[gotcha] Classifying St. John's Wort as a benign 'natural' supplement safe to add to existing antidepressant therapy

Flag St. John's Wort as a potent serotonergic agent and CYP450 inducer; combining it with SSRIs/SNRIs risks fatal Serotonin Syndrome.

Journey Context:
'Natural' does not mean 'inert'. St. John's Wort is a pharmacological powerhouse. Agents might suggest it for mild depression, but it induces liver enzymes \(reducing other drug efficacy\) and adds serotonin, creating a toxic interaction with standard prescriptions.
