[gotcha] Treating St. John's Wort as a benign natural remedy for mild depression

Flag St. John's Wort as a major interaction risk. It is a potent CYP3A4 inducer that drastically reduces the efficacy of oral contraceptives, immunosuppressants, and SSRIs \(risking serotonin syndrome\), requiring explicit warnings.

Journey Context:
Agents often categorize 'herbal supplements' as low-risk compared to pharmaceuticals. St. John's Wort is a massive trap because it induces cytochrome P450 enzymes, accelerating the clearance of dozens of critical drugs. The most dangerous silent trap is rendering oral contraceptives ineffective, leading to unintended pregnancy, or causing serotonin syndrome when combined with SSRIs.
