What is the effect and function of grass?

Stretching grass is warm in nature and has the effect of expelling wind and removing dampness, relaxing channels and activating collaterals. We generally use this medicine to treat rheumatism and arthralgia. At the same time, it also has a good relieving effect on pain caused by muscle spasm. Usually, we will use it together with Euonymus bark, saffron or frankincense.
