Revised October 1, 2026: An older authority added from a text read in full. Version 1, first published September 25, 2026.

Caution. Hazardous in some form or dose; see the modern assessment below.

Bryony: what did Canale use it for?

Its root in the cockerel and the oil; dried and worn on the neck, “it hinders every hex, as Gordonius attests” (chs. 6, 9–10; note XLVIII).

Bryony: what does modern science say?

A violent purgative and poisonous; about fifteen berries are reported as lethal to a child and forty to an adult. The amulet use drew on its mandrake-like root.

Bryony: is it poisonous?

Yes, in some form or dose. Its poisoning is gastrointestinal irritants: Thirty minutes to three hours: the short latency is reassuring, since the deadly syndromes come later. Historical description, not medical advice; in a poisoning, call a poison centre.

Pharmacognosy & Toxicology

Constituents
Mechanism
The cucurbitacins are violent irritants of the gut.
Toxic dose
Forty berries have killed a child; the root, mistaken for mandrake, purges to collapse.
Syndrome
Gastrointestinal irritants
Standing
No medicinal use.

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.

Bryony: what lore surrounds it?

The “English mandrake”: its great forked root was carved into little men and sold as the true mandrake to the credulous (see Mandrake).

Bryony: what did the older authorities say?

Pliny
Calls it the white vine, ampeloleuce to the Greeks, with jointed climbing twigs, leaves jagged like the vine’s, and a root “large and white, and very like a radish at first”; it draws out splintered bones, disperses gatherings, works as an emmenagogue and diuretic, goes into an electuary for asthma, and taken thirty days together in doses of three oboli “has the effect of reducing the spleen”; bands of white vine were also tied round hives to keep bees from flight.
