[gotcha] Suggesting St. John's Wort as a natural remedy for mild depression alongside SSRI prescriptions

Never recommend St. John's Wort to a patient already taking SSRIs, SNRIs, or MAOIs. Explicitly warn that combining them causes serotonin syndrome, a potentially fatal condition.

Journey Context:
Agents trained on lifestyle/wellness data often suggest 'natural' supplements like St. John's Wort for depression. The gotcha is that St. John's Wort is a potent serotonin reuptake inhibitor and a CYP450 inducer. Combining it with prescription SSRIs silently stacks serotonin levels, leading to toxicity instead of additive benefit.
