300 mm2*h in the control group.

After pooling the data of a very similar previous pilot study involving 15 people and the
present study ( total number of subjects = 83), the homœopathic after-bite gel was found to be significantly superior to placebo or no treatment. The extent of itching was positively correlated with the area of the erythema, and treatment of mosquito bites with the homœopathic after-bite gel was found to effectively reduce the erythema.
