Including many kind of herbal tea, an indispensable staple in the tea culture of Vietnamese people. The use of herbal tea has been shown to have many medicinal uses.
Drinking herbal tea properly can help quench thirst, aid digestion, avoid sleepiness, stimulate kidney function, help clear the mind, dispel sleepiness. Myxopyrum Smilacifolium leaves are a precious specialty of the Northwestern mountains and forests. It also has many valuable effects on health. The leaves are also shown to contain compounds belonging to the group of alkaloids, glycosides, tannins, phenols, saponins, terpenoids, carbohydrates, vegetable oils, steroids, flavonoids, anthropoids, and amino acids.
The use of Myxopyrum Smilacifolium leaves with some other herbs to produce tea bags will bring convenience and many good medicinal properties to consumers. Moreover, it helps consumers to have more choices in buying, improve efficiency, and contribute to popularizing products from the leaves of the Myxopyrum smilacifolium tree.

Research rationale In the period of industrialization and modernization of the country, continuous economic and scientific development has contributed to improving the quality of life.
Life is getting higher and higher and the need to choose healthy, clean food is being concerned with society when food safety is an urgent issue. Therefore, the use of natural products that are good for health is favored by consumers. Currently, in Vietnam as well as in the world, the trend of using medicinal plants of natural origin is increasing. In which tea is a familiar drink of Vietnamese people in particular as well as East Asians in general, it has cultural characteristics of each region.
Tea is used all over the world, and is considered a global beverage. Tea originates from the Asian region, mainly the southwestern region of China. The use of tea has been shown by the medical world to have a lot of healing power. Drinking tea properly helps to quench your thirst as well as digestion, avoid drowsiness, stimulate kidney function, enhance eyesight, help clear mind, and dispel drowsiness.
Along with the development of society, tea products also have many changes to better suit the increasing consumer demand of people. Ingredients for tea processing in addition to the fresh tea leaves also have teabags. Instant tea is more popular because of its convenience such as instant tea, filter bag tea, bottled tea,…Filter bag tea is a favorite item in the market but has great growth potential. Through the process of learning, it can be seen that Myxopyrum smilacifolium leaves are a precious herbal of the Northwestern Mountains.
The leaves of Myxopyrum smilacifolium have also been shown to contain compounds belonging to the group of alkaloids, glycosides, tannins, phenols, saponins, terpenoids, carbohydrates, vegetable oils, steroids, flavonoids, anthracoid and amino acids [2], [8]. It can be seen that the use of Myxopyrum smilacifolium leaves with some other herbs to produce tea bags can bring convenience and many good medicinal properties to consumers. At the same time, it helps consumers to have more choices in buying, improve efficiency, and contribute to popularizing products 3 from the leaves of Myxopyrum smilacifolium tree. Stemming from the above problems, I conducted the project "Research on tea bag production process made from Myxopyrum smilacifolium leaves".
Overall objectives Research to build the production process of tea bags made from Myxopyrum smilacifolium leaves to create high-quality tea products, bring economic efficiency, contribute to diversifying tea products in the market, and improving income for growers.
