MANUAL_CURATION
via MIM curation (#288)
A named multi-component preparation. Searched CHEBI, NCIT, MeSH, FOODON and ENVO by label and synonym: no term denotes it, and none could -- a preparation is not a substance. Takes the STOCK_SOLUTION convention: a kgmicrobe.ingredient: mint with no parent, because a multi-component mix does not narrow to any single compound (#288).
