This file provides a description of downloadable files in TM-MC 2.0.

1. Medicinal material
This is a list of medicinal materials provided by TM-MC 2.0 that were listed in the Korean, Chinese, and Japanese pharmacopoeias.
Medicinal materials were distinguished by their scientific names.
Due to differences between pharmacopoeias, a single medicinal material in one pharmacopoeia may map to two medicinal materials in another pharmacopoeia.
