Hello,
Excessive thirst is common after eating salty
and spicy food.This is because salt which contains sodium
and chloride,the body uses water to flush extra sodium away and hence one feels thirsty.
There is no proven remedy as such which can be a remedy for excessive thirst except water ,but it has been found that adding a wedge of lemon or orange peel, a sprig of mint or fresh coriander to water helps a lot.
