What is the effect of soaking leek roots in white wine?

Apply leek and wine to the knee joint. Leek with liquor has the effects of promoting blood circulation, removing blood stasis and dredging collaterals. The specific method is as follows: wash a proper amount of leek, chop it until the water evaporates, then mix it with a small amount of wine with a temperature above 60 degrees and mix well. Finally, wrap the leek in gauze and apply it to the swollen joint, fix it with medical tape, and take it off after the body is hot and sweaty.
