Possible positive health effects from tea consumption have been confirmed by many studies. The most useful are the least processed types of tea - green and white, as well as various herbal teas (infusions).
Herbal tea, or broth - is a herbal infusion not from the leaves of a tea bush. The infusion can be made from fresh or dried flowers, leaves, seeds and roots. Usually parts of plants are poured with boiling water and infused for several minutes. There are many varieties of herbal tea.
Herbal plants are grown for culinary, medicinal, and in some cases even spiritual needs. Green leaf parts of a plant are usually used. The general use of herbs for tea differs from culinary herbs and medicinal plants. Medicinal herbs can be shrubs or woody plants, while culinary herbs are not woody plants. On the other hand, spices and seeds, berries, bark, roots, fruits and other parts of the plant are also left in some cases, so all of them, as well as any edible fruit or vegetables, can be considered "herbs" in the medicinal sense.
White tea is a tea made from fresh buds and young leaves of the Camellia Sinensis plant (tea leaf). The leaves are steam processed or fried to inactivate the oxidation, and then they are dried. White tea retains a high concentration of catechins, which are present in fresh tea leaves.
The kidneys can also be protected from direct sunlight during growth, in order to reduce the formation of chlorophyll. To produce white tea, small buds are used, covered with silvery hairs, which give white shoots to young shoots.
There are many varieties of tea, the most popular of which are Da Bai (Large White), Xiao Bai (Small White), Narcissus and Chaicha bushes. White tea is exposed to steam and dried almost immediately after harvest (sometimes even before harvesting).
Green tea is made from more mature tea leaves than white tea, and can first be dried before it is steamed or roasted. Although green tea is rich in catechins, it has fewer beneficial substances than white tea. Although also undergoes minimal oxidation during processing.
