Yin-Yang is the generalization of the two opposite aspects of things or phenomena which are interrelated in the natural worlds. Yin and yang represent not only the two inter-opposite things or forces, but also the two intra-opposite aspects existing within one object [[1],[2]]. The Traditional Chinese Medicine (TCM) holds that the normal body metabolism is based on the balance of Yin and Yang inside the body.

 

The Yang Tonics in TCM are those can replenish and strengthen the body Yang, dispel cold and treat for Yang-deficiency syndrome [[3]].

To restore the balance of Yin and Yang is one of the fundamental laws for replenishing the offset of body metabolisms and treating the disorders in clinics.

Yang tonics are often used in Yang deficiency, such as: aversion to cold and comfort to warm; cold limbs; tastelessness and hydroadipsia; prefer warm food and drink; abdominal cold or pain, or diarrhea when eating cold; cold pain in waist and knees; clear copious urine; loose watery stool; Pale, wet and swollen tongue with white and smooth coating, weak or deep-slow pulse. In clinics, the deficiency is distinguished for Yang deficiency of spleen, Yang deficiency of heart and Yang deficiency of kidney.

Yang deficiency of spleen: cold body and cold extremities; abdominal pain and relieved by pressure and warmth; reduced food intake; sallow complexion; loose, watery stool; pale tongue; deep, thready, slow and weak pulse.

Yang deficiency of heart: chills and cold extremities; stifling oppression; pale or gloomy complexion, palpitation, shortness of breath, fat, tender and pale tongue with dark purple color; thready and weak pulse or knotted and intermittent pulse.

Yang deficiency of kidney: pale complexion; chills and cold extremities; spontaneous perspiration; impotence; infertility; clear and cold leucorrhea;  dizziness, tinnitus, clear copious urine or nocturia; pale tongue with white fur; deep, slow and weak pulse [[4]].

As shown in the table below, Yang tonics usually have tonic functions of kidney, spleen and heart. The most direct pulse basis is slower heart rate, which is the guideline principle to use TCM Yang tonics. This category of drugs is often combined with the use of interior-warming herbs, liver and kidney tonics and spleen and lung tonics. Yang tonics are usually sweet, warm and dry in property. They are easy to progress fire and impair Yin. Therefore, Yang tonics can’t be used for those with Yin deficiency and fire excess [11].

Yin and Yang are rooted in each other. The deficiencies of Yin and Yang can be inter-impairment to each other. Therefore, when Yin or Yang deficiency is treated, we must pay attention to the principles of “Seeking Yin in Yang” or “Seeking Yang in Yin”, which is the combination of Yin tonics while in tonifying Yang; and the combination of Yang tonics while in tonifying Yin [[5]].

In addition, Qi deficiency will follow the Yang deficiency gradually; while Yang deficiency is the extremity of Qi deficiency. Yang and Qi deficiencies always appear together. Therefore, Yang and Qi tonics should be used reasonably to reach the best effects [[6]].
