Spring is the time when everything revives and grows, “Suwen Si Qi Tuning Shen Da Lun”, “Spring is the month of March, this is hair Chen, heaven and earth are all born, everything to glory” Spring should be in the liver, liver qi regulation for the smooth, “spring should nourish the liver”. Dr. Sun Boyang pays attention to nourishing the liver and protecting the liver in his spring treatment, which is briefly summarized and analyzed in two cases. Case 1 Ma Moumou, female, 34 years old, first seen on February 25, 2009 The patient has cold hands and feet, postpartum dizziness, sometimes light and sometimes heavy, low menstrual flow with blood clots, and recently dry vomiting. Lack of energy, bowel regulation, light red and darker tongue, and thin and stringent pulse. The diagnosis is liver stagnation and blood stasis, spleen and stomach disharmony. The treatment is to relax the liver and invigorate blood, strengthen the spleen and harmonize the stomach. Radix Angelicae Sinensis 10g, Radix Paeoniae Alba 10g, Radix Bupleurum Chinense 8g, Atractylodes Macrocephala 10g, Rhizoma Ligustici Chuanxiong 8g, Tribulus terrestris 15g, Neem 9g, Ulmoides 12g, Poria 15g, Plantago 10g, Chuanjian 15g, Motherwort 15g, Peach kernel 10g, Safflower 6g. Case 2 Wu Moumou Female 38 years old first consulted on March 4, 2009 The patient has been troubled by the five hearts for many years, does not drink to quench thirst, poor night sleep, prefers to sleep sitting, red and painful throat, red tongue, slightly yellow coating, sunken pulse, evidence of liver and kidney yin deficiency, treatment to nourish the liver and kidney yin.

Case 1 patient’s liver qi is out of control, liver qi is stagnant, which leads to blood stasis, and the liver thrives in spring, liver wood is in conflict with spleen earth, resulting in disharmony of the spleen and stomach, so the treatment is to regulate the qi of the liver, so that the liver qi can be relaxed, and at the same time activate blood circulation, remove blood stasis, strengthen the spleen and stomach, in order to achieve peace between liver wood and spleen earth. At the same time, Angelica sinensis and Paeonia lactiflora were used to protect liver yin to avoid depletion of liver yin by warming and regulating qi. In case 2, the patient’s liver and kidney yin deficiency has been prolonged, and yin does not control yang, so the treatment should nourish yin, nourish liver and kidney, and protect yin fluid. It is important to nourish the liver in spring, and the liver and kidneys are of the same origin, so nourishing kidney water helps to nourish liver yin, and together they can achieve the effect of nourishing the liver and kidneys. In Su Wen Yin Yang Ying Xiang Da Lun, “The east produces wind, wind produces wood, wood produces acid, acid produces liver, liver produces tendons, tendons produce heart. In the sky is the mystery, in the people of the Tao, in the earth is the transformation. In the sky is the wind, in the earth is the Tao, in the earth is the transformation. God is wind in the sky, wood in the earth, tendons in the body, softness in the qi, and liver in the hide. Its nature is pleasant, its virtue is and, its use is moving, its color is pale, its transformation is Rong …… its order to declare the hair, its change to destroy, its cataract is meteoric, its taste is acid, its will is anger. Anger hurts the liver, sadness is better than anger; wind hurts the liver, dryness is better than wind; acid hurts the tendons, pungency is better than acid.” Spring liver should pay attention to nourishing liver yin, regulate the liver qi, at the same time “know that the liver disease when the first transmission of spleen”, so you need to cultivate the earth to strengthen the spleen to prevent the transmission of change; spring should also abstain from anger, otherwise depletion of liver wood, due to the emotions cause disease; spring eating acid not too much to prevent damage to liver qi. The patient’s pulse should be sine to be smooth, and the medicine should be sour and sweet to nourish liver yin and sour and pungent to help liver yang.
