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.

Ox eye: what lore surrounds it?

The ox-eye daisy of the English meadows, Leucanthemum, is the “moon daisy” and the midsummer flower of Saint John, worn against lightning and the devil; if Canale meant that plant, the amulet joins the midsummer herbs.

Ox eye: what did the older authorities say?

Dioscorides
Gives bouphthalmon, the ox-eye, a yellow flower like chamomile, in a cerate to dissolve hard swellings, and says that those who drink it after the bath are rid of the jaundice.
The amulet herbs
Canale strings it with the other strong-smelling composites, the chamomile and the feverfew, which the folk medicine of Italy hung at the neck and burned against the spells of the fascinators.
