2. Traditional Chinese medicine cloud fire activating kidney therapy

A remarkable feature of the method of tonifying kidney by cloud fire in traditional Chinese medicine is the external application of traditional Chinese medicine.

Traditional Chinese medicine believes that meridians operate the whole body's qi and blood, connect viscera, communicate up and down inside and outside, and regulate the balance of body fluid. The viscera of the whole body are coordinated through meridians, so that the five internal organs, limbs, five senses and nine orifices, and flesh meridians are connected into an organic whole. The therapy of tonifying kidney by cloud fire in traditional Chinese medicine is based on medicinal moxibustion, guidance and massage. External application of traditional Chinese medicine is a therapeutic method to treat renal diseases by directly acting on Shenshu and other acupoints of patients with purified drugs. Li Zhuo's theory of parallel prose is that "the theory of external treatment is the theory of internal treatment, and the medicine of external treatment, that is, the medicine of internal treatment, can make up for each other's shortcomings". Because of the different routes of administration, the drug directly acts on Shenshu and other acupoints, and is conducted through meridians, thus promoting blood circulation, removing blood stasis, nourishing yin and clearing heat.
