Old cold legs and rheumatoid arthritis.
Artemisia argyi is a widely used herb in China, which has the functions of expelling wind and removing dampness, promoting blood circulation and dredging collaterals.
The weather is getting colder and colder, and the body may not feel cold yet. But your joints may remind you that your calves are always cold at first, and the problem of knee pain is becoming more and more obvious. As the saying goes, "Teenagers don't know how expensive their knees are, but old people cry when they walk!"
There is an old saying in China that people get old first. Data survey shows that 49.6% of middle-aged and elderly people over 45 years old in China suffer from leg and knee rheumatism in different degrees.
