There is no prescription for cold feet, cold feet need to be adjusted and improved according to different causes. The causes of cold feet include lack of yang qi, liver depression and stagnation of qi (poor transportation of qi and blood in the liver, emotional depression), etc. Patients need to use the appropriate medication. 1. Yang qi deficiency: If you do not take proper warming measures or consume cold food for a long time, it will lead to Yang qi deficiency. Medicines such as Diguang Pills with Gui and Jin Gui Kidney Qi Pills can be used to warm the kidneys and support yang (warming and tonifying the yang qi of the kidneys), so as to improve the symptom of coldness (fear of coldness and cold limbs). 2. Liver depression and stagnation of qi: When liver depression and stagnation of qi prevent qi and blood from reaching the feet, it can also cause cold feet. Medicines such as Jia Wei Yi Pill and Si Rei San can be chosen to relieve liver depression (treating depression by unblocking the liver’s qi), thus improving the symptom of cold feet. Patients should go to the hospital promptly after experiencing uncomfortable symptoms, and use medicines under the guidance of physician’s diagnosis.
