The diseases treated by Tongqiao Huoxue Decoction are listed below.
Hair loss after Shanghan (Cold Damage) or Wenyi (Plague/Epidemic diseases): Famous physicians' books all state that this is due to blood injury, but they do not realize that blood stasis in the subcutaneous tissue and outside the skin blocks the blood vessels, preventing new blood from nourishing the hair, thus causing hair loss. Hair loss without illness is also due to blood stasis. After taking three doses of this medicine, hair loss will stop; after ten doses, new hair will certainly grow.
Eye pain with redness of the sclera, commonly known as "Bao Fa Huo Yan" (Sudden Fire Eye). The blood is scorched by fire-heat and coagulates in the eyeball, causing the sclera to turn red. Regardless of whether there is a nebula (corneal opacity) or not, first take one dose of this medicine, then take Jiawei Zhitong Moyao San (Modified Pain-Relieving Myrrh Powder), two doses per day, and recovery will surely occur within two or three days.
Redness indicates blood stasis. Regardless of whether the condition has lasted for thirty or twenty years, this formula will show effects after three doses and can achieve a cure after twenty to thirty doses. Apart from this, there are no other verified prescriptions.
The small tube inside the ear hole connects to the brain. If blood stasis presses against the outside of the tube, closing it, deafness results. Take this formula at night and Tongqi San (Qi-Ventilating Powder) in the morning, one dose each, twice daily. Deafness lasting for thirty or twenty years can be cured.
Blood stasis in the subcutaneous layer: Taking three to five doses can prevent it from spreading; taking another thirty doses can lead to a cure.
Blood stasis in the dermal layer: The treatment method follows that of Vitiligo (Bai Dian Feng), and efficacy is invariably achieved promptly.
The face resembling a bruise from a blow, with purple patches covering the area or the entire face being purple, is caused by blood stasis. If the condition has persisted for three to five years, ten doses can cure it; if it has persisted for over ten years, twenty to thirty doses will certainly cure it.
Blood stasis syndromes often appear on the Tian Ting (Forehead/Upper Forehead region); thirty doses can cure them. Vitiligo, Purpura, Purple Marks, and Green Marks (Cyan Birthmarks/Spots) have lacked effective prescriptions since ancient times because the source of the disease was unknown.
Teeth are the surplus of bones; blood is what nourishes teeth. Shanghan, Wenyi, Variola (Smallpox), and Pi Kuai (Abdominal Masses) can all scorch the blood. Blood stasis turns the gums purple; blood death turns the gums black; blood death causes tooth loss. How can a person survive? Using cold-natured medicines to coagulate the blood further accelerates death. In such cases, take one dose of this medicine at night and one dose of Xuefu Zhuyu Tang (Drive Out Stasis in the Mansion of Blood Decoction) in the morning. During the day, decoct Huang Qi (Astragalus Root) eight qian, and consume it slowly throughout the day, finishing all three doses within one day. Effects can be seen in three days, significant improvement in ten days, and full recovery in one month. Even if five or seven teeth fall out, as long as the cheek does not perforate (gum ulceration leading to perforation), life can be saved.
