Propolis is a substance made by bees from the resinous components of plants. Propolis consists of resins, balsams, essential oils and organic matter, including flavonoids such as galangin and quercetin. We have selected a glycerinated extract of Propolis with a 1:31 ratio. This means that for every gram of extract, 31 grams of Propolis have been used. Our glycerinated extract of Propolis is titrated in Galangin 5 mg/ml, providing 15 mg per day.
