the body cooling water works by reducing the heatiness in the body not body temperature. Heatiness or "yeat hei" in cantonese doesn't not mean your body is running at a higher temperature. it is just a concept given by the chinese for what i believe to be an ichemical mbalance in the body.

whenever i feel an attack of heatiness on me i take a few bottle and avoid falling sick and if sick due to heatiness it reduces the severity..

hehe take as many as you want.. its pretty expensive lar.. about rm4 for just 500 ml...
