Zao Xin Tu is a king ingredient in Huang Tu Tang. Like the name indicates, it means it has more power than other ingredients in the formula.
In Huang Tu Tang, Zao Xin Tu is acrid, warm, and astringent. It warms the Middle Burner, gathers and binds, and stops the bleeding.
In Traditional Chinese Medicine (TCM), Zao Xin Tu belongs to the 'Herbs that stop bleeding' category. Like the name indicates these herbs tend to have hemostatic properties, meaning that they help stop various types of hemorrhages and echymosis. Unlike other herbs they often tend to be used externally.
Furthermore Zao Xin Tu is Warm in nature. This means that Zao Xin Tu tends to help people who have too much 'Cold' in their body, although with less effect than a plant that would be Hot in nature. Balance between Yin and Yang is a key health concept in TCM. Those who have too much Cold in their body are said to either have a Yin Excess (because Yin is Cold in nature) or a Yang Deficiency (Yang is Hot in Nature). Depending on your condition Zao Xin Tu can help restore a harmonious balance between Yin and Yang.
Zao Xin Tu also tastes Sour. The so-called 'Five Phases' theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Sour ingredients like Zao Xin Tu helps with digestion and restrain abnormal discharges of Fluids from the body, such as diarrhea or heavy sweating.
The tastes of ingredients in TCM also determine what Organs and Meridians they target. As such Zao Xin Tu is thought to target the Spleen and the Stomach. In TCM the Spleen assists with digestion, Blood coagulation and Fluids metabolism in the body. The Stomach on the other hand is responsible for receiving and ripening ingested food and fluids. It is also tasked with descending the digested elements downwards to the Small Intestine.
