[gotcha] Recommending St. John's Wort for mild depression without checking for concurrent SSRI/SNRI use

Always explicitly warn that St. John's Wort cannot be combined with prescription antidepressants \(SSRIs/SNRIs\) due to the risk of fatal Serotonin Syndrome.

Journey Context:
Agents might see St. John's Wort as a benign, natural alternative for mild depression. The trap is its mechanism: it is a potent serotonin reuptake inhibitor and MAOI. Combining it with pharmaceutical SSRIs leads to massive serotonin accumulation, causing hyperthermia, seizures, and death. The NHS heavily warns against this specific interaction.
