Several population-based clinical studies have shown that both green and black teas may help protect against cancer. Early clinical studies suggest that the polyphenols in tea, especially green tea, may play an important role in the prevention of cancer. Researchers also believe that polyphenols help kill cancerous cells and stop them from growing.
The first early harvest of tea, plucked before the first flush, is called shincha. Shincha is made from the youngest new growth leaves, and is plucked from early April to early May. Shincha typically refers to the early harvest of sencha, but can refer to any type of tea plucked early in the season, before the main harvest. Because of the limited quantities in which it is produced, shincha is highly prized and expensive to obtain.
Sejak (세작; 細雀; lit. "thin sparrow"), or dumul-cha (두물차; lit. "second flush tea"), is made of hand-picked leaves plucked after gogu (20–21 April) but before ipha (5–6 May). The tea is also called jakseol (작설; 雀舌; lit. "sparrow tongue") as the tea leaves are plucked when they are about the size of a sparrow's tongue. The ideal steeping temperature for sejak tea is 60–70 °C (140–158 °F).
Studies on green tea’s impact on cancer have been mixed. But green tea is known to aid healthy cells in all stages of growth. There are some clues that green tea may help destroy cancer cells, but that research is still in its early stages, so you shouldn’t count on green tea to prevent cancer. In fact, the National Cancer Institute's web site says it "does not recommend for or against the use of tea to reduce the risk of any type of cancer."
Green tea is the best cure for particularly savage hangovers and fatigue caused by the consumption of alcoholic beverages and lack of sleep. Start your hangover with a large cup of green tea with lemon, and the hangover will quickly fade to a bad memory. Green tea with lemon juice is a very good and popular remedy to eliminate the exhausting effects of alcohol almost instantly.
It also appears to contain more EGCG. ConsumerLab.com, an independent testing group, tested matcha products in 2015 and found that matcha provided 17 mg to 109 mg of EGCG per serving. By comparison, the average brewed green tea provides 25 to 86 mg per serving. While matcha powders contained more catechins per gram than brewed green tea, it was substantially more expensive: The lowest cost matcha powder was available at the time for $2.31 for 200mg of EGCG, compared to 27 cents for the same amount from brewed green tea. Compared to the powders, matcha in tea bags provides significantly less EGCG.
The alpha hydroxy acid and zinc in this red tea are very good for the skin. You can also try applying some rooibos tea powder directly to the skin to relieve acne, pimples, sunburn or related skin conditions. Alpha-hydroxy acids can reduce the signs of wrinkles and other premature aging symptoms but they are rarely found in natural products. They are found in chemical peels, which revitalize the skin and leave it fresh and invigorated with a healthy glow. However, there has been some controversy about commercial uses of alpha hydroxy acid, so it is always better to get it from a natural source, like red rooibos tea.
Usucha, or thin tea, is prepared with approximately 1.75 grams (amounting to 1.5 heaping chashaku scoop, or about half a teaspoon) of matcha and approximately 75 ml (2.5 oz) of hot water per serving, which can be whisked to produce froth or not, according to the drinker's preference (or to the traditions of the particular school of tea). Usucha creates a lighter and slightly more bitter tea.

Rooibos tea can be useful for small children who suffer from colic or stomach pain. You may add some sweetened milk to farm direct red rooibos tea to improve the flavor and make it more palatable. This is actually why rooibos tea is a well-known health aid. Many South African women claimed that this plant was very soothing for their colicky infant.
Believe it or not, green tea also helps people lose weight by enhancing the rate of metabolism, thereby promoting a faster consumption of the fat storage of the body. Recently, green tea has replaced many other beverages as it helps in weight loss. Drink a cup or two of green tea every morning and you are bound to lose a few pounds of excess weight over a week or so.
Green tea contains significant amounts of flavonoids, antioxidants that protect against heart disease by slowing the breakdown of LDL cholesterol, preventing blood clots, and improving blood vessel function. The benefits of green tea also include associations with lower cholesterol and lower rates of artery blockages. People who drink a cup or two a day have a 46 percent lower risk of developing narrowed arteries. Upping that to three cups a day lowers the risk of having a heart attack by 43 percent and of dying from a heart attack by 70 percent. It can even help prevent a second heart attack. In a study of 1,900 patients recovering from heart attacks at Beth Israel Deaconess Medical Center in Boston, the death rate among patients who drank at least two cups of tea a day was 44 percent lower than among non-tea drinkers.
