When the physical form is deficient, warm it with Qi; Qi belongs to Yang. This is what Heaven uses to nourish humans. When essence is deficient, tonify it with flavor; flavor belongs to Yin. This is what Earth uses to nourish humans. Humans are born receiving the central energy of Heaven and Earth; Yin and Yang must not be excessively dominant. Excessive dominance leads to deficiency. Thus, methods of tonification and nourishment exist, but they must reach a state of balance and stop; excess leads to surplus, which also deviates from the Mean. The common sentiment is that one knows tonification is beneficial but does not understand that Yin and Yang require equilibrium. Therefore, those discussing tonification focus exclusively on mineral drugs (Jinshi) and moxibustion. What is named "tonification" actually causes dryness; how can this be said to know the way of tonifying deficiency and supporting emaciation? Men often suffer from Kidney deficiency, which is a lack of Water. Generally, tonifying deficiency uses drying herbs, which ignores the fact that the Kidney dislikes dryness. Women often suffer from Yin deficiency, which is a lack of Blood. Generally, tonifying deficiency uses Yang-promoting agents, which ignores the fact that Yang excess leads to further Yin depletion. Moreover, tonifying the upper body should be gradual, while tonifying the lower body should be rapid. For the deficiency and emaciation of the Five Zang organs, tonification must proceed via the generating mother organ (Tonify the Mother when deficient). Regarding the host and guest factors of Yunqi (Five Movements and Six Qi), each tonification corresponds to specific flavors. Those who do not comprehend the principles of Heaven and Earth's Yin-Yang dynamics, and the laws of waxing and waning, will find it difficult to discuss these matters.

The pathogenic factor injuring humans varies in depth. The drug's attack on the pathogen varies in intensity. At the onset of disease, treat the mild stage with Tangye (decoctions). If the disease has persisted for a long time, use Jaoli (fermented wine preparations) to attack the severe stage. Therefore, if the patient's complexion indicates shallow pathogenic involvement, Tangye is the primary treatment; if deep, "Qi" (a potent medicinal preparation or therapy) is required; if extremely deep, Jaoli is the treatment. Additionally, for conditions arising from fright or shock affecting the form, leading to meridian obstruction and numbness (Bu Ren), treat with Jaoyao (wine-based medicine). From this, we see that when pathogens have penetrated deeply and meridians are blocked, without the ability of Jaoyao to disperse pathogens and promote blood circulation, recovery cannot be guaranteed. Thus, Tangye functions to cleanse and wash away pathogens, while Jaoli functions to promote circulation through obstructions. For newly onset diseases, Tangye is mostly used, taking advantage of its cleansing power, which is superior to pills and powders. For chronic, deep-seated diseases, Jaoli is used, employing various methods. Because pathogens are firmly entrenched, recovery may be slow; thus, in prescription usage, wine-based preparations account for six or seven out of ten cases. The general rule is that Jaoli formulas are suitable for the three winter months and should be discontinued after Lichun (Start of Spring). Those using herbal pastes/powders should keep two or three doses of wine medicine during the three winter months regardless of illness, and cease intake after Lichun, thereby preventing myriad diseases. Furthermore, wine has a fierce heat nature and primarily promotes the action of drugs. Therefore, patients with pre-existing Blood deficiency and Qi stagnation, chronic cold and stubborn cold, hemiplegia and paralysis, spasms, bi-syndrome, and convulsions are all suitable for regular consumption, relying on its gradual permeating power. Additionally, ancient methods of administering medicine often used wine, not only to promote Qi and Blood circulation but also to nourish Yang.
