Herbological studies of Coptidis rhizoma (Part 2): on the old Japanese name of Coptis japonica makino.
The rhizome of Coptis plant of the family ranunculaceae has been used in traditional Chinese medicine as a crude drug (Huanglian in present Chinese). In Japan, the rhizome of Coptis japonica Makino (the botanical name of which is "Ohren" in modern Japanese) has been utilized as a crude drug since the Nara era. The Japanese name in those days was "Kakumakusa based on descriptions in old books written in the Heian era. It changed to "Kakumikusa" early in the Edo era, and then changed again to Kakumakusa later in the Edo era. Through this herbological study, it was conjectured as follows: The resemblance between Chinese characters (or MA) and (or MI) in cursive style caused mis-copying of the character. After the "Honzo-wamyo, written in the Heian era, was revised in the late Edo era, and on which the name was accurately written as Kakumakusa, the mistake was corrected.
