  • Immuno-stimulating properties are derived from the polysaccharides and volatile oil.
  • Anti-fungal properties are only found in a tincture. It is the resin, myristic & palmitic esters which are anti-fungal (resin requires 90% EtOH for extraction).
  • Vulnerary actions are due to the xanthophyls (which stimulate granulation tissue), mucilage and volatile oils.
