Question

Why do our mouth start watering nby hearing the word tamarind

Answer 1

${ \sf {\underline { \orange{Explanation:}}}}$

When we eat sour foods like lemon or sour candies, our mouth starts producing a lot more saliva to dilute the sourness in our mouth.

So, our brain always associates mouth-watering with sour food because every time we take these food, our salivary glands kick into overdrive and produce more saliva than usual.
