Mandrake

Mandragora; Greek mandragoras; Hebrew dudaim

Known today as
Mandragora officinarum and its relatives, of the nightshade family.
Kind
Plant, in 4 older authorities
Constituents
hyoscyamine, scopolamine, atropine
Earliest authority here
Genesis 30 (the Hebrew Bible and the New Testament)
Qualities
FireEarthAirWaterCold in the third degree (Galen); authorities differ on its moisture. What the degrees mean

Caution. Poisonous: tropane alkaloids cause delirium, fever, heart disturbance, and death.

Mandrake: what does modern science say?

Contains the tropane alkaloids hyoscyamine and scopolamine, which account for its sedative, anesthetic, and deliriant effects. Gravely poisonous.

Mandrake: is it poisonous?

Yes, in some form or dose. Poisonous: tropane alkaloids cause delirium, fever, heart disturbance, and death. Its poisoning is tropane (anticholinergic) poisoning: Thirty minutes to a few hours; longer from the skin. Historical description, not medical advice; in a poisoning, call a poison centre.

Pharmacognosy & Toxicology

Constituents
Mechanism
The tropanes block the muscarinic acetylcholine receptors: dry, hot, dilated, delirious.
Checked against ChEMBL
  • atropine: ChEMBL’s curated mechanism: antagonist Muscarinic acetylcholine receptor M1; antagonist Muscarinic acetylcholine receptor M2; antagonist Muscarinic acetylcholine receptor M3.
  • scopolamine: ChEMBL’s curated mechanism: antagonist Muscarinic acetylcholine receptor M1.
Toxic dose
The alkaloid content of the root varies tenfold; a few grams can cause delirium, and deaths are recorded.
Syndrome
Tropane (anticholinergic) poisoning
Standing
No medicinal use. Scopolamine itself is a licensed drug for motion sickness and the secretions of the dying.

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.

Mandrake: what lore surrounds it?

Its forked, manlike root made it the most storied plant of the Middle Ages: it was said to shriek when uprooted and to grow beneath the gallows. Roots were carved and dressed as household spirits, the German Alraune, and Machiavelli made it the title of his comedy La Mandragola (see Machiavelli).

Mandrake: what did the older authorities say?

Genesis 30
Rachel trades a night with Jacob to Leah for the mandrakes Reuben found in the field.
Theophrastus
Records the rites of gathering: draw three circles round it with a sword, and cut facing the west.
Dioscorides
Gives a wine of the root to bring sleep and to deaden pain before cutting or burning in surgery.
Josephus
Tells of a root, baaras, that kills whoever pulls it, and is drawn up by tying a dog to it.

Passes
  • Every sentence read against its sources, in the pass over the remaining 343 entries
  • The Standing line checked against the authority it names (EMA, WHO, FDA, CITES, Commission E)
  • Every dated or regulatory claim checked by category across the database
  • The mechanism read against ChEMBL (ChEMBL 37): curated mechanisms and measured activity

5 cited: 1 read in part, 2 verified against its record, 1 book, seen in reviews, 1 book, not indexed.
Corrections
None were needed.

What was checked, how, and what was found is set out on the Verification page. A checked source is one whose record was found; it does not make the entry medical advice.
