What is Quercetin Capsules ?
Quercetin (quercetin) is a kind of plant flavonoids, which has antitussive and antiphlogistic effects and is often used in the treatment of chronic tracheitis .
Quercetin itself has two molecules combined with water complex (Capsules): C15H10O7 + 2H2O, so quercetin Capsules is a more strict name for quercetin API. However, in the determination of quercetin content, the content of anhydrous quercetin should be calculated, that is to say, the binary water should be removed from the calculation.
