Usnic Acid Powder is a furandione compound that occurs abundantly in lichen genera such as Alectoria, Cladonia, Usnea, Lecanora, Ramalina, and Evernia. It is widely incorporated into cosmetics, deodorants, toothpaste, medicinal creams, and various herbal products—serving either as a core active functional ingredient or a preservative depending on the application. Under standard ambient conditions, usnic acid exists as a bitter-tasting, yellow solid substance. Research has confirmed that it exhibits antiviral, antiprotozoal, antiproliferative, anti-inflammatory, and analgesic activities. Additionally, it boasts ecological effects including growth inhibition, herbivore deterrence, and insect-repellent properties.
