II. Product Introduction
1. Source
Usnea Extract—98% Usnic Acid—is refined from the whole plant of Usnea longissima Ach., a species belonging to the genus Usnea within the family Parmeliaceae. The production process involves several steps, including careful selection of raw materials, washing, grinding, three-stage extraction, concentration, purification, crystallization, drying, sieving, and sterilization. Through a scientifically optimized extraction and purification process, this product maximizes the preservation of the active ingredients’ structure and efficacy. Usnea is primarily found in high-altitude forests across northeastern, northern, northwestern, and southwestern regions of China, where the raw materials exhibit excellent quality.
2. Core Efficacy and Applications
(1) The pharmaceutical field
Lichenic acid, a key component of lichen extracts, exhibits potent antibacterial and antiviral activities, effectively inhibiting or killing a wide range of bacteria, fungi, and viruses. It also demonstrates certain anti-inflammatory and analgesic effects. Based on these properties, lichenic acid can be used as an ingredient in the production of antimicrobial, antiviral, and anti-inflammatory pharmaceutical products, such as topical ointments, gels, and washes, for the treatment of skin infections and mucosal inflammations.
(2) Cosmetics field
The antibacterial and anti-inflammatory properties of usnic acid make it widely applicable in the cosmetics industry. It can be incorporated into skincare products, shampoos, body washes, and other formulations to help inhibit the growth of harmful bacteria on the skin surface and prevent skin problems such as acne and dermatitis. Meanwhile, its antioxidant effects protect skin cells from damage caused by free radicals, making it suitable for a variety of cosmetic formulations including lotions, creams, serums, and acne-fighting products.
(3) The field of feed additives
Clavulic acid exhibits antibacterial and growth-promoting effects, making it suitable as a natural feed additive in the livestock and poultry farming industry. It helps enhance the immune system of livestock and poultry, prevent diseases, and promote growth and development, aligning with the trend toward green animal husbandry.
(4) Research Field
As a biochemical reagent, it can be used in studies on the antibacterial mechanisms related to usnic acid, antiviral mechanisms, pharmacological effects, and other research areas, providing support for fundamental research in fields such as pharmaceutical sciences, veterinary medicine, and cosmetic science.III.
