Viridian’s white willow has been certified organic by the Soil Association to make a supplement that is better for both you and for the planet.
White willow bark contains an active ingredient called salicin, which can be converted by the body into salicylic acid. The first aspirin (acetylsalicylic acid) was made from a different salicin-containing herb, meadowsweet, which works in a very similar way. Although all aspirin is now chemically synthesized, it is not surprising that white willow bark is often colloquially referred to as ‘herbal aspirin’.
