Guggul 4 interactions
Caution
+ Thyroid medicine: May raise thyroid hormone levels, adding to medicine effect. Source
Caution
+ Blood thinners: May slightly slow clotting, adding to bleeding risk. Source

Caution
+ Diabetes medicine: May have a mild blood-sugar-lowering effect that can add to diabetes medicine.
Caution
+ Liver-affecting medicine: Indian case series have linked prolonged/high-dose use to liver injury; combining with other liver-stressing medicine raises this risk. Source
Turmeric / Curcumin 2 interactions
Avoid
+ Blood thinners: Curcumin’s blood-thinning activity can raise INR with warfarin โ€” documented case reports of dangerously high INR at high supplement doses. Source
Caution
+ Diabetes medicine: May reduce blood glucose, adding to medicine effect. Source
Garlic 1 interaction
Caution
+ Blood thinners: Concentrated supplements can add to bleeding risk; normal culinary use is generally safe. Source
Ginger 2 interactions
Caution
+ Blood thinners: May mildly reduce platelet clumping; caution advised, especially before surgery. Source
Caution
+ Diabetes medicine: May increase insulin and lower blood glucose, adding to medicine effect.
Licorice / Yashtimadhu 3 interactions
Avoid
+ Diuretics: Causes sodium retention and potassium loss โ€” can drop potassium to dangerous levels with diuretics. Source
Avoid
+ Digoxin: Potassium loss sensitizes the heart to Digoxin, raising toxicity and dangerous rhythm-change risk. Source
Avoid
+ Blood pressure medicine: Sodium/water retention directly counteracts blood pressure medicine. Source
Fenugreek / Methi 2 interactions
Caution
+ Diabetes medicine: Slows sugar absorption, raising hypoglycemia risk when combined. Source
Caution
+ Blood thinners: Mild blood-thinning effect can add to anticoagulant medicine. Source
Brahmi 2 interactions
Caution
+ Thyroid medicine: Animal research shows it can raise T4 levels; monitor if combined. Source
Caution
+ Sedatives: May add to the calming effect, increasing drowsiness. Source
Tulsi / Holy Basil 2 interactions
Caution
+ Blood thinners: May slow clotting slightly, adding to bleeding risk. Source
Caution
+ Thyroid medicine: May reduce medicine effectiveness; monitor thyroid levels if combined. Source
Cinnamon / Dalchini 4 interactions
Caution
+ Diabetes medicine: Cassia cinnamon can lower blood sugar, raising hypoglycemia risk. Source
Caution
+ Blood thinners: Coumarin content can add to bleeding risk; Ceylon cinnamon is lower risk. Source
Avoid
+ Liver-affecting medicine: High-dose coumarin can stress the liver โ€” rated a major interaction in clinical references. Source
Caution
+ Statins: Reports of interaction with cholesterol-lowering statin medicine. Source
Arjuna 3 interactions
Caution
+ Blood pressure medicine: Early evidence of BP-lowering activity could add to medicine effect. Source
Caution
+ Blood thinners: Shown antiplatelet activity in studies, could add to bleeding risk. Source
Caution
+ Digoxin: Cardiac-stimulant properties; evidence combining with cardiac glycosides is limited, so supervision is advised. Source
Neem 3 interactions
Caution
+ Diabetes medicine: May lower blood sugar, raising hypoglycemia risk. Source
Caution
+ Immunosuppressants: May stimulate immunity, theoretically working against immune-suppressing medicine. Source
Caution
+ Lithium: May reduce the body’s ability to clear lithium, potentially raising blood levels. Source

Frequently Asked Questions

Common questions people ask the Ayurvedic Herb Interaction Checker:

Can I take Ashwagandha with thyroid medicine like Levothyroxine?

Use caution. Ashwagandha may raise thyroid hormone levels in the body and can add to the effect of thyroid replacement medicine, so thyroid levels should be monitored by a doctor if combined.

Is it safe to drink Karela juice while taking Metformin or insulin?

Not without medical supervision. Karela contains insulin-like compounds that lower blood sugar. Combined with diabetes medicine, this can cause dangerously low blood sugar.

Does Turmeric or Curcumin interact with blood thinners?

Yes. Curcumin has natural blood-thinning activity and can increase bleeding risk when combined with anticoagulants like Warfarin, especially at high supplement doses.

Does homeopathy interact with conventional medicine?

Classical homeopathic dilutions above 6C contain no measurable original substance, so chemical drug interactions are not expected. The main real-world risk is delaying necessary conventional treatment, not a chemical interaction.
