Mugwort soaking legs to treat thrombosis of lower limbs is actually a very unscientific practice. Lower limb thrombosis according to its pathology can be divided into lower limb arterial thrombosis and venous thrombosis, no matter which thrombosis, are due to the existence of blood clots in the blood vessels, resulting in blood return obstruction, causing the symptoms of lower limb stasis or ischemia. Mugwort is an herb with antiseptic and anti-inflammatory effects, but it does not have any effect of activating blood circulation and promoting microcirculation. Therefore, mugwort soaking legs to treat blood clots will not fundamentally solve the embolism of blood clots, nor will it promote the generation of new blood vessels to improve the symptoms of blood clots. On the contrary, because mugwort soaking legs can irritate the skin and lead to ulcers, forming venous and arterial ulcers, which will not heal over time and will aggravate the symptoms of thrombosis. Therefore, it is not clinically recommended to use mugwort to treat thrombosis, and once thrombosis is formed, it is necessary to go to vascular surgery for professional consultation and treatment.
