Experimental Application of Jiin-koka-to to Cases of Bronchial Asthma / 日本東洋医学雑誌

ABSTRACT

The source of the herbal mixture named Jiin-koka-to is Wan bing hui chun. Jiin-koka-to has been used mainly as a decoction for the treatment of bronchitis and tuberculosis. The cases of bronchial asthma treated with Jiin-koka-to in this report had similar symptoms abnormal sensations in the throat and irritation. We investigated the efficacy of Jiin-koka-to in 11 asthma patients having both symptoms. Improvements were observed in all patients; these improvements included reduction of peripheral eosinophil count and serum IgE, loss in quantity of prednisolone, increment of peak expiratory flow rate, and cessation or decrease of asthma attacks. Thus, it is possible that Jiin-koka-to is a controller rather than a reliever in the treatment of bronchial asthma. Abnormal sensations in the throat and irritation might be one of the indications for Jiin-koka-to.
