white willow bark salicylic acid powder
White Willow Bark Extract, also known as Willow Bark Salicin Powder or Salix Alba Extract. This extract has rich content of salicin, a natural precursor to salicylic acidthe compound that inspired the development of aspirin (acetylsalicylic acid). Upon ingestion, salicin is converted in the body to salicylic acid, delivering gentle yet effective anti-inflammatory, analgesic (pain-relieving), and antipyretic (fever-reducing) properties. Different from synthetic counterpart, this natural conversion process is often gentler on the stomach.
Key Bioactive Component: Salicin
The primary active component in White Willow Bark Extract is salicin (C₁₃H₁₈O₇, molecular weight 286.27). Its effects are not immediate but are sustained, as the metabolic conversion to salicylic acid occurs gradually over several hours. This makes it particularly valued for supporting comfort in cases of occasional joint discomfort, back discomfort, and overall inflammatory response related to physical activity.
We specialize in producing high-purity extracts with precise and consistent salicin standardization (from 15% to 98%). Our advanced HPLC/UV testing protocols ensure every batch meets stringent specifications for activity and low contaminants, providing you with a reliably effective raw material for your formulations.
Tailored OEM Solutions for Your Product Formulation: Whether you require a specific particle size for enhanced mixability in a drink powder, a particular extract ratio (like 5:1, 10:1, 20:1)for a capsule blend, or expert guidance on the optimal salicin concentration for your target market, we can develop a solution that fits your exact product requirements.
