There is no such thing as a proprietary Chinese medicine to “open up” the blood vessels. To open up the meridians in the legs, it is necessary to identify the symptoms and use medicines, and choose the appropriate Chinese medicines or proprietary Chinese medicines according to the different types of certificates, for example, cold-damp paralysis obstruction, rheumatism-heat paralysis (often manifested as burning joints and muscles, pain, redness, swelling, etc.), and blood stasis due to deficiency of qi. 1. Cold-dampness paralysis: If the lower legs feel wind-cold, or are often soaked in cold water, it will cause cold-dampness paralysis and blockage of meridians, resulting in leg pain, which is aggravated by cold and relieved by heat, and the lower limbs are cold. Generally speaking, we can use medicines that can dispel cold and remove dampness, and alleviate paralysis and relieve pain (relieve pain by unblocking the paralysis of the limbs) such as Cold-dampness Paralysis Capsules, DuoYu Parasitic Soup and XiaolongLuoPan. 2. Rheumatism-heat paralysis (often manifested as burning, pain, redness and swelling of joints and muscles, etc.): generally caused by wind and dampness blocking the meridians and channels, and then accumulated and transformed into heat, manifested as redness, swelling and pain in joints of limbs and skin temperature, aggravated by heat and alleviated by cold, can be used to eliminate wind and dampness (eliminating wind and dampness in the body), and to remove heat to alleviate pain of the medicines, for example, dampness-heat paralysis punch, four-miao pills and so on. 3. Qi deficiency and blood stasis: If the body is deficient in qi, then qi deficiency will push the blood to run, thus causing blockage of meridians and collaterals to cause acidity and pain and other discomforts, these patients often have shortness of breath and laziness, fatigue and other manifestations, and they can use qi and blood circulation (replenish qi and blood to make the body full of qi and blood and blood circulation) to promote the use of medicines, such as Taohong Sizi Soup, Blood stasis and blood paralysis capsule, Qiribi capsules, and so on. It is suggested that patients should not use drugs blindly, and should go to a regular Chinese medicine hospital to find a doctor to identify the evidence for treatment.
