Patterns Addressed
In TCM, symptoms don't appear randomly — they cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Tong You Tang is designed to correct these specific patterns.
Why Tong You Tang addresses this pattern
When Blood stasis develops in the Stomach and pyloric region, it obstructs the normal downward passage of food and waste. This formula directly addresses this stasis with Tao Ren and Hong Hua to invigorate Blood and break through the obstruction, while Dang Gui Shen nourishes the Blood so it flows freely again. Sheng Ma restores the ascending-descending dynamic of the Stomach Qi, and the two forms of Rehmannia (Sheng Di and Shu Di) replenish the dried-out Yin and Blood that allowed the stasis to form in the first place.
A practitioner would look for one or more of these signs
Difficulty swallowing, food feels stuck
Dry, hard stools that are difficult to pass
Food eaten is regurgitated back up
Bloating and fullness in the upper abdomen
Why Tong You Tang addresses this pattern
When the Stomach's Yin fluids are depleted by Heat, overwork, or consumption of overly spicy and rich foods, the gastrointestinal tract dries out. The pyloric gate loses its lubrication and fails to open properly. This formula replenishes Stomach Yin with Sheng Di Huang and Shu Di Huang, while Dang Gui Shen nourishes the Blood component of Yin. The moistening and lubricating actions of Tao Ren help restore the intestinal passage, while Sheng Ma lifts the clear fluids back into circulation.
A practitioner would look for one or more of these signs
Dry constipation with hard, pellet-like stools
Dry mouth and throat
Sensation of obstruction in the esophagus or stomach
Commonly Prescribed For
These conditions can arise from the patterns above. A practitioner would consider Tong You Tang when these conditions are specifically caused by those patterns — not for all cases of these conditions.
TCM Interpretation
Chronic constipation in TCM is not always a simple matter of insufficient fiber or water. When the Stomach and intestines have been damaged by Heat (from rich foods, stress, or overwork), the Blood and fluids that normally lubricate the intestinal walls become depleted. Over time, this dryness can give rise to Blood stasis, which further blocks the passage. The result is not just dry stools but a fundamental loss of the gastrointestinal tract's ability to move things downward. The Kidneys, which govern the lower openings of the body including the anus, also play a role: when Kidney Yin is insufficient, the large intestine lacks the moisture it needs.
Why Tong You Tang Helps
Tong You Tang targets constipation that arises specifically from Blood dryness and stasis rather than from Qi deficiency or excess Heat alone. Dang Gui Shen and the two Rehmannia herbs (Sheng Di and Shu Di) replenish the Blood and fluids that have been consumed, restoring moisture to the intestinal walls. Tao Ren and Hong Hua break through the stasis and Tao Ren's oily nature directly lubricates the bowels. Sheng Ma restores the normal descending action of Stomach Qi, which is essential for peristalsis. This makes the formula particularly suited for elderly or chronically ill patients whose constipation stems from dryness and poor circulation rather than acute Heat.
TCM Interpretation
TCM views chronic atrophic gastritis as a condition where the Stomach's nourishing fluids (Yin) have been gradually depleted, often by long-standing Heat, irregular eating habits, or chronic emotional stress. The gastric lining thins and loses its ability to function, which corresponds to the TCM concept of the Stomach losing its moistening and descending capacity. As the tissue becomes malnourished, Blood stasis develops locally, creating a vicious cycle of poor nourishment and stagnation.
Why Tong You Tang Helps
The formula's combination of Yin-nourishing herbs (Sheng Di Huang, Shu Di Huang) and Blood-activating herbs (Tao Ren, Hong Hua, Dang Gui Shen) directly addresses both the atrophy (Yin deficiency) and the local stagnation (Blood stasis). Sheng Ma guides the formula to the Yangming system (Stomach and Large Intestine) and restores proper Qi dynamics. Clinical studies have reported that Tong You Tang achieved over 91% effectiveness in treating chronic atrophic gastritis over a six-month treatment course.
TCM Interpretation
Difficulty swallowing (known in classical texts as 噎膈, ye ge) is understood as a blockage of the passage between the upper and lower digestive tract. Li Dongyuan described this as the 'pyloric gate' (幽门) being obstructed, causing turbid Qi to rush upward and block the 'inhalation gate' (吸门, the epiglottis region). The root cause is typically dryness and Blood stasis that has solidified in the passageway, preventing both the downward movement of food and the normal descent of Qi.
Why Tong You Tang Helps
The formula was specifically designed by Li Dongyuan for this exact condition. Its name literally means 'Unblock the Pylorus.' Dang Gui Shen moistens and nourishes the dried-out tissue, Tao Ren and Hong Hua break through the stasis obstructing the passage, and Sheng Ma restores the ascending-descending balance so that Qi flows downward again and the passage reopens. The two Rehmannia herbs ensure that the underlying dryness is corrected so the condition does not simply recur.

How It Addresses the Root Cause
TCM doesn't just suppress symptoms — it aims to resolve the underlying imbalance. Here's how Tong You Tang works at the root level.
This formula addresses a pattern where Heat damages the Stomach and Intestines, drying out the fluids and Blood that normally keep the digestive tract moist and functioning smoothly. In TCM, the "pylorus" (幽门, you men) is the gateway between the Stomach and the intestines, and the "cardia" (吸门, xi men) is the upper opening of the Stomach. When these passages lose their normal lubrication, the entire middle section of the digestive tract seizes up.
The key pathological sequence works like this: Heat enters the Spleen and Stomach, scorching the Yin fluids and Blood. As Blood dries up, it also stagnates, because fluid movement is what keeps Blood flowing. This creates a vicious cycle: Dryness leads to Blood Stasis, and Blood Stasis further blocks the passageways. The pylorus closes, and food cannot descend properly, causing choking and difficulty swallowing from above. Below, the intestines become parched and the bowels cannot move, leading to stubborn constipation. Qi itself becomes stuck, unable to ascend or descend through these blocked gates.
Li Dongyuan's insight was that this is not simply a case of "too much Heat" requiring harsh purgation. Rather, it is a condition of depleted fluids with concurrent Blood Stasis, where the body has lost its natural internal lubrication. The treatment must therefore moisten what is dry, move what is stuck, and restore the normal upward-and-downward flow of Qi through the digestive tract.
