Taking the whole herb with roots as medicine, it is cold in nature, pungent in taste, sweating and rash, clearing away heat and promoting diuresis, and is mainly used for treating exogenous fever, measles and edema.

Extended data:

The outbreak of duckweed is mainly due to eutrophication, that is, the content of nitrogen, phosphorus and other nutrients in water is too high. With the increase of temperature, duckweed will gather in a large area when the temperature and pH are suitable.

In view of the reasons of duckweed outbreak and the disadvantages in duckweed control, the unique Eama- 1 1 series duckweed biological algaecide combined with BPA-10/7 series microbial water purifier was used to rapidly consume nitrogen and phosphorus nutrients in the water body, thus reducing the eutrophication of the water body, improving the water quality and restoring the balance of the water ecosystem, and finally achieving the goal.
