Sarsaparilla

Pharmacognosy & Toxicology

Constituents

• sarsasapogenin and smilageninsteroidal sapogenins, from the saponins
• parillin
• sitosterol ChEMBL

Mechanism

The saponins are mildly diuretic and diaphoretic, which with the sweating regime was the whole of the syphilis cure, a disease that remits on its own between stages; nothing in the root acts on the spirochaete. The sapogenins were a starting material for steroid synthesis in the 1940s, and the “testosterone” of bodybuilding supplements is not in the plant.

Toxic dose

Safe; the saponins irritate in excess.

Syndrome

Saponin irritation

Standing

A flavour of root beer; no approved medical use. The German Commission E issued a negative monograph for psoriasis.

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.
