Though they are of different families, Salix Alba (White Willow) and Salix nigra (Black Willow) are often used interchangeably due to their strikingly similar uses and composition. The Black Willow or Salix nigra is a medium-sized deciduous tree, the largest North American species of willow, growing from 10-30 m tall with long, alternating, shiny green and narrow lanceolate leaves. Although named Black Willow, the bark of most specimens is dark brown or grey, becoming fissured on older trees. The willow's root strength and general resilience are but a few of the qualities that highlight it as the most commercially and economically important member of the Salix genus.
Within the cosmetics industry, Willow Bark Extracts are employed as a natural source of Salicylic Acid. As reported at the Society of Investigative Dermatology, Willow Bark Extract provides the benefits of Salicylic Acid such as exfoliation, and anti-microbial action, without any of the typically associated irritation from the active alone. Willow Bark Extract has solidified itself as one of the principal herbal remedies to treat pain and act as an anti-inflammatory analgesic agent.
Willow Bark Extract is standardized for 9.8 - 11.5% natural salicylates and provides formulators with the perfect alternative to synthetic Salicylic Acid products. This product is ideal for reducing inflammation and associated redness and it acts as an efficacious antimicrobial. This water-soluble extract promotes seamless incorporation into a variety of formulas promoting all of the benefits associated with Salicylic Acid and none of the irritation. Clinical tests have also shown Black Willow Bark Extract to have activity against Staphylococcus aureus and Propionibacterium acnes, the two strains of bacteria implicated in the formation of acne, as such it may prove useful in targeted facial cleaners, toners and lotion formulas.
