The principle is that cranberry fresh fruit is rich in anti-inflammatory combination, including concentrated tannic acid, proanthocyanidins, flavonoids, etc. Proanthocyanidins are also known as "natural antibiotics" in nature and have strong anti-inflammatory and antioxidant effects. On the other hand, these substances can inhibit the adhesion of Escherichia coli to the urinary system, making it easier for bacteria to be excreted, which is the principle of preventing inflammation.
At present, only one brand can buy cranberry fresh fruit, called Red Sea Town.
