Tokishakuyakusan is well-known to be useful in infertility. We report 3 cases of infertility that resulted in pregnancy and childbirth due to oral administration of tokishakuyakusan after being led to tokishakuyakusan pattern by symptomatic treatment resolving blood stasis or regulating qi. Case 1 was a 39-year-old woman with unexplained infertility. She visited our hospital because of irritability and was initially administered keishibukuryogankayokuinin and yokukansankachinpihange, and then tokishakuyakusan. After a month of treatment, she conceived. Case 2 was a 33-year-old woman who was diagnosed with ovarian dysfunction and received ovarian stimulation. To support infertility therapy she was administered keishibukuryogan, and subsequently, tokishakuyakusan based on her pattern. After 3 months of treatment, she conceived. Case 3 was a 37-year-old woman who was diagnosed with unexplained infertility and was administered kamishoyosan and hochuekkito for premenstrual syndrome at another hospital. She visited our hospital because of sensitivity to cold and fatigability. The previous treatment was discontinued, and she was administered tokishakuyakusan based on her pattern. After 2 months of treatment, she conceived. All 3 patients continued tokishakuyakusan treatment during pregnancy and successfully delivered live babies. These 3 cases initially received other Kampo medicines and then, tokishakuyakusan, according to the changed Kampo medical pattern. It is important to administer tokishakuyakusan to patients with infertility, following administration of appropriate Kampo medicine to correct their imbalance of qi, blood and fluid and after further confirming the abdominal signs suitable for tokishakuyakusan.

De Quervain disease and carpal tunnel syndrome are major problems that occur after delivery. During pregnancy, hormone confusion readily causes inflammation of tendons ;furthermore, overuse of hands during care of other children contributes to symptom onset. We report four cases of de Quervain and carpal tunnel syndrome occurred after delivery. All patients were women, aged 33-­39 years. All patients breast-­fed after birth. One patient was diagnosed with de Quervain disease, two were diagnosed with carpal tunnel syndrome, and one was diagnosed with de Quervain disease accompanied by carpal tunnel syndrome. All patients received tokishakuyakusan ;thereafter, their pain decreased, but slight numbness from the carpal tunnel syndrome remained. Drugs that can be used during breastfeeding are limited ;however, tokishakuyakusan can be prescribed safely and effectively.
