Safety information
Toxicity: Moderate-serious depending on use — delivers pharmacologic L-DOPA: nausea, vomiting, dyskinesias, psychiatric effects, blood-pressure changes; pod trichomes are intensely skin/mucosa irritant (serotonin/mucunain). Variable L-DOPA content makes dosing unpredictable.
Contraindications: Pregnancy/lactation; psychiatric disorders/psychosis; melanoma (L-DOPA caution); cardiovascular disease; concurrent levodopa therapy (additive).
Interactions: Levodopa/carbidopa and other PD drugs (additive — overdose/dyskinesia risk), MAO inhibitors (hypertensive crisis), antihypertensives, antipsychotics/dopamine antagonists, antidiabetics.
Pregnancy & breastfeeding: Avoid (pregnancy/lactation).
Evidence level
Supported by clinical trials in humans.

standardized extract · seed
Part used: seed
Traditional use: Parkinsonism support, aphrodisiac/reproductive tonic, 'vata' disorders
Proposed mechanism: Seeds contain natural L-DOPA (levodopa), dopamine precursor — genuine dopaminergic agent (antiparkinsonian effect and drug-like adverse effects); trichome irritation via serotonin and protease mucunain
Dosage note (descriptive only): PD trials used standardized seed powder titrated to L-DOPA content; L-DOPA varies widely — dosing unpredictable, must be medically supervised; no how-to
Reference only — not a dosage instruction
Associated conditions
Edibility
Edible parts: Seeds/beans eaten as famine/pulse food in some regions ONLY after thorough soaking/boiling/processing to reduce L-DOPA and antinutrients. Raw beans and pod hairs are hazardous.
Toxic lookalike warning
Pod trichomes cause severe itching; unprocessed beans carry pharmacologically active L-DOPA — not a casual edible.
Nutritional notes
High-protein legume; also contains L-DOPA, antinutrients (requires processing).
