Overview of the efficacy and functions of Liu Jinu

Liu Jinu, also known as Liuyue Xue and Jin Jinu, is a medicine commonly used in clinical Chinese medicine to activate blood circulation and remove blood stasis. It has the functions of breaking blood and promoting menstruation, dispersing blood stasis and relieving pain, and digesting food and resolving accumulation. Its core functions are reflected in three aspects: first, it is used for gynecological blood stasis syndrome, such as amenorrhea and dysmenorrhea; second, it treats bruises, blood stasis, swelling and pain; third, it assists in improving abdominal distension due to food accumulation. Modern research has also discovered its anti-inflammatory, antioxidant and other potential values. This article will focus on its main effects, combine traditional applications and modern scientific basis, and systematically analyze the medicinal value of Liu Jinu.

Promotes blood circulation and removes blood stasis, a good medicine for gynecological blood stasis syndrome

Liu Jinu is widely used in the field of gynecology, and is especially good at regulating amenorrhea, dysmenorrhea and postpartum lochia caused by blood stasis. "Rihuazi Materia Medica" records that it "opens the meridians of women and is the crux of the disease". Its active ingredients such as flavonoids and volatile oils can promote blood circulation and relieve uterine spasm pain. Clinically, it is often combined with Angelica sinensis and Ligusticum chuanxiong to enhance the curative effect. It should be noted that pregnant women and those with heavy menstruation should use it with caution to avoid aggravating the risk of bleeding.

Natural pain reliever for bruises

For blood stasis, swelling and pain caused by trauma, Liu Jinu has a significant effect when applied externally or taken internally. "Compendium of Materia Medica" calls it "dispersing blood and reducing swelling". Modern research shows that its extract can inhibit the release of inflammatory factors and reduce tissue edema. It is commonly used among the people to pound the fresh product and apply it externally, or mix it with safflower, frankincense, etc. to make medicinal wine and apply it on it. Typical usage: 15 grams of Liu Jinu, mixed with 3 grams of Panax notoginseng powder, decoction in water, one dose per day for 3-5 consecutive days can improve acute soft tissue injuries.

Auxiliary conditioning effect for digestion and digestion

The digestive effect of Liu Jinu is often overlooked, but it actually has a unique effect on food stagnation and abdominal distension. "Compendium of Materia Medica" points out that it is "eliminating food". Its bitter component can stimulate gastric juice secretion and accelerate gastrointestinal motility. For those with mild food accumulation, 10 grams of Liujinu can be decocted with hawthorn and malt instead of tea. However, it needs to be distinguished from digestive drugs such as Jiao Sanxian. Liu Jinu is more suitable for indigestion with signs of blood stasis, such as dark purple tongue and astringent pulse.

Summary and scientific understanding

As a traditional blood-activating medicine, Liu Jinu's value lies in regulating blood stasis-related diseases with multiple targets. Modern pharmacology has confirmed that the coumarin, polysaccharides and other ingredients it contains have anti-platelet aggregation and improved microcirculation effects. When using it, treatment should be based on syndrome differentiation: it is suitable for patients with blood stasis, and those with weak qi and blood need to be combined with tonic drugs. Future research can further explore new uses such as its anti-fibrosis and protection of vascular endothelium, but it must follow the principle of traditional Chinese medicine that "a medicine has its own unique characteristics before it can be used in a gregarious manner".
