Pharmacognosy & Toxicology
- Constituents
- Mechanism
- The pectin and tannins bind a loose stool, which is the quince jelly for fluxes; the seed mucilage, quince gum, soothes the throat and was once the hair-setting lotion. A quince syrup matched the drug in a trial of reflux in children (Zohalinezhad, 2015).
- Toxic dose
- A food; the seeds in quantity release cyanide.
- Standing
- A food; the seed mucilage is in the Iranian traditional pharmacopoeia.

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.
Quince: what lore surrounds it?
Marmalade was first made of quinces: the word comes from the Portuguese marmelo.
Some classicists have proposed the quince, not the modern apple, as the golden apple of Greek myth, the fruit of the Judgement of Paris and of the garden of the Hesperides, since the apple familiar today came late to the Mediterranean. It is one candidate among several, with the citron and the orange, and the question remains open.
Quince: what did the older authorities say?
- Plutarch
- Says Solon’s law bade an Athenian bride eat a quince before entering the bridal chamber.
