Abstract
|
|
|
Objectives : In 『Treatise on Cold Damage Diseases』, the volume of preparation dosage measured in Hap was 6.5mL.
This study aimed to confirm that a square-inch-spoon, which measures powder preparation dosage, was 1/3 Hap,
and that Jeon-bi was 1/8 square-inch-spoon. Based on these values, this study also aimed to adjust the diameter
of Firmiana-Seed-sized pill preparation, currently known as 6.5mm, so that one square-inch-spoon of powder
preparation creates 16 pills.
Methods : Calculated the ratio between the floor areas of square-inch-spoon and Jeon-bi and measured the ratio
of volume; assumed that powder preparations were stacked as much as possible in the shape of a square pyramid
when scooped comfortably, then calculated the slopes of 1/3 Hap and 1/4 Hap; measured the volumes of powdered
Oryeongsan and Lijungwhan in square-inch-spoon and Jeon-bi; created the powders into Firmiana-Seed-sized
pill preparation; adjusted the diameter of Firmiana Seed so that 16 pills could be created.
Results : Inferring from the floor areas, the volume of square-inch-spoon is 9.2 times that of Jeon-bi; one squareinch-spoon should be 1/3 Hap for the powder to reach its maximum slope of 47° and, according to actual measurement
of powder preparations, reach its maximum volume; when created into Firmiana-Seed-sized pill preparations, one square-inch-spoon should be 1/3 Hap so that approximately 16 pills were created.
Conclusions : One square-inch-spoon of powder preparation was 1/3 Hap(2.17mL), Jeon-bi was 1/8 square-inchspoon(0.27mL), and the diameter of Firmiana-Seed-sized pill preparation was 5.5mm.
