Traditional applications and main functions

In folk medicine, open arrows are widely used to relieve throat ailments.Its name comes from the improvement of the symptoms of "difficulty opening the throat" and is often used in the form of decoction or external application.For example, the Zhuang people in Guangxi use its rhizomes soaked in wine to treat rheumatism pain, while in Yunnan they crush it and apply it externally to reduce swelling.Traditionally, it is believed that it is cool in nature and bitter in taste, and it returns to the lung and liver meridians, making it suitable for patients with heat syndrome.It should be noted that its use requires syndrome differentiation and treatment to avoid misuse by those with weak constitution.

Modern pharmacological research and mechanism of action

Recent studies have found that flavonoids (such as quercetin) in open arrows have significant anti-inflammatory effects, inhibiting prostaglandin synthesis and reducing redness, swelling, heat and pain.Animal experiments show that its extract has an inhibitory rate of 65% and 48% against Staphylococcus aureus and Escherichia coli (see table below).In addition, its saponin component can promote local blood circulation and accelerate tissue repair, which provides scientific basis for its application in bruises.
