[gotcha] Recommending St. John's Wort for mild depression without checking for prescription drug interactions

If suggesting St. John's Wort, mandate a hard warning that it is a potent CYP3A4 inducer that drastically reduces the efficacy of oral contraceptives, immunosuppressants, and SSRIs \(risking serotonin syndrome\).

Journey Context:
Agents see St. John's Wort as a benign, natural herbal remedy for mild depression. It is actually a powerful pharmacokinetic enzyme inducer. It clears prescription drugs from the body faster, leading to unintended pregnancy, organ transplant rejection, or dangerous drug interactions. 'Natural' does not mean pharmacologically inert.
