Spleen deficiency is difficult to recover completely. Spleen deficiency can be regulated by taking medicines such as Ginseng Ling Bai Zhu San, Tonifying the Middle Jiao Qi Tang, Pian Zi Li Zhong Wan, Gui Spleen Tang and diet. Medications should be used under the guidance of a doctor. The course of spleen deficiency is usually long, and its formation takes a long time, mainly due to a variety of factors such as dietary factors, mental factors, physiological factors, etc., so it is difficult to recover completely. Spleen deficiency includes Spleen-Qi deficiency, Spleen-Qi deficiency, Spleen-Yang deficiency, and Spleen-Doesn’t-Control-Blood (the Spleen cannot control blood), which are mostly related to diet and diseases. Spleen-Qi deficiency can be treated with Ginseng Ling and Atractylodes Macrocephalae, which strengthens the spleen and strengthens Qi, and stops diarrhea by exuding dampness. Spleen qi deficiency can be treated with tonifying zhong yi qi soup to replenish zhong yi and raise yang and lift the sun (to raise yang qi of the organism to lift the sunken organs). It is contraindicated in cases of yin deficiency with fever and internal heat; in cases of spleen yang deficiency, use Radix Rehmanniae Pill to strengthen the spleen and warm the yang. For pregnant women, caution should be exercised; if the spleen does not regulate blood, use Spleen Booster to benefit qi and replenish blood. Allergy sufferers should be cautious. Although it is difficult to recover completely from spleen deficiency, it can be improved through daily adjustments, taking traditional Chinese medicines or improving lifestyle habits such as eating regularly, regular meals, avoiding overeating, avoiding cold drinks and so on.
