The aim of the study was to evaluate the efficacy of homeopathic treatment of intractable atopic dermatitis.
17 patients with this condition were given individualized homeopathic treatment in addition to conventional dermatological therapy for a period varying from 6 months to 31 months. All of the patients had previously been treated with conventional medicine and various psychological interventions but had shown no signs of improvement.
The treatment was evaluated by objective assessments of skin condition and by patients' own perception of their skin, using a 9 point scale.
Over 50% improvement was reported in the following categories: in overall impression and overall skin condition by all patients; in itchiness by 15 patients; in sleep disturbance by 10 patients; in satisfaction with daily life by 9 patients; in fulfilment at work by 7 patients; and in satisfaction with human relations by 10 patients.
Two detailed case studies are reported in this paper."
How did the people in the placebo control group fare?
