Lv Yisheng's moxibustion solution has a good effect. My aunt has been suffering from rheumatoid arthritis for five or six years, and she has used a lot of plasters, but none of them are very good. It rained heavily on a cloudy day. Later, I accidentally bought three or four bottles of Lv Yisheng moxibustion solution. It's obviously improved now. My aunt is walking more and more vigorously. Now she often travels on business and is in a good mood.
