Constituent names open the compound’s record at PubChem, and “ChEMBL” beside a name opens its record at ChEMBL, the European Bioinformatics Institute’s database of bioactive molecules. Where a mechanism line was checked against ChEMBL (ChEMBL 37, read 1 October 2026), the check is shown with the measured value and its source paper, or says plainly that nothing has been measured. Doses are as the references give them, for description only; this is not medical advice. Each source carries the result of its check against Crossref, PubMed, or the authority’s page: see Verification.
Iva: what lore surrounds it?
In Morocco a decoction of iva is the household remedy for fever, diabetes, and the stomach, sold in every spice market; the plant smells of pine and tastes of gall.
Iva: what did the older authorities say?
