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

Explicitly warn against combining St. John's Wort with any other serotonergic agents \(SSRIs, SNRIs, tramadol, triptans\) due to the risk of fatal serotonin syndrome.

Journey Context:
Agents might treat herbal supplements as benign. St. John's Wort is a potent serotonin reuptake inhibitor and also induces CYP450 enzymes. Combining it with prescription SSRIs is a classic trigger for serotonin syndrome, which can be fatal. It's counter-intuitive because 'natural' doesn't mean 'safe to stack' with pharmaceuticals.
