【Literature Discussion】
“Ben Cao Tu Jing”: “Water calamus, there are many in the streams and waters, and the leaves are similar, but the center has no ridges. After harvesting, it is light and empty and has a lot of dregs. It is not as good as stone calamus. It cannot be used as medicine, but it can be smashed. Use oil to apply scabies. Most of the medicines sold in today’s drugstores are mixed with two kinds, and it’s hard to tell them apart.”
“Materia Medica Yanyi”: “Acorus calamus, also known as orchid sun in the world, is born with water, and it will dry when it loses water. Those with dense root joints have a strong smell.”
