Study on the School of Traditional Japanese Medicine in the Dose and the Usage Directions of Medication / 日本東洋医学雑誌

ABSTRACT

The authors studied the doses and usage directions for some of the first Traditional Japanese Medicines (TJM) and reached the following conclusions. Since Dosan Manase, who had strong influence on TJM, adopted a method of selecting drugs one by one and refused to use fixed prescriptions, it has been hard to comprehend how much of any drug he administered. As criterion, he showed a half common system of weights. Ekiken Kaibara defined an extremely small dose as 1 ∼ 2 <i>qian</i>. Todo Yoshimasu set around 3 <i>qian</i> as the quantity for one dose, although he calculated that 1 <i>liang</i> was equivalent to about 2 <i>qian</i> (7.5g). Additionally, the Koshogaku school proposed that 1 <i>liang</i> was equivalent to 1.4g.
