Therapeutic effects of Ginkgo beloba leaf preparations on psoriasis were studied. Eight patients with psoriasis were attended to the study. Psoriasis area and severity index (PASI) scores of the patients were 12 or more, and the surface of the eczema area was more than 10%. These patients have been regularly or irregularly used steroids. All the patients stopped to use steroids before the start of Chinese medicine treatments. Patients were divided into groups A and B. Group A was 3 case and they have been treated for more than six months with general traditional Chinese medicines other than ginkgo leaves. Group B was 8 cases and they have been treated with the general traditional Chinese medicine plus oral Ginkgo leaf preparations 80 mg × 3/day for more than six months. After 12 weeks and 52 weeks, we evaluated the therapeutic effects by the improvement of PASI points of both groups. After 12 weeks, there was 1 case whose PASI improved to 25% in group A and 6 cases (75%) in group B. After 52 weeks, average of improvement of group A was 50% and that of group B was 82.5%. Ginkgo leaf preparation showed possibly curative effects on the treatment of psoriasis. And we have not found obvious side effects on blood biochemical analyses such as liver and kidney function and on others.
