How do you tell if a food or herb is "heaty" or "cooling"?

Answer 1

most of the fruits if in red n yellow flesh r heaty,if in white then cooling.n fact u can feel the difference u w'd drink lots of water cos of thirsty so it's heaty.

Answer 2

We grew up with the knowledge.....anything fried food, mango, durian all heaty.

mangosteen, salt, clear soups all cooling....

ok....let me say it in a more understandable way....anything that dehydrates you is heaty and anything that dont is cooling
