After the fracture, you can use mugwort to soak feet, but only during the recovery period of the fracture, because mugwort mainly has the function of warming the meridian and dispersing cold, soothing the tendons and opening the ligaments, which can promote blood circulation in the feet during the recovery period of the fracture, promote the swelling and pain in the feet to subside, and also help soften the local joints or soft tissue adhesions, increase the mobility of the joints, and also promote the blood circulation of the fracture and accelerate the healing of the fracture. However, it cannot be applied to the early stage of fracture, because the early stage of fracture mainly appears local bruising, or local swelling is unstable, and applying mugwort to soak feet will dilate blood vessels and lead to more serious local swelling.
