Traditional applications and symptoms

The efficacy and function of Yuanhu

Yuanhu is recorded in traditional Chinese medicine classics as a "blood qi medicine" and is good at treating various types of pain caused by qi stagnation and blood stasis. For example, "Compendium of Materia Medica" states that it "specializes in treating various pains throughout the body" and is often used forStomach pain, dysmenorrhea, postpartum stasisAnd rheumatic arthralgia. In terms of compatibility, it can be used with Cyperus rotunda and Angelica sinensis to enhance the effect of regulating menstruation; it can be used with Wulingzhi to treat pain in the heart and stomach. Its analgesic mechanism is related to suppressing central nervous system sensitivity, and its side effects are small, making it suitable for short-term symptomatic use.

Modern pharmacology and scientific verification

Studies have found that Tetrahydropalmatine, the analgesic component of Yuanhu, can block dopamine receptors and reduce pain signal transmission. Animal experiments show that its extract inhibits the writhing reaction in mice induced by acetic acid.More than 60%(See table below). In addition, Yuanhu can expand coronary arteries and improve myocardial blood supply, which has certain potential for auxiliary treatment of angina pectoris. However, it should be noted that long-term use of large amounts may cause dizziness or digestive tract discomfort.

Precautions and contraindications for use

Although Yuanhu is a natural medicinal material, it should be used with caution by pregnant women, people with menorrhagia and patients with low blood pressure to avoid aggravating bleeding or causing dizziness. Recommended when decoction3-10 gramsIt is appropriate. Excessive dosage may inhibit the respiratory center. In addition, there should be a 2-hour interval between combined use with Western analgesics to prevent component interaction. Li Shizhen, a physician in the Ming Dynasty, once warned: "You cannot take Corydalis Corydalis for a long time, as it may deplete your true energy", emphasizing the principle of stopping the disease immediately.

Summary and reasonable application suggestions

Taken together, Yuanhu is a good analgesic medicine supported by both traditional experience and modern science, especially suitable for pain caused by qi stagnation and blood stasis. Syndrome differentiation and treatment are required during use, and short-term symptomatic effects are better. For patients with chronic pain, it is recommended to combine it with other blood-activating drugs under the guidance of a physician to avoid sole dependence. It is relatively safe, but special groups of people should strictly follow the taboos to ensure that the medication is reasonable and effective.
