Clinical Experience of Treating Metabolic Associated Fatty Liver Disease with Huangqi （Radix Astragali） in Lingnan （岭南） Area / 中医杂志

ABSTRACT

Based on the unique syndrome characteristics of metabolic associated fatty liver disease （MAFLD） in Lingnan （岭南） area， this paper discussed the clinical experience of Huangqi （Radix Astragali） in the treatment of MAFLD in Lingnan area. It is summarized that spleen deficiency and yang weakness， and internal accumulation of damp-turbidity are the source of the disease， and at the early stage， Huangqi， commonly 15~30 g， could be used to fortify the spleen and warm the earth， thereby making the deficiency fire latent， as well as raise the clear and warm the exterior so as to inhibit damp-turbidity； medication needs to be progressively supplemented， and can be used together with Taizishen （Radix Pseudostellariae）， Baizhu （Rhizoma Atractylodis Macrocephalae）， Fuling （Poria）， and Fangfeng （Radix Saposhnikoviae） to back up the earth and inhibit dampness. Qi stagnation and blood constraint， yin dampness and heat accumulation are the pathogenesis of disease progression. Huangqi should be taken to invigorate the spleen and flourish the liver， unblock yang， and move stagnation. The dosage is often maintained at 30~60 g， to circulate the qi and unblock yang qi in the middle jiao （焦）， usually combined with Chaihu （Radix Bupleuri）， Baishao （Radix Paeoniae Alba） and Yujin （Radix Curcumae） integrating warm and cool medicinals. Stubborn turbid and fat condensing in the liver is a severe stage of the disease and may be concurrent with various pathogens such as dampness， phlegm， and heat， for which 60~90 g Huangqi should be used to invigorate blood and disperse fat， reinforce healthy qi and expel pathogens， often with medicinals that can disperse fat and direct the turbid downward such as Shanzha （Fructus Crataegi）， Juemingzi （Semen Cassiae）， Lulutong （Fructus Liquidambaris） and Zexie （Rhizoma Alismatis）. When prescribing， it is suggested to combine with other medicinals according to the season， thereby adjusting the ascending and descending of the property of Huangqi， thereby conforming to the nature of the four seasons.
