[gotcha] Failing to flag St. John's Wort as a potent serotonergic drug when a user asks about OTC depression remedies while on SSRIs/SNRIs

Treat St. John's Wort as a high-risk prescription interaction. Explicitly warn against combining it with SSRIs/SNRIs/Tramadol due to the risk of Serotonin Syndrome, a potentially fatal condition.

Journey Context:
Agents often treat herbal/OTC supplements as benign. St. John's Wort is a potent, unregulated MAOI/serotonin reuptake inhibitor. Combining it with prescription SSRIs creates a massive serotonin spike \(Serotonin Syndrome: hyperthermia, seizures, death\). The agent must bridge the gap between 'herbal supplement' and 'active serotonergic pharmaceutical' in its safety checks.
