Interaction
Ashwagandha and thyroid medicines
Ashwagandha can raise thyroid hormone levels. That could add to levothyroxine, or work against antithyroid drugs.
InteractionTurmeric and blood thinners
Two reports describe a raised INR after turmeric in people on warfarin-type blood thinners. Blood thinners leave little margin.
FoodCurd (dahi) at night
Charaka and the Ashtanga Hridaya both say not to eat curd at night. Charaka lists fever, skin disease and jaundice among the illnesses that follow.
ConditionUnderactive thyroid (hypothyroidism): what Ayurveda offers
One small trial found ashwagandha improved mildly raised TSH. No trial we found tested Ayurveda in place of levothyroxine. Do not stop it.
