Has the ability to protect vision and prevent blindness; Strengthen cerebral vessels, prevent cerebral vascular diseases, strengthen myocardial vessels, strengthen coronary arteries, strengthen renal vessels, prevent hematuria, urethritis and cystitis caused by glomerular capillary rupture; Strengthen veins, prevent varicose veins, prevent ulcers; Prevent arteriosclerosis; Preventing the formation of blood clots.

Efficacy and function

1, antioxidant effect: Baisfu Bilberry Extract are natural water-soluble free radical scavengers, and their antioxidant activity is 20 times that of VC and 50 times that of VE. Blueberry anthocyanins have the ability of anti-liposome peroxidation, reducing ability and scavenging superoxide anion free radical and hydroxyl free radical. Flavonoids from blueberry residue had strong antioxidant capacity, especially after purification, the antioxidant capacity of flavonoids was enhanced, and the DPPH scavenging capacity of total phenol from blueberry residue was 26.7mgVc/g fresh weight. The scavenging ability of oxygen free radical was 24.8mgVc/g fresh weight. Blueberry polysaccharide has strong scavenging ability on oxygen free radical and DPPH.
2, antibacterial, anti-inflammatory and analgesic effects: Blueberry extract can inhibit the growth of harmful bacteria and promote the proliferation of beneficial bacteria. The results showed that blueberry extract had inhibitory effect on Escherichia coli, Staphylococcus aureus and Vibrio parahemolyticus, and adding proper concentration of blueberry extract to fermented milk could promote the growth of Lactobacillus acidophilus in vitro. The study of Wang Jing et al. confirmed that blueberry anthocyanins can increase the pain threshold and inhibit the swelling of the auricle in mice, and have obvious analgesic and anti-inflammatory effects.
