Are tamarind seeds poisonous?

Normally, tamarind seeds are not poisonous. However, tamarind seeds can turn fatal if they are cooked or stored in unhygienic conditions. Tamarind seeds are also known to cause Weaver’s Cough or a sense of constriction of the chest if consumed in the powdered form. Furthermore, tamarind seeds pose a negative impact on lungs and can cause respiratory issues if taken in excess quantity.

I gulped tamarind seeds yesterday, so does it affect on my body???

No it will not affect you anymore, drink excess water to remove it through stool
