The 14th edition of the Japanese Pharmacopoeia (JP, Nihon yakkyokuhō) lists 165 herbal ingredients that are used in Kampō medicines. Lots of the Kampō products are routinely tested for heavy metals, purity, and microbial content to eliminate any contamination. Kampō medicines are tested for the levels of key chemical constituents as markers for quality control on every formula. This is carried out from the blending of the raw herbs to the end product according to the ministry's pharmaceutical standards.
