Back to graph

Two sources, labelled separately on every card. Entries marked "From classical texts" come from public-domain Chinese medical classics; herbs are listed without dosages and compositions follow the common editions. Entries marked "Machine-extracted" are derived by a model from BIOSPHERE own-corpus material (formulation library, ingredient dossiers, compliance index, product catalogue). Neither is an efficacy claim or regulatory text — regulatory and safety conclusions follow the official texts and third-party test reports.
