Melon root: what did Canale use it for?

Powdered, with honeyed wine, as a vomit (ch. 5).

Melon root: what does modern science say?

Melon root is purgative, and in large doses was held a certain emetic. The roots of the cucumber family hold cucurbitacins, bitter triterpenes that irritate the gut and empty it from both ends; the squirting cucumber of the same family is the strongest, and melon root the gentlest of the Greek emetics.

Pharmacognosy & Toxicology

Constituents

cucurbitacins B and Ebitter triterpenoids of the root
elaterin

Mechanism

The root of the melon, like that of its cousin the squirting cucumber, holds cucurbitacins, among the bitterest and most violently emetic substances known, which is the vomit Canale used; they inhibit actin and the JAK–STAT pathway in cells and are studied as anticancer leads.

Toxic dose

A small dose vomits and purges; the squirting cucumber’s elaterium has killed at a few milligrams.

Syndrome

Gastrointestinal irritants

Standing

No use; the cucurbitacins are preclinical.

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.

Melon root: what lore surrounds it?

The melon of the ancients was the pepon, our melon when ripe and a cucumber when green; the root, like the wild cucumber’s, held the bitterness that the sweet flesh lost in cultivation.

Melon root: what did the older authorities say?

Dioscorides: Says the root of the melon, dried and given in honeyed water, provokes vomiting, two drams of it, and that it is milder than the white hellebore; Pliny repeats him.
