Abstract
The frequency of the simultanous use of Kampo drugs was investigated on out-patients' prescriptions at Tohoku university hospital from March to April, 1990.The simultanous use of Kampo drugs themselves (Gappo) comprised 8.6% of Kampo prescriptions. Some of the constitutional crude drugs were overlapped as Grycyrrhizae Radix, Ginseng Radix, Rehmanniae Radix and Ephdrae Herba.
The Kampo prescriptions were inspected by considering the following two points. 1. Similar Kampo drugs like Saiko drugs, 2. Kampo drugs with the same origins.Consequently, about 10% of Gappo fell under each category. It was concluded that it is important to inspect Gappo in the pharmacy.
