Moyeam is usually grown in Zhang Jiajie, the famous mountain in the region of the Middle Hunan province of China. The generic name comes from the plant Ampelopsis grossedentata, The specific name Ampelopsis grossedentata comes from the plant's growing structure and leaves. The leaves and stems are used to make a herbal tea called Moyeam (China). The product has been popular in China for generations and is now consumed in some other countries. The English name Moyeam is spelled from the Chinese name “茅岩莓”. Moyeam is deciduous woody vine plants.It germinates in Spring and fade in Autumn, no significant difference between primary and secondary roots underground ; Plant stems and leaves are glabrous, cirrus grows, stem diameter is about 0.2 ~ 0.4cm, the largest annual production is in early summer and Autumn is second. General annual growth is 0.7 ~ 0.8m, dorsal leaves in spring are gray, draped white frost. Leaflets is thin papery or herbaceous, long, narrow, oblong, oval or grant needle-shaped, margin coarsely toothed, young stems and leaves has light reddish purple. Knead by hand the leaves and stems would have viscosity and come into the group, and have significant white substance  on the plant surfaces and hands (it is the Dihydromyricetin compounds), chewing it,first feel bitter, astringent, gradually turn sweet.

Production and processing[edit] A Moyeam-infused liqueur and Moyeam tea. The process way of Moyeam plant is handed down from Chinese Tujia minority people 600 years ago, it is plucking, withering,rolling and fermentation. The fresh leaves should be withered within 5 hours to avoid oxidization and losing nutrients. During the rolling step,it produces the distinctive “white frost ”color of Moyeam and enhances the flavor. Unoxidized "white" Moyeam is also produced, but the more demanding production process for white Moyeam (similar to the method by which green tea is produced) makes it more expensive than traditional Moyeam. The taste is slight bitter and following strong sweet, it is the distinctive characteristic of finest tea. Moyeam carries the “white frost” and slightly grassy flavour somewhat different from other common teas in China.[2] Use[edit] In Tujia minority settlements of China, it is common to prepare Moyeam tea in the similar manner as green tea and drink directly because it has the nature sweet taste. The Tujia people who often drink this tea all the years without hypertension, high cholesterol, obesity and cancer.

Nutritional values and chemical composition[edit] Moyeam is rich in flavonoids, the average level in Moyeam plant can reach 40%.This is the highest of all known plant in the world It is becoming more popular with Chinese people, particularly among health-conscious consumers, due to its high level of flavonoids especially Dihydromyricetin.It is nature, no resistance to drugs, no polution and no remain.It has been tested that the Dihydromyricetin flavone has antibiosis, eliminate inflammation, antioxidation, clearing radical, regulate blood sugar and fat, antitumor effects. Accoridng to the test result, Moyeam is also rich in 17 kinds of amino acid and has 14 kinds of micro element, especially Fe, Cu,Mn,Zn are higher, which are essential for our physical health. Health benefits[edit] Moyeam is purported to assist respiratory disease, antibiosis, eliminate inflammation, antioxidation, clearing radical, regulate blood sugar and fat, antitumor.[10] Moyeam tea has been shown to cure respiratory diseases, and some clinical study have been conducted. Outpatient Test 1 Test 70 cases, take 2g/time, 2-3 times/day, brewing with boiling water for about 5 minutes. Every 10 days is a course of treatment,take 1-3 courses.

Outpatient Test 2 Test 20 cases,9 male, 11 female, take 2g/time, 2 times/day, brewing with boiling water for about 5 minutes. Every 10 days is a course of treatment,take 1-3 courses.

There are 40% flavonoids found in Moyeam, and Dihydromyricetin take the 70% percentage in flavonoids, have been known to have cancer and tumor fighting qualities and antioxidant effects. It does not contain the antioxidant Epigallocatechin-3-gallate (EGCG) found in green tea. But the Dihydromyricetin has even better performance compared with the EGCG.Because the hot-resistance of Dihydromyricetin can reach 240℃ and the suitalble PH range is wider than EGCG. Because the high level of Dihydromyricetin, the extract of Dihydromyricetin is of high production and been applied to many fields. Traditional medicinal uses of Moyeam in China include personal care products,cold medicine, pet food. Scientific experiments[edit] The basic chemical composition of Moyeam include water, water extracts, ash, inorganic elements, proteins and amino acids, polyphenols and flavonoids, carbohydrates, vitamins, and other volatile components. Human studies of Moyeam are scarce in scientific literature.[15] Animal studies show that rooibos has potent of curing respiratory disease,immune-modulating ,antioxidant,and protecting liver from alcohol damage. A review found no documentation of adverse side effects of consuming Moyeam tea. It is often claimed that "green"moyeam has a higher Broad-spectrum antibiotic and antioxidant capacity than fully processed Moyeam. However, one study, using two different methods of measuring antioxidant and Broad-spectrum antibioticactivity, found conflicting data, with green Moyeam showing more activity under one measure, and less activity using the other. Because the main active composition is Dihydromyricetin, when rolling the moyeam, the cytoderm is broken and the Dihydromyricetin is released to have function to our physical body. Geographical environment After the 4th century glacier extinction raids, Moyeam only grows in Zhang Jiajie high mountains above sea level 800m to 1500m. The water, air and soil are isolated from contamination; The eruption of crustal movement formed particular red sandstone soil, the soil is rich in nutrients which is very conducive to the formation of flavonoids, vitamins and trace elements in Moyeam plant.Growing in the rational settlements of mysterious Chinese Tujia minority, there is specific sunniness , rainfalls and moist air. Similar plants are also found in other provinces of China, mainly at the south of Changjia River. A few studies also mentioned the growth in south-west Asia countries. But it has been researched that the similar plants do not have the complete and important physiological functions compared with Moyeam. History In 1385, Moyeam was given to the king of Tujia minority as the best present, because it could cure kinds of disease. At that time it was named" Heaven Tea".In 1837 Chinese Qing dynasty，Moyeam was given to the Emperor of China as the present of Tujia minority, the Emperor found the tea had amazing effects for health, so ordered it as the Tea exclusive for Emperor. At present, precious Moyeam is made with the Tujia minority method inherited 600 years ago. It is said only female can inherit this mysterious tea artistry.
