Can Bu Zhong Yi Qi Wan treat spleen and lung qi deficiency?

Bu Zhong Yi Qi Wan is generally not effective for treating spleen-lung qi deficiency. Bu Zhong Yi Qi Wan is a relatively common traditional Chinese patent medicine that functions to regulate the spleen and kidney and tonify qi and strengthen yang, thereby aiding in the treatment of spleen-stomach deficiency. However, spleen-lung qi deficiency primarily results from insufficient lung qi, whereas Bu Zhong Yi Qi Wan mainly targets the spleen and stomach. Therefore, patients should avoid using this medication indiscriminately, as doing so may not only fail to improve their condition but could also potentially worsen it.
