White Willow Bark Extract is derived from the bark of the white willow tree (Salix alba L.), a botanical often referred to as “Nature’s Aspirin.” It has been used for centuries to manage pain and inflammation. The extract contains a potent active compound called Salicin, which the body naturally converts into salicylic acid. Unlike synthetic aspirin, White Willow Bark Extract offers a gentler mechanism of action with fewer gastrointestinal side effects.
Typically appearing as a brown-yellow to light brown fine powder, it is standardized to specific concentrations of Salicin, commonly ranging from 15% to 98%. Due to its dual benefits for internal health (joint pain, fever) and external beauty (exfoliation, anti-acne), it is a versatile ingredient. As a professional White Willow Bark Extract supplier and manufacturer, we provide high-purity, HPLC-tested extracts suitable for pharmaceuticals, nutraceuticals, and cosmetic formulations.

What is Salicin?
Salicin is a naturally occurring glucoside found in willow bark. When ingested, it is metabolized into salicylic acid, which is responsible for the anti-inflammatory and pain-relieving effects.
Is this the same as Aspirin?
Chemically, aspirin is acetylsalicylic acid (synthetic), while White Willow Bark contains salicin. While they act similarly, the natural extract is often slower-acting but longer-lasting and is generally considered to have a lower risk of irritating the stomach lining.
Can this extract be used in cosmetics?
Yes, it is extremely popular in the cosmetic industry. White Willow Bark Extract is standardized for Salicin, which provides beta-hydroxy acid (BHA) activity—exfoliating dead skin cells and clearing pores without the harshness of synthetic salicylic acid.
What creates the different colors of the powder?
Lower concentrations (e.g., 15-25% Salicin) are typically brown-yellow herbal powders. High-purity extracts (e.g., 98% Salicin) are white crystalline powders. We offer both grades depending on your formulation needs.
Is your product water-soluble?
Yes, our White Willow Bark Extract has good water solubility, making it suitable for beverages, tinctures, and water-based cosmetic serums.
