[gotcha] Treating St. John's Wort as a benign supplement alongside SSRIs/SNRIs

Treat St. John's Wort as a potent serotonergic agent; explicitly warn against combining it with prescription antidepressants due to the risk of fatal serotonin syndrome.

Journey Context:
Users often view herbal supplements as inert, and agents might not flag OTC herbals. St. John's Wort is a potent serotonin reuptake inhibitor and MAOI. Combining it with an SSRI \(e.g., fluoxetine\) can rapidly trigger serotonin syndrome \(hyperthermia, seizures, death\), a silent trap if the agent doesn't actively screen for supplement-drug interactions.
