A Proven, Research-Backed Formula for Hard & Dry Stools
Modern research on traditional herbs commonly used to support digestive health and bowel regularity, particularly Prepared Rehmannia (Shu Di Huang), Angelica Root (Dang Gui), Black Sesame Seeds (Hei Zhi Ma), and Immature Bitter Orange (Zhi Shi), has explored their roles in supporting healthy intestinal function, gastrointestinal motility, hydration of the intestinal tract, and normal bowel movements. Studies have also investigated Codonopsis Root (Dang Shen) and Ophiopogon Tuber (Mai Men Dong) for their traditional use in supporting digestive function, nourishing body fluids, and maintaining gastrointestinal balance.
Research published in the Journal of Ethnopharmacology has examined the traditional pharmacological activities of Angelica Root and its effects on gastrointestinal function and healthy circulation. Additional studies published in Frontiers in Pharmacology have investigated the biological activities of Prepared Rehmannia and its role in maintaining healthy physiological function. Reviews published in Chinese Medicine have also explored the traditional applications of Black Sesame Seeds, Codonopsis Root, and other classical Chinese herbs used to support digestive wellness and bowel regularity.
From a Traditional Chinese Medicine perspective, hard and dry stools are often associated with Intestinal Dryness, Blood Deficiency, Yin Deficiency, or inadequate fluid nourishment of the Large Intestine. Traditional Chinese herbal formulas are designed to nourish Blood and Yin, moisten the intestines, promote the healthy movement of Qi, and support comfortable, regular bowel movements while restoring digestive balance.
