St. John's Wort is the most interaction-prone botanical — it affects dozens of drugs via CYP enzyme induction. Always inform your prescriber about herbal supplements.
Higher risk for: elderly, those with liver or kidney impairment, polypharmacy (5+ medications), recent medication changes, or those with multiple chronic conditions. Consult your pharmacist for specific risk factors.

Botanicals can affect liver enzymes that process prescription medications, potentially increasing or decreasing drug levels. Watch for: digestive changes, unusual drowsiness or alertness, headache, rash, or any change in how your medication normally works. When to seek emergency help: Severe allergic reaction (difficulty breathing, facial swelling), severe rash, chest pain, irregular heartbeat, or yellowing of skin/eyes.
No urgent discussion needed, but keep your provider informed. Say: "I take Chaga alongside Letrozole — anything I should know?"
