Is there any blue tea in the world? 5

After gynostemma is made into tea, it is dark green and slime-blue, but the brewed tea is not blue.

Gynostemma is a plant of the genus Gynostemma in the Cucurbitaceae family. It has been identified in 13 species in the world and 11 in China. Gynostemma and plum (Vitis vinifera) grown in the field are similar in plant morphology.

Fresh gynostemma is a perennial herbaceous vine, the stem is slender, 1-3 meters, the cross-section is pentagonal or polygonal, tendrils are born in the leaf axils, the leaf color is dark green, compound leaves, oval leaflets 5-7 petals, with small petioles, the leaves are shrunken, easily broken, the edges are serrate, panicles, 8 20 cm long, fruit bulb-like florets, 5 6 cm in diameter, black after maturity, slightly fragrant, slightly bitter. In folk, gynostemma is used for cough, phlegm asthma, chronic bronchitis, infectious hepatitis and other diseases. Since 1974, Japanese scholars have isolated more than 50 kinds of saponins from this plant, of which 4 are exactly the same structure as ginsenosides, and 11 are similar.

Since 1984, China has investigated and developed the distribution and resources of gynostemma blue. Studies at home and abroad have consistently shown that gynostemma has pharmacological effects such as inhibiting tumor cell reproduction, anti-fatigue, hepatoprotective, anti-gastric ulcer, and regulating lipid metabolism. In May and August of each year during this period of time is the harvest period, after the stems and leaves are cut together, if there is soil, it should be washed and dried, and then cut into about 5 cm segment-like stems and leaves with a guillotine, processed according to the method of making and roasting green tea, after killing, rolling, deblocking, drying or frying, that is, it becomes the initial product of gynostemma tea, and then refined and shaped, and wrapped into the form of tea bags.

Some gynostemma tea is mixed with about 20 jasmine tea to make its fragrance more harmonious and soft. Its stems and leaves may not contain polyphenol oxidase, so it is not easy to ferment to make black-tea-type gynostemma tea. Green tea-type gynostemma tea, with a fragrant fragrance, taste and slight bitterness, sweet aftertaste, light yellow and clear soup color.

It is known as "Southern Ginseng", so some products are named "Southern Ginseng Tea". According to relevant information, gynostemma does have the effect of nourishing and calming the nerves, and has auxiliary effects on some chronic diseases.
