Salix Alba

The main components of Salix alba (Willow tree) areSalix alba salicylates: derivates of salicylic acid, and precursors of aspirin. In addition to salicylic acid derivates, Salix alba also contains high levels of polyphenols which are transformed into salicylic acid through the metabolism of the animal. Salicylic acid is a strong painkiller (analgesic), reduces fever (antipyretic), and has an anti-inflammatory effect.


The citrus extracts in Aspitop are a source of strong antioxidants with ascorbic acid, bioflavonoids, and polyphenols as the main components. These citrus extracts support the immune system, reduce stress, protect the liver and act as anti-inflammatory agents


Propolis is a natural ingredient produced by honey bees.Propolis It contains high levels of polyphenols and flavonoids that have a strong antibacterial and anti-inflammatory action.
