Hello, I work in a health center. Many customers here say that the effect of Alexander is unknown. Ailishuang is mainly made from Folium Artemisiae Argyi, Stigma Croci Sativi and Rhizoma Atractylodis. It is mild in nature, bitter in taste, non-toxic and pure in yang, and is mainly used for cervical spondylosis, scapulohumeral periarthritis, hyperosteogeny, lumbar disc herniation, rheumatoid arthritis and so on. Its effective components can penetrate into the skin, and have the effects of promoting blood circulation, relieving pain, removing blood stasis, expelling wind and dispelling cold. And go deep into the epidermis to promote local blood microcirculation, which is fundamentally aimed at human beings.
