Its extract has an inhibitory effect on common pathogenic bacteria such as Staphylococcus aureus and Streptococcus, thanks to itsTanninandPhenolic components. Folks often pound the fresh leaves and apply them externally to treat skin infections, or boil them in water and take them orally to relieve inflammation. Studies have shown that its antibacterial effect is equivalent to that of some synthetic antibiotics, but it should be noted that long-term use may affect the balance of intestinal flora.

Application for promoting blood circulation and removing blood stasis and bruises

Lambuzheng's blood-activating effect makes it a commonly used herbal medicine for bruises. It can promote local blood circulation, accelerate the dissipation of congestion, and relieve swelling and pain. Ethnic minorities in Guizhou and other places often brew it with wine to make medicinal wine for external use, which can be used for sprains or joint pain. Animal experiments show that its extract can reduce blood viscosity and inhibit excessive platelet aggregation, but pregnant women and patients with bleeding disorders should use it with caution.

Antioxidant and auxiliary regulating function

Blue cloth in the middleflavonoids(such as quercetin) has the effect of scavenging free radicals and can delay oxidative damage to cells. A small-scale study on middle-aged and elderly people showed that after taking Lanbu Zheng tea for 8 weeks, the subjects’ serum antioxidant index increased by about 15%. In addition, its mild diuretic effect may be beneficial in assisting the regulation of hypertension, but it cannot replace regular antihypertensive drugs.

Suggestions and precautions for use

Lanbuzheng is mostly used in the form of decoction (5-10g/day) or external application. Avoid taking it with cold and cooling drugs. People with weak constitution may suffer from diarrhea, so it is recommended to mix it with ginger. Although safety is high, you still need to pay attention to:①Pregnant women are prohibited from using blood-activating functions;②Long-term use requires monitoring of liver function;③People with allergies need to test a small dose before using it for the first time. Taken together, Lanbuzheng has both practicality and research potential as a traditional herbal medicine, but it should be used scientifically.
