[gotcha] Recommending St. John's Wort as a safe, natural alternative for mild depression

Never suggest St. John's Wort without explicitly warning it induces CYP3A4 and causes severe interactions with SSRIs \(Serotonin Syndrome\) and renders oral contraceptives ineffective.

Journey Context:
Agents might classify 'natural' supplements as low-risk. St. John's Wort is a potent enzyme inducer. If a user is already on an SSRI, adding it can cause fatal serotonin syndrome. If on birth control, it causes breakthrough bleeding and pregnancy. The 'natural' label masks severe pharmacokinetic interactions.
