The principles and methods of treating blood deficiency in TCM mainly include invigorating spleen and regulating stomach, benefiting qi and generating blood, tonifying kidney and generating blood, removing blood stasis and generating blood, and detoxifying and generating blood. In this respect, Defu's snowflake tea is a good way to recuperate and improve the symptoms of deficiency of both qi and blood.
(1) Strengthening spleen and regulating stomach
Spleen and stomach are the source of blood biochemistry. If the diet is moderate, the function of spleen and stomach transport and transformation is normal, and hematopoiesis will naturally continue. Therefore, we must first strengthen the spleen and stomach and replenish blood. If the spleen and stomach are strong, the source of biochemistry will be endless. Commonly used prescriptions include Sijunzi Decoction, Siwu Decoction and Danggui Buxue Decoction.
(2) supplementing qi and generating blood
The material basis of blood is essence, and essence entering blood is driven by qi. In the Qing Dynasty, Li Zhongzi's "Required Reading for Doctors" said: "Qi and blood are important, and qi is before blood; Both yin and yang are needed, and nourishing yang is above nourishing yin. " Treatise on Febrile Diseases said: "Those who are good at blood do not seek tangible blood, but seek intangible qi." "Jing Yue Quan Shu" said: "Tangible blood is hard to grow quickly, while intangible qi should be solidified urgently." In clinical medication, according to "qi can produce blood", it is often used as a blood-enriching drug, and is accompanied by qi-invigorating products. Commonly used prescriptions include Guipi Decoction and Danggui Buxue Decoction. Commonly used tonics include Radix Astragali, Radix Ginseng, Radix Codonopsis, Atractylodis Rhizoma, Rhizoma Polygonati, Rhizoma Dioscoreae, and Fructus Jujubae. With blood-nourishing drugs, such as Angelica sinensis, Radix Paeoniae Alba, Colla Corii Asini, Radix Rehmanniae Preparata, etc.
(3) tonifying kidney and generating blood
Kidney is the foundation of congenital, storing essence. Essence includes congenital essence and acquired essence. Essence can produce marrow, and marrow can transform blood. At the same time, the vital gate in the kidney is the source of vitality, the root of the twelve meridians, the source of biochemistry, and the motive force of warming the heart and promoting blood circulation. Therefore, Chinese medicine has the saying that "blood is born in the kidney". In clinical treatment of blood deficiency, it is necessary to tonify kidney and replenish essence, and the essence is sufficient and the blood is flourishing. Commonly used prescriptions are Cuscuta Decoction and Erxiandan. Commonly used drugs for tonifying kidney include cornu Cervi Pantotrichum, colla cornus Cervi, colla Corii Asini, Colla Plastri Testudinis, Radix Morindae Officinalis, Herba Cynomorii, Herba Epimedii, Fructus Psoraleae, Semen Cuscutae, Radix Aconiti Lateralis Preparata, Cortex Cinnamomi, Polygoni Multiflori Radix, Radix Rehmanniae Preparata, Fructus Lycii and Placenta Hominis.
