Watermelon is sweet and tasteless, and excessively cold in nature, according to Chinese dietetics. Its target meridians and organs are the Stomach, Heart and Bladder.

Because of its cold nature, its properties include: clarifying heat, refreshing the blood, generating body fluids and moistening dryness.
It is particularly thirst-quenching and refreshing. It is very useful in cases of heatstroke, manifested by fever, thirst, restlessness and a swollen, painful throat.

Its action on the bladder also makes it an excellent diuretic. Last but not least, it significantly reduces the side effects of alcohol.
