Pharmacognosy & Toxicology
- Constituents
- Mechanism
- A strong astringent with a clove-oil antiseptic: the eugenol is antibacterial and the tannins tighten, which is why it was a gargle and kept moths from linen.
- Toxic dose
- Safe at tea doses.
- Standing
- No monograph; in the German tradition for diarrhoea and mouth inflammation.

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.
Herb bennet: what lore surrounds it?
The blessed herb kept evil away: the Hortus sanitatis of 1491 says that where the root is in the house, the devil can do nothing, and flies from it; its three-lobed leaf and five petals were read as the Trinity and the five wounds.
