Stop two weeks before surgery, not two days. That includes dental extraction and any procedure under anaesthetic. The list is longer than most people expect and includes several herbs people do not think of as supplements at all — garlic and ginger among them.
Surgeons and anaesthetists ask about exactly these, and "just some Ayurvedic powder" is not a useful answer to give them.
The List
Stop — bleeding risk (antiplatelet activity)
These make platelets less likely to clump, which adds to surgical bleeding:
- Garlic — the most often implicated in unexpected surgical bleeding
- Ginger (sonth)
- Turmeric
- Tulsi
- Methi
- Chia seeds
- Fish oil, vitamin E, ginkgo, ginseng (not ours, but commonly taken)
Stop — blood sugar
You will be fasting before surgery. Herbs still lowering your glucose during a fast is the wrong combination:
Stop — sedation and anaesthesia
- Ashwagandha — may add to sedatives and anaesthetic agents
Stop — vitamin K, if you are on warfarin
- Alfalfa — directly opposes warfarin. Any change here belongs with the doctor managing your INR, not with you.
Stop — bowel effects
- Triphala · harde · rasayan churna — you do not want a laxative acting during or after a procedure
How Long Before
| Category | Stop |
|---|---|
| Antiplatelet herbs (garlic, ginger, turmeric, tulsi, methi, chia) | 2 weeks |
| Blood sugar herbs | 2 weeks |
| Ashwagandha | 2 weeks |
| Laxative herbs | 1 week |
| External oils and face packs | No need to stop — but not over the surgical site |
Two weeks is the standard because platelets live about 7–10 days. You are waiting for your body to replace the affected ones.
What Does Not Need Stopping
Culinary amounts in cooking are a different matter from concentrated daily supplement doses. A pinch of turmeric in your dal is not the concern; a teaspoon of turmeric powder taken daily as a supplement is.
External use — hair packs, face packs, massage oils — does not need stopping, though avoid applying anything to the area being operated on.
Tell Your Surgeon Anyway
Even if you stopped in time. Many people do not mention herbal supplements because they think of them as food rather than medicine — and then the surgical team is working without the full picture.
Take the actual packets to your pre-operative appointment, or a photo of them. "Some Ayurvedic powders" tells your anaesthetist nothing useful.
If You Did Not Stop in Time
Tell them. Do not stay quiet about it. Surgery is sometimes postponed over this, and that is a far better outcome than unexpected bleeding on the table. The team needs to know what is in your system, not what you intended.
After Surgery
Ask your surgeon when you can restart. It usually depends on wound healing and whether you are on any post-operative blood thinner.
Note that some herbs on this list are traditionally used for recovery — which is precisely why people restart too early. Ask first.
Frequently Asked Questions
Does this apply to dental extraction?
Yes. Dentists ask about blood thinners for exactly this reason.
What about a minor procedure with local anaesthetic?
Still mention it. The bleeding risk is what matters, not the depth of anaesthesia.
Is cooking with garlic and ginger a problem?
Culinary amounts are generally not a concern. Concentrated daily supplement doses are.
Can I take anything for pain afterwards?
Follow your surgeon's instructions. Several herbs here add to the antiplatelet effect of NSAIDs.
How soon can I restart?
Ask your surgeon. It depends on healing and any post-operative medication.
