The abstract of each source, beneath its citation. For Club members. About the Club or sign in.

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.

Raisins: what lore surrounds it?

Culpeper’s dispensatory gives “Raisons of the Sun” for the breast and the liver; and the small black “raisins of Corinth” gave English its word currant, from the Anglo-French raisins de Corinthe.

Raisins: what did the older authorities say?

Culpeper
Says raisins of the sun “help infirmities of the breast and liver, restore Consumptions, gently clense and move to stool,” and counts them temperate in heat.
The purging decoction
Raisins of the sun stoned, with senna, polypody, ginger, sebestens, and prunes, were boiled into the College’s Decoctum Sennae Gereonis, which Culpeper called “a common Decoction for any purge.”
