What are the herbs that specialize in treating the deficiency of middle qi?

There is no such thing as a Chinese medicine that specializes in treating deficiency of middle qi. Chinese medicines that can be used to treat Zhongqi deficiency (weakness of the qi of the spleen and stomach) include proprietary Chinese medicines (e.g., Tonify Zhong Yiqi Pill, Gui Spleen Pill, etc.), Chinese herbal formulas (e.g., Tonify Zhong Yiqi Soup, Sijunzi Soup, etc.), and Chinese herbal medicines (e.g., jujubes, Radix et Rhizoma Ginseng, Radix Astragali, etc.). Insufficiency of middle qi refers to the disease of weak qi in the middle jiao of the spleen and stomach, dysfunction of transportation and transformation, with clinical manifestations such as low voice, shortness of breath and fatigue, low food intake and abdominal distension, and loose stools (thin and unshaped feces). 1. Proprietary Chinese medicines, such as Tonify the Middle Jiao Qi Pill, Ginseng Pill for Strengthening the Spleen, Gui Spleen Pill, etc., can also be used to tonify the middle Jiao Qi. 2. Chinese herbal medicines, such as tonifying the middle Jiao Qi Tang, Gui Spleen Tang, Si Jun Zi Tang, etc., can be used to tonify the middle Jiao Qi. 3. Chinese herbs: mainly including jujube, Radix et Rhizoma Ginseng, Radix Astragali, Radix et Rhizoma Glycyrrhizae. Among them, jujube is sweet and warm, good at tonifying the middle and benefiting qi; Radix et Rhizoma Ginseng is sweet and flat, besides tonifying the middle and benefiting qi, it can also nourish blood; Radix Astragali is sweet and warm, good at tonifying the middle and benefiting qi, and lifting yang to raise the sun (lifting up yang qi of the body to lift up the organs that have been sunk); Radix et Rhizoma Glycyrrhizae is sweet and flat, it can also benefit the qi and tonify the middle. Specific therapeutic drugs should also be based on the patient’s own specific disease manifestations in the physician under the guidance of diagnosis, not blindly self-medication, so as not to cause damage to the body.
