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. Si Sheng Wan is designed to correct these specific patterns.
Why Si Sheng Wan addresses this pattern
Blood-Heat recklessly moving (血热妄行) is the core pattern this formula addresses. When Heat enters the Blood level, it damages vessel walls and drives blood out of its normal pathways, causing bleeding that is bright red, sudden, and often from the upper body. The formula's entire composition targets this pattern: Ce Bai Ye and Sheng Di Huang powerfully cool the Blood and stop bleeding, He Ye clears Heat while dispersing stasis, and Ai Ye reinforces hemostasis while preventing the cold herbs from causing new stasis. The emphasis on fresh, unprocessed herbs maximizes cooling potency. This formula is specifically designed for acute, excess-type Blood-Heat bleeding rather than chronic deficiency bleeding.
A practitioner would look for one or more of these signs
Bright red blood, sudden onset
Blood is fresh red, forcefully expelled
Bright red blood in sputum or pure blood
Dry mouth and throat from Heat consuming fluids
Tongue red or deep red (绛), indicating Blood-level Heat
Commonly Prescribed For
These conditions can arise from the patterns above. A practitioner would consider Si Sheng Wan when these conditions are specifically caused by those patterns — not for all cases of these conditions.
TCM Interpretation
In TCM, recurrent or heavy nosebleeds are most commonly attributed to Heat affecting the Lung and Stomach channels, which pass through the nasal region. When the Liver stores excessive Heat (Liver Fire), it can "punish" the Lung (since Wood controls Metal in five-phase theory), driving hot blood upward to the nose. The blood is characteristically bright red, the flow can be profuse, and it is typically accompanied by signs of internal Heat such as a dry throat, irritability, and a red tongue.
Why Si Sheng Wan Helps
Si Sheng Wan directly targets the Blood-Heat mechanism underlying nosebleeds. Ce Bai Ye (Biota leaves) enters the Lung channel and is one of the most effective herbs for cooling the Blood in the nasal vessels. Sheng Di Huang cools Blood at a deeper level and replenishes the Yin fluids consumed by the Heat. He Ye clears ascending Heat in the Stomach channel (which passes alongside the nose), while Ai Ye strengthens the overall hemostatic effect. Clinical studies have shown effectiveness rates above 93% for nosebleeds treated with this formula as the base prescription.
TCM Interpretation
Coughing up blood (hemoptysis) is understood in TCM as resulting from Heat or Fire damaging the blood vessels in the Lung. A common mechanism is Liver Fire "punishing" the Lung, where excessive Heat from the Liver rises and attacks the delicate Lung tissue. The Lung is considered a "tender organ" (娇脏) that is easily injured by Heat. When Heat scorches the Lung's vessels, blood leaks into the airways and is coughed up. Bright red blood with a dry cough, dry throat, and red tongue point clearly to a Blood-Heat pattern.
Why Si Sheng Wan Helps
The formula's composition is well suited to hemoptysis from Blood-Heat. Ce Bai Ye enters both the Lung and Liver channels, cooling Blood in the Lung while also addressing Liver Fire at its source. Sheng Di Huang clears Heat from the Blood level broadly and protects Yin fluids, which is important since the Lung needs moisture to function. He Ye and Ai Ye round out the hemostatic action. This formula is commonly used in cases of pulmonary tuberculosis and bronchiectasis where hemoptysis fits the Blood-Heat pattern.
Also commonly used for
Hematemesis from gastric ulcers or other causes when due to Blood-Heat

How It Addresses the Root Cause
TCM doesn't just suppress symptoms — it aims to resolve the underlying imbalance. Here's how Si Sheng Wan works at the root level.
This formula addresses bleeding caused by Heat in the Blood level forcing blood out of the vessels, a condition known in TCM as "Blood-Heat recklessly moving" (血热妄行). When excessive Heat accumulates in the Blood, it damages the vessel walls and drives blood outward and upward, leading to bleeding from the upper body, particularly the nose, mouth, and lungs.
The Liver stores Blood and belongs to Wood. When Liver Fire flares, it can "punish" the Lung (Metal), since Wood controls Metal in the five-phase cycle. This causes coughing or spitting of blood. Liver Fire can also rebel against the Stomach, forcing blood upward as vomiting of blood. The Heat also consumes Yin fluids, producing dryness of the mouth and throat, a red or deep red tongue, and a wiry, rapid pulse. The bleeding is characteristically bright red because the Heat is vigorous and the blood is being forcefully expelled.
Because the root cause is Heat in the Blood driving blood recklessly out of its proper channels, the treatment principle is to cool the Blood and stop the bleeding. However, an important concern is that overly cold and astringent approaches can congeal blood and create stasis. This formula addresses that risk through its careful composition.
