Common TCM formulas in which dong quai are used*:
In Traditional Chinese Medicine (TCM), dong quai are plants that belong to the 'Tonic herbs for Blood Deficiency' category. Tonic herbs are used for patterns of Deficiency, when one lacks one of the 'Four Treasures' (Qi, Blood, Yin and Yang). Blood tonics tend to be bitter-sweet with either a Warm or neutral nature. Because the Liver stores Blood, all Blood tonics enter that Organ meridian.
As suggested by its category dong quai are plants that are Warm in nature. This means that dong quai tend 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 dong quai can help restore a harmonious balance between Yin and Yang.
Dong quai also taste Pungent and Sweet. The so-called "five elements" theory in Chinese Medicine states that the taste of TCM ingredients is a key determinant of their action in the body. Pungent ingredients like dong quai tend to promote the circulations of Qi and body fluids. That's why for instance someone tends to sweat a lot when they eat spicy/pungent food. On the other hand Sweet ingredients tend to slow down acute reactions and detoxify the body. They also have a tonic effect because they replenish Qi and Blood.
The tastes of ingredients in TCM also determine what organs and meridians they target. As such dong quai are thought to target the Spleen, the Heart and the Liver. In TCM the Spleen assists with digestion, blood coagulation and fluid metabolism in the body. In addition to regulating blood flow, the Heart is believed to be the store of the "spirit" which basically refers to someone's vitality. The Liver is often referred as the body's "general" because it is in charge of regulating the movements of Qi and body fluids. It also takes a leading role in balancing our emotions.
