Where are the latest production areas of Agrimonia pilosa? A complete list of its main producing areas
Agrimonia pilosa, also known as tuoli cao, guaxiang cao, laoniujin, langya cao and so on, is a perennial herb of the genus Agrimonia in the rose family. The dried above-ground parts of the plant, with residual roots and impurities removed, washed and dried, can be used as medicine. It has the effects of astringing to stop bleeding, treating malaria, stopping diarrhea, detoxifying and tonifying deficiency. Now let us take a look together at where the production areas of Agrimonia pilosa are!
Where are the production areas of Agrimonia pilosa?
Agrimonia pilosa grows up to 1 m tall. The whole plant has long white hairs. The rhizome is short and often produces 1 or several root buds. The stem is erect. The pinnately compound leaves are alternate. The raceme is terminal. The calyx is obconical. The petals are yellow. The calyx tube thickens and droops when the fruit ripens, with a whorl of erect hooked spines at the top, very much like the head of a red-crowned crane, hence the name Agrimonia pilosa. The flowering and fruiting period is from May to December. The production areas are mainly located in Jiangsu, Zhejiang, Hubei and other places, and it is also produced in other parts of the country.
The production environment of Agrimonia pilosa
Agrimonia pilosa prefers a warm and humid environment. The suitable growth temperature is 20-30°C. It is not strict about soil, but deep, loose and fertile sandy loam is best. For planting, seeds or root division are used for propagation. For spring sowing, it is late March in the south and mid-to-late April in the north. For autumn sowing, it is late September to early October in the south and late October to early November in the north before the ground freezes. Root division propagation can be carried out in both spring and autumn.
