It is indicated for fatigue, generalized weakness, and visceral prolapse. The pills are dark brownish-black in color and possess a slightly sweet and pungent taste. So, what are the therapeutic effects of Buzhong Yiqi Wan, and who is it suitable for? Below, we address these questions.

Therapeutic Effects of Buzhong Yiqi Wan

1. Treatment of Spleen-Stomach Deficiency and Sinking of Central Qi

This formula tonifies the Spleen and Stomach, augments Qi, and lifts sinking Qi. Spleen-Qi deficiency refers to a syndrome characterized by insufficient Spleen-Qi and impaired transportation and transformation functions. It commonly arises from irregular diet, excessive physical or mental strain, or prolonged illness depleting Spleen-Qi. Buzhong Yiqi Wan is indicated for diarrhea, rectal prolapse, and other conditions resulting from Spleen-Stomach deficiency and sinking of Central Qi, manifesting as fatigue, poor appetite, abdominal distension, loose stools or chronic diarrhea, and a sensation of rectal heaviness or prolapse. Ingredients such as Bupleurum (Chai Hu) and Angelica (Dang Gui) in this formula help tonify Qi and nourish Blood.

2. Regulation of Qi-Deficiency Fever

Qi-deficiency fever is a specific type of internal injury fever, presenting with low-grade, persistent fever, aversion to wind, spontaneous sweating, lassitude, shortness of breath, susceptibility to external pathogenic factors, pale complexion, pale tongue, white coating on the tongue, and a fine, rapid, and weak pulse. Buzhong Yiqi Wan is generally suitable for individuals with Qi and Blood deficiency. If symptoms such as cold limbs, dizziness, and fatigue occur, it may be used under the guidance of a physician. Women with Qi and Blood deficiency may also use this formula to regulate their constitution.

Appropriate Populations for Buzhong Yiqi Wan

1. Buzhong Yiqi Wan is suitable for individuals with Qi and Blood deficiency, including women with Qi and Blood deficiency. During treatment, avoid hard-to-digest foods; individuals with known allergies should not take this formula. Discontinue use immediately if headache, dizziness, or other adverse reactions occur.

2. Buzhong Yiqi Wan is appropriate for individuals with Spleen-Stomach deficiency, sinking of Central Qi, and Qi and Blood deficiency. However, it is contraindicated for those with Yin-deficiency fever or exogenous febrile diseases (e.g., common cold with fever). Additionally, children, pregnant or lactating women, and patients with severe chronic conditions—including hypertension, heart disease, liver disease, diabetes, or kidney disease—should use this formula only under the supervision of a qualified physician.

The above outlines the therapeutic effects and appropriate populations for Buzhong Yiqi Wan. Generally, this formula may be taken either before or after meals; however, since it is a tonic preparation, optimal efficacy is achieved when taken on an empty stomach (i.e., before meals).
