What condition is treated with the formula Li Zhong Wan?

Li Zhong Wan, also known as the "Regulate the Middle Pill," is a classical formula primarily used for the treatment of Spleen Yang Deficiency. This condition is characterized by symptoms such as fatigue, a pale tongue, weak pulse, digestive issues, and feelings of coldness due to the insufficient warming function of the Spleen.

The essence of Li Zhong Wan is in its ability to tonify Spleen Yang by warming and strengthening the digestive system. It typically contains ingredients such as ginseng and ginger, which are known to invigorate and warm the Spleen, making it effective for restoring proper function and improving energy levels.

While Spleen Qi Sinking and Spleen Cold-Damp are conditions that can arise from Spleen Yang Deficiency, they describe other aspects of Spleen dysfunction. Spleen Qi Sinking often presents with prolapse or heavy sensations, and Spleen Cold-Damp refers to a situation where dampness accumulates alongside a deficiency of Yang, but the primary focus of Li Zhong Wan is to address the Yang deficiency itself. HT Phlegm Fire pertains to a different organ system issue, relating to the Heart and does not align with the core action of Li Zhong Wan.
