Fu Zi Li Zhong Wan (Fu Zi Li Zhong Pian, Fu Zi Li Zhong Tang), literally "Aconite Regulate Middle Pills" in Chinese, is a classic Chinese herbal medicine for warming the middle energizer and strengthening the Spleen. Today, the Chinese medicine is best used to warm up the cold hands and feet associated with digestive discomforts such as cold stomach, abdominal pain or fullness, diarrhea.

Functions:
In traditional Chinese medicine (TCM), the Spleen is the most important organ of the body in absorbing the nutrients from the food we take and transforming them into the Yin, Yang, and Qi energy etc, the fundamental elements in regulating our overall body functions. A strong Spleen can supply the body abundant Yin, Yang, and Qi energy that may be present at low levels after birth. When the Spleen function is weak, digestion is compromised. Our body may display digestive problems and be in poor health.
A usual problem of Spleen functions is the insufficiency of its Yang energy. Spleen Yang deficiency often comes with the Yang deficiency of the Stomach as well. As a result, one may experience coldness in the stomach, abdominal pain, abdominal distension, diarrhea, vomiting, and coldness of the limbs. For example, one can not take cold milk or ice water, otherwise diarrhea may occur; The abdominal pain can be alleviated after the abdomen is pressed with hands or covered with a warm water bag.
Fu Zi Li Zhong Tang is the primary Chinese herbal medicine that reinforces the Spleen and Stomach Yang energy. The Chinese medicine is composed of several Chinese herbs that strengthen the Yang energy and the Spleen. Among them, Processed Aconite root is perhaps the best known Chinese herb for restoring the Yang energy and dispersing cold; Ginger is acrid and warm in nature and disperses cold; Codonopsis replenishes the Qi energy and harmonizes the Spleen; Atractylodes is a key tonic for the Spleen and Stomach and removes Dampness; Licorice tonifies Spleen and Qi and synchronizes the action of the other herbs.
Fu Zi Li Zhong Wan is indicated in China Pharmacopoeia¹ for warming the middle-Jiao and strengthening the Spleen. The Chinese herb is used for the insufficiency and coldness of the Spleen and Stomach, abdominal pain and coldness, vomiting and diarrhea, cold hands and feet. 
In recent years, Fu Zi Li Zhong Wan has been studied for its application to digestive disorders such as gastritis, enteritis, and gastric ulcers that are diagnosed with modern technologies and at the mean time display the described TCM patterns with satisfactory results. For example, in one study, Fu Zi Li Zhong Tang was used as the basic TCM formula to treat 28 patients with a history of gastric ulcer or peptic ulcer between 3 months to 20 years. After 1 month of treatment, 24 out of 28 were clinically recovered.² In the study, Astragalus, a common Qi tonic Chinese herb, and Angelica, a known Blood tonic herb, were included to the classic Fu Zi Li Zhong Tang herbal formula.
