Hello! Dredging meridians is already a health care method, so I don't know what your previous question means, so I don't know how to answer you. If you want to ask how to dredge the meridians, you can use scraping and hand pushing.

When it is cold, your joints will ache. It is estimated that it should be caused by cold and dampness pathogens blocking meridians. It is suggested that you can find two meridians to dredge up the exogenous diseases every day, and then leave a jar at the acupoints or pain points around the joints. The next day, use moxibustion to smoke the acupoints or pain points of joints, and insist on moxibustion conditioning will receive good results. Moxibustion has a good effect of warming meridians, dredging collaterals, dispelling cold and removing dampness. Don't touch cold things when conditioning, including not blowing cold air.
