[Objective] In this study, we retrospectively investigated the efficacy of Kampo medicine for refractory acne patients with standard therapy in Japan.
[Patients] Two hundred and thirty nine patients with inflammatory acne completed the study. Six Patients discontinued their systemic treatment because of adverse events. The patients included 193 females and 46 males, with a mean age of 26.5 years. They took Kampo medicine three times daily for 3 months, in a manner according to our protocol.
[Result] For females, 163 of 199 patients (82%) were in the KUOKETSUZAI Group taking medicines such as keisibukuryogankayokuinin, tokishakuyakusan, tokakujyokito, and kamishoyosan. Here, 124 of 163 patients (76%) had a significant decrease in new and inflammatory eruptions after taking the Kampo medicines alone or in combinations with other KUOKETSUZAI medicines. Fourteen of 19 patients (74%) took seijobofuto, of which 6 of 7 females (86%), and 1 of 3 males (33%) had decreased acne eruptions. Also in KUOKETSUZAI group, significant efficacy was shown in females over 21 years of age on combinations. For males, 18 of 23 patients (78%) taking keigairengyoto and 14 of 20 patients (70%) taking seijobofuto, also had decreased inflammatory acne eruptions.
[Conclusion] Kampo medicines exhibit significant efficacy for the treatment of the refractory acne.

In general, keishikashakuyakuto or shokenchuto is used to treat abdominal pain. We experienced 2 cases that kanbakutaisoto were effective in treating abdominal pain, however keishikashakuyakuto and shokenchuto did not have any favorable effect on these cases. Case 1 : A 17-year-old female who consulted us because of abdominal distension and pain. We treated her with keishikashakuyakuto and shokenchuto, but they had no effect on her. As the abdominal pain was increased by anxiety, we prescribed for kanbakutaisoto to her and her symptoms disappeared after one and half months. Case 2 : A 13-year-old male who visited our clinic complaining of upper abdominal pain. He was treated with shokenchuto, but it had no favorable effect. As we knew that he had some anxiety over his club activities and school life, we changed the prescription to kanbakutaisoto, and he recovered after about 1 month. When keishikashakuyakuto or shokenchuto has no effect against abdominal pain, we posit that kanbakutaisoto is useful for the symptom if the patient has psychological problems.
