Main benefits

  • Pattern Identification: Traditionally used for the TCM pattern of Lung Qi Deficiency, manifesting as a chronic weak cough, shortness of breath (especially upon exertion), a weak voice, spontaneous sweating, and general fatigue.

  • Core Function: The formula is classically said to tonify Lung Qi, stabilize the exterior, and stop cough and wheezing.

  • Lung and Defensive Qi Relationship: Based on the TCM principle that "the Lungs govern Qi and control the body's exterior," the formula strengthens the internal Lung Qi while simultaneously boosting the Defensive (Wei) Qi to stop abnormal sweating and protect the body from external vulnerabilities.

  • Key Ingredients: Ren Shen (Ginseng) or Dang Shen (Codonopsis) strongly tonifies Qi; Huang Qi (Astragalus) boosts Lung Qi and stabilizes the exterior to stop sweating; Shu Di Huang (Prepared Rehmannia) nourishes the Kidneys to help them grasp and anchor the Lung Qi; Wu Wei Zi (Schisandra) astringes the Lungs and prevents the leakage of Qi; Zi Wan (Aster Root) and Sang Bai Pi (Mulberry Root Bark) gently descend Lung Qi and stop coughing.

  • Emotional Component (TCM): Often indicated when chronic respiratory weakness is accompanied by low spirits, melancholy, or physical exhaustion driven by prolonged grief, reflecting the TCM understanding that "grief and sadness deplete Lung Qi."

  • Region of Action: Primarily acts on the Lungs, respiratory system, and exterior surface (skin and pores), while also gently supporting the Kidneys' ability to anchor the breath.

  • Classical Heritage: Recorded in the Ming-dynasty text Zheng Zhi Zhun Sheng (Standards of Diagnosis and Treatment) by Wang Ken-Tang in 1602, it serves as a foundational prescription for chronic, consumptive Lung conditions.

Weinsch Lung Qi & Vitality Formula Extra Strong is based on the classical Bu Fei Tang (“Tonify the Lungs Decoction”), first recorded in the Ming‑dynasty medical text Zheng Zhi Zhun Sheng (“Standards of Diagnosis and Treatment”) by the physician Wang Ken‑Tang. Within traditional Chinese herbal literature, this specific combination of botanicals - including Huang Qi (Astragalus Root), Ren Shen (Ginseng Root), Wu Wei Zi (Schisandra Fruit), and Sang Bai Pi (Mulberry Root Bark) - was described as a method to “tonify Lung Qi,” “stabilize the exterior,” and “preserve Lung Yin” in accordance with the TCM theoretical framework. These descriptions belong exclusively to the traditional conceptual system of Chinese medicine and do not refer to modern anatomy, psychology, or scientifically validated physiological effects.

Mechanistic Evidence (2025): A recent study investigated the therapeutic mechanism of Bufei Decoction in COPD models. It found that the formula dose-dependently ameliorated COPD-induced lung injury, improved pulmonary function (FEV1, FVC) and blood gas levels, and reduced systemic inflammation. Network pharmacology identified that active components - particularly Schisandrin B from Schisandra - strongly target the TLR4/JAK1/STAT3 signaling pathway to suppress inflammatory cascades.

Immune Regulation: A 2022 study showed that Bufei Decoction improves Lung-Qi deficiency in COPD by balancing the Th17/Treg cell ratio in peripheral blood. It significantly decreased the percentage of pro-inflammatory Th17 cells, effectively dampening chronic systemic inflammation. Other animal studies have noted that BFT reduces the expression of MMP-9, thereby mitigating airway remodeling and structural lung degradation.

Clinical Efficacy: Clinical observations of patients with stable COPD treated with Bu Fei Tang (often integrated with standard care) demonstrated significant improvements in cough, expectoration, and wheezing. In comparative trials, patients receiving BFT showed a higher total effectiveness rate (e.g., 90% vs 75% for standard care alone) and experienced noticeably fewer acute exacerbations over a 3-month follow-up period.

  • In traditional and modern practice, Bu Fei Tang is not typically used during acute asthma attacks but is highly regarded for the remission stage to strengthen the lungs and prevent future attacks.​

  • A clinical study involving 35 patients with bronchial asthma in the remission phase showed that Bu Fei Tang yielded a 94.28% total effectiveness rate, highlighted by significant improvements in pulmonary function tests (FVC%, FEV1).​

  • For chronic bronchitis, a 21-day trial of Bufei granules in 36 patients resulted in significant reductions in chronic cough and sputum volume, alongside marked improvements in lung capacity.
