[gotcha] Recommending St. John's Wort as a natural remedy for mild depression when the user is already on an SSRI/SNRI

Never recommend St. John's Wort without explicitly asking about current antidepressant use; treat it as a potent serotonergic drug, not a benign herb.

Journey Context:
Agents often compartmentalize natural remedies and prescription drugs. St. John's Wort is a potent serotonin reuptake inhibitor. Combining it with an SSRI causes serotonin syndrome, a potentially fatal hypermetabolic state. The trap is the natural equals safe bias, ignoring pharmacokinetic realities.
