Report #102644

[gotcha] Agent treats St John's wort or other herbal supplements as safe because they are natural

Flag that St John's wort can interact with antidepressants, anticoagulants, contraceptives, immunosuppressants, and others; always ask about supplements before giving medication advice.

Journey Context:
Patients often do not report supplements as medicines, and agents omit them from interaction checks. St John's wort is a classic example: it can alter levels or effects of many prescription drugs. The fix is to explicitly include supplements in any medication history and warn against assuming natural equals safe.
