Introduction.

Oolong tea is a product made from the leaves, buds, and stems of the Camellia sinensis plant. This is the same plant that is also used to make black tea and green tea. The difference is in the processing. Oolong tea is partially fermented, black tea is fully fermented, and green tea is unfermented.

Oolong tea is used to sharpen thinking skills and improve mental alertness. It is also used to prevent cancer, tooth decay, osteoporosis, and heart disease.

Some people use oolong tea to treat obesity, diabetes, "hardening of the arteries" (atherosclerosis), high cholesterol and skinallergies such as eczema; and to boost the immune system..
