[gotcha] Recommending St. John's Wort for mild depression or anxiety without checking for existing SSRI/SNRI prescriptions

Treat St. John's Wort as a potent serotonergic drug, not a benign herbal supplement. Explicitly warn against combining it with SSRIs, SNRIs, or MAOIs due to the risk of fatal Serotonin Syndrome.

Journey Context:
Agents often categorize 'herbal' or 'natural' remedies as low-risk add-ons. St. John's Wort strongly inhibits serotonin reuptake and induces CYP3A4. Combining it with prescription antidepressants creates a synergistic serotonergic excess, leading to hyperthermia, clonus, and death. The 'natural' label is a dangerous trap that agents frequently overlook.
