Abstract:
Kaolin was tested on 180 crude drugs for use as a coloring agent. Eight crude drugs—Atractylodis Rhizoma, Atractylodis Lanceae Rhizoma, Magnoliae Cortex, Asiasari Radix, Pogostemi Herba, Linderae Radix, Citri Leiocarpae Exocarpium and Caryophylli Flos-exhibited coloration. The present results indicate that kaolin can be added as a colorant to crude drugs as a simple method for the distinguishing and identifying the crude drugs in the Kampo pharmacy.
