Experts at the Tohoku Agricultural Research Center in Japan have found that a herb called Angelica sinensis has a therapeutic effect because its leaves are rich in antioxidants. Experts actively advocate the cultivation of Angelica sinensis and recommend it to be eaten as a vegetable.
After laboratory analysis, scientists from this agricultural research institution confirmed that the leaves and green and white stems of Angelica sinensis contain more antioxidant ingredients, such as chlorogenic acid, quercetin and so on. The content of chlorogenic acid in edible chrysanthemum is about 50 to 60 milligrams per 100 grams, while in the leaves of Angelica sinensis, the content of chlorogenic acid is as high as 200 to 400 milligrams.
Reactive oxygen species can damage proteins and lipids in the human body, leading to various diseases such as cancer. Antioxidant components reduce the production of reactive oxygen species and thus prevent the occurrence of these diseases.
Angelica sinensis, also known as solitary grass, perennial herb, long in the mountains, its leaves fragrant, stem 2 meters high, tender stem edible, rhizome can be used as medicine, sweating, antipyretic and other effects.

How to prevent early bolting of Angelica sinensis
Angelica is native to alpine mountain area and is a plant with low temperature and long sunshine. In ontogeny, vegetative growth to reproductive growth goes through two stages: vernalization stage (low temperature of 0 ℃) and light stage (long sunshine for more than 12 hours). Therefore, artificial cultivation requires growing seedlings in the first year, harvesting roots for medicine in the second year, and bolting and flowering and fruiting in the third year. However, in production practice, Angelica often bolts and blossoms in June to July in the second year of cultivation, and the bolting rate in normal years is 10%.
