There are several factors to consider when deciding when to stop ashwagandha before surgery. Typically you should stop herbal supplements 7 to 14 days before your procedure, but timing can vary based on anesthesia type, other medications, and your overall health.

Ashwagandha is a popular herbal supplement often used to reduce stress, boost energy, and support overall well-being.

Possible concerns during surgery:
Bleeding risk
• Some herbs thin the blood or inhibit platelets. While research on ashwagandha's direct impact on clotting is limited, combining it with other blood-thinners (like aspirin or warfarin) raises concerns.
Blood pressure swings
• Anesthesia can lower blood pressure. If ashwagandha also lowers it, you might become hypotensive during surgery.
Sedation and anesthesia interactions
• Ashwagandha may have a calming effect. Adding sedatives or anesthetics on top of that can lead to over-sedation.
Hormonal shifts
• If you have thyroid or adrenal issues, ashwagandha may alter hormone levels, potentially affecting how you respond to anesthesia and recovery.

Speak to your doctor about any serious or life-threatening concerns. If you notice severe symptoms—such as unusual bleeding, chest pain, or difficulty breathing—seek emergency care right away.
Your safety is the top priority. Open communication with your healthcare providers about ashwagandha and surgery risk ensures the best outcome for your procedure and recovery.
