[gotcha] Treating St. John's Wort as a benign 'natural' alternative for depression without interaction warnings

Never recommend St. John's Wort without a severe interaction warning against concurrent use with SSRIs, SNRIs, or MAOIs due to the risk of fatal Serotonin Syndrome, and warn it reduces the efficacy of birth control.

Journey Context:
Agents often index on 'natural/herbal = safer.' St. John's Wort is a potent CYP3A4 inducer and serotonin reuptake inhibitor. Users taking prescribed antidepressants might add it for a 'boost,' leading to serotonin toxicity. It's a classic interaction trap because patients don't report supplements to doctors, and agents might not treat a 'supplement' with the same rigor as a drug.
