There is no prescription for cold lower body. Coldness in the lower half of the body is often caused by kidney yang deficiency, and can be relieved by mashing and pasting Wu Zhu Zhu on the Yong Quan acupoints to achieve the effect of inducing fire to return to the source (inhibiting the rising of fire evil from the kidneys). Cornus officinalis is a hard, hot Chinese herb with the effects of dispersing cold and relieving pain (relieving pain by removing cold from the body), lowering the rebelliousness and stopping vomiting (stopping the upward flow of stomach qi and stopping vomiting), and assisting yang in stopping diarrhea. It also has the effects of tonifying the kidney and warming the liver, warming the meridians and opening the channels. It enters the liver meridian, and the liver and kidney have the same origin. Applied to the Yongquan acupoint, it can warm the lower body through the kidney meridian by inducing heat downward. The amount should not be large when used externally, and it is applied at night, removed during the day, and applied to both feet. If there is no adverse reaction, you can insist on applying the paste for a period of time before it becomes effective. The application of Chinese medicine requires evidence-based treatment, please seek an interview with a Chinese medicine practitioner for evidence-based guidance on the use of medication.
