Black pepper: what was it used for?

The hottest of the common spices: for chills, agues, and a cold stomach, and in theriac and the warming powders.

Black pepper: what does modern science say?

Piperine is a mild stimulant of digestion and increases the absorption of some other substances. Piperine stirs the secretions of the stomach and warms by acting on the same nerve receptors as chilli; it also slows the liver’s clearance of other drugs, which is why pepper is put into turmeric capsules and why it can raise the blood levels of some medicines.

Pharmacognosy & Toxicology

Constituents
Mechanism
Piperine activates TRPV1, the chilli receptor, and inhibits the liver’s drug-metabolising enzymes and transporters.
Checked against ChEMBL
  • piperine: Measured, as the entry says (“activates TRPV1”): Transient receptor potential cation channel subfamily V member 1 (human), EC50 3.2 µM, CHEMBL1158557.
  • piperine: No measurement in ChEMBL for “inhibits the liver's drug-metabolising enzymes and transporters” (the only CYP3A4 record is a screen for activators, read as inactive); the line rests on its references.
Toxic dose
No toxicity in food; piperine raises the blood levels of several drugs.
Standing
A food.

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.

Black pepper: what lore surrounds it?

Peppercorns were money: a “peppercorn rent” was once a real payment.

The Pepperers’ Guild of London, recorded in 1180, became the Grocers’ Company; Venice held the trade until Vasco da Gama rounded the Cape in 1498 and answered the Arabs of Calicut that he had come for “Christians and spices.” Dowries were paid in pepper, and a peppercorn rent is a lawful rent to this day.

Black pepper: what did the older authorities say?

Zosimus
Records that Alaric the Goth demanded three thousand pounds of pepper, among his ransom, to spare Rome in 408.
The embalmers of Ramesses II
Put peppercorns into the nostrils of the Pharaoh in 1213 BC, the oldest pepper in the West, carried from India some three thousand miles.
Pliny
Marvels that a thing with nothing to recommend it but its pungency should be fetched from India, and that the spice trade drained the empire of fifty million sesterces a year; long pepper sold at fifteen denarii a pound in Rome, and black at four.
The Periplus
The Greek sailing guide of the first century names Muziris on the Malabar coast as the port where the pepper was loaded for Egypt, and Roman coins by the thousand have been dug up there.
