Before gallbladder surgery or ERCP, how should I report herbs and supplements?
Give the procedure team a full list of medicines, herbs, and supplements, including doses and the last time taken. Ask that team and your prescribers for individual stop-and-restart instructions; do not stop medicines on your own.
In this answer
Tell the procedure team about all prescription medicines, over-the-counter products, herbs, and supplements. Bring each product's name, ingredients if available, dose, schedule, and last time taken. NIDDK's ERCP preparation guide specifically says to discuss prescription and over-the-counter medicines, vitamins, and supplements with your doctor and ask whether your own medicines need adjustment. The team—not a fixed rule from a web page—should tell you what to stop, continue, or restart for your procedure. Do not stop a prescribed medicine on your own, and do not assume a product is safe around anesthesia just because it is called “natural.”
Why a complete list matters
Products sold as supplements differ in ingredients and amounts. Some can interact with medicines or pose risks around surgery, including effects on bleeding or the response to anesthesia. This is a reason to disclose what you take, not proof that every herb causes a particular complication. Include decoctions, pills, powders, and products bought online, as well as prescribed medicines and common pain relievers. A package photograph or ingredient list can help identify an unfamiliar product.
If you take an anticoagulant or another medicine with an important reason for continued treatment, make sure its prescriber and the procedure team agree on any interruption and restart. An urgent procedure may leave no time to adjust beforehand; still tell the team what you took recently. If two clinicians give conflicting advice, show both the same current list and ask them to reconcile it.
Give both teams the procedure details
Tell your Korean-medicine clinician whether you are having ERCP or gallbladder surgery, the date, the hospital's fasting and medicine instructions, and whether there is an active infection or blocked duct. Discussion of eating, nausea, stools, sleep, and energy belongs to a stable period and must not displace preparation or follow-up ordered by the procedure team. No evidence cited here establishes that herbs dissolve a stone or replace ERCP or surgery.
There is no single safe “stop all herbs X days before” or “restart the next day” rule for every product and person. The procedure, product, other medicines, and individual risks determine instructions. After the procedure, follow the discharge plan for medicines and food before restarting anything. Fever, increasing abdominal pain, jaundice, or vomiting needs prompt contact with the procedure team or urgent assessment, not an attempt to adjust supplements at home.
A practical handover checklist
Bring the names or photographs of products; ingredients, doses, frequency, and last doses; your surgery or ERCP appointment and discharge instructions; and contact details for the professionals who prescribe your medicines or herbs. Ask exactly which items to continue, pause, and restart, and who to contact if the schedule changes.
