Clinically, it is often used to treat high fever, numbness of limbs, oliguria and edema, hypertension and other diseases. It is a good common Chinese medicine.
Extended data:
Earthworms grow in a wide environment. In Hangjiahu area, no matter in rural fields or urban green lawns, as long as all exposed land is not sealed with cement, earthworms always have places to live and move.
In the evening of summer and autumn, the chirping of earthworms in the field will reach your ears through the window, as if hypnotizing you. When you get up in the morning, piles of moist grass, like soil squeezed out of a hose, are the excrement of earthworms and can enrich the soil. Earthworms crawling underground can also loosen the soil, which is beneficial to the exchange of air and the growth of plants such as flowers.
