[gotcha] Suggesting St. John's Wort for mild depression as a natural alternative

Never recommend St. John's Wort without a severe interaction warning. It is a potent CYP3A4 inducer that drastically reduces the efficacy of oral contraceptives, immunosuppressants, and SSRIs \(risking serotonin syndrome\).

Journey Context:
Agents may classify 'natural' supplements as low-risk. St. John's Wort is a massive pharmacokinetic trap. It doesn't just add a mild effect; it alters liver enzymes, silently destroying the efficacy of other critical medications the user might be taking, leading to unintended pregnancy or organ rejection.
