What is Naringin?
Naringin, also known as naringin, citrus glycoside, or isohesperidin, is mainly found in the skin and flesh of grapefruit, orange, and tangerine plants in the Rutaceae family. Naringin is also the main active ingredient in Chinese herbal medicines such as bone broken tonics, Fructus Aurantii, Fructus Aurantii, and Orange Red. The content of naringin in various plants varies greatly depending on the variety and place of origin, with immature fruits usually having higher content. Naringin Powder is a purified form of this bioactive compound, widely used in the food, pharmaceutical, and cosmetic industries due to its antioxidant, anti-inflammatory, and metabolic-regulating properties.
