Edible plantSafety information
Safety information
Toxicity: Low as a spice; high-dose piperine can irritate GI mucosa and significantly alters drug metabolism (the main hazard).
Contraindications: Pregnancy (high medicinal doses — possible effects; culinary amounts acceptable); on narrow-therapeutic-index medications (drug-level changes).
Interactions: Important — piperine inhibits CYP3A4/P-glycoprotein and increases blood levels of many drugs (phenytoin, rifampicin, propranolol, midazolam) and of curcumin. Can raise toxicity risk of co-administered drugs.
Pregnancy & breastfeeding: High medicinal doses possible effects; culinary amounts considered acceptable.
Evidence level
Supported by clinical trials in humans.
Preparations
standardized piperine/powder · fruit
Part used: fruit
Traditional use: respiratory/digestive stimulant, 'yogavahi' bioavailability enhancer, rejuvenative
Proposed mechanism: Piperine inhibits CYP3A4, CYP2C and P-glycoprotein and slows glucuronidation, raising bioavailability of co-administered drugs and nutrients ('yogavahi'); thermogenic and GI-stimulant
Dosage note (descriptive only): Bioavailability studies used piperine in low tens of mg (e.g., ~20 mg co-dosed with curcumin); clinically significant drug interactions
Associated conditions
Edibility
Edible parts: Fruit used as a culinary spice (cooked).
Toxic lookalike warning
Dried long-pepper catkins resemble other Piper/pepper spices; buy identified Pippali; do not substitute unknown dried spikes.
