Pharmacognosy & Toxicology

Constituents
Mechanism
The sulfides are carminative and antispasmodic in the gut and are excreted by the lungs, which is the old use for hysteria and asthma; in a fumigation they are the smell that was meant to drive the demon out. Given to infants for colic in American folk practice it has caused methaemoglobinaemia (Kelly, 1984).
Toxic dose
Safe as a spice; not for infants.
Standing
A spice of Indian cooking (hing) and in the Ayurvedic and Iranian pharmacopoeias; no European monograph.

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.

Asafoetida: what lore surrounds it?

Its reek is the point: stench to torment the spirit that had taken up residence, as sweetness honored God.

Asafoetida: what did the older authorities say?

Pliny and Strabo
The Persian or Median resin was known in antiquity as a poorer substitute for the silphium of Cyrene, which had grown scarce (see Silphium).
German folk names
Teufelsdreck, “devil’s dung,” for its stench.
