Six public APIs, no keys and no paywall. Queries are scoped to title and abstract rather than full text, because a full-text hit on Curcuma in a reference list is not evidence of anything. Everything retrieved is then passed through an interaction-vocabulary gate: a paper is admitted only if it actually describes an interaction, not merely because it names a plant and a drug in the same abstract. What survives is ranked against an eight-level evidence hierarchy, so a randomised trial outranks a review that cites it.
Enzyme-inducing botanicals lower plasma anticonvulsant concentrations, while GABAergic constituents add sedation and a few (thujone, camphor, beta-asarone, pinene-rich oils) are directly proconvulsant and lower seizure threshold.
Expected clinically: Breakthrough seizures, status epilepticus, or additive sedation and ataxia.
