Herbal Oils are used to coat an area for more prolonged use or to massage a larger area. Oils work well with pulling the properties from herbs and penetrating the skin with massage for a soothing feeling. Oils do leave a residue until completely absorbed, but Dimmak Oils contain high quality oils and added Vitamin E for longer shelf life and a moistening action on the skin.Notice our oils contain a list of herbs that are extracted in the herbal oils not just additives to them!
