The herbs of choice for inducing fire to return to the source (inhibiting the rise of fire-evil in the kidneys) are usually cinnamon, epimedium, and hippocampus. Lead Fire to Yuan (inhibit the rise of fire in the kidneys) is a Chinese medicine term that is mainly used for treating the conditions of yin-sheng and yang, where the yin is more powerful and the deficient yang is more powerful than the yang. The so-called yin-sheng and yang-floating, mainly refers to the body’s strong yin qi and weak yang qi, resulting in the weak yang qi floating over the body’s upper jiao, while the middle and lower jiao are full of yin and cold. It can be manifested as irritability, insomnia, red face and ears, mouth ulcers, sore throat; cold pain and weakness in the waist and knees, cold feet, cold legs and other symptoms. The so-called “Drawing Fire Back to the Source” (inhibiting the rising of fire evil in the kidneys) is able to dispel yin and cold in the lower jiao and enhance the yang force, so that the yang that floats over the upper jiao, returns to the lower jiao. Such medicines mainly include Chinese herbs that have the effect of warming and tonifying kidney yang (warming and replenishing the yang energy of the kidneys), such as cinnamon, epimedium, and hippocampus. In order to enhance the efficacy and alleviate the symptomatic manifestation of excessive fire-heat in the upper Jiao, it can be used in conjunction with Huang Lian (黄黄连) which clears fire-heat in the upper Jiao. Of course, if you are not feeling well, it is still recommended that you seek medical attention and follow the doctor’s instructions, rather than taking medication without authorization.
