The European and Austrian Pharmacopoeia includes many medicinal plants and their active ingredients. It defines a minimum active substance concentration for recorded medicinal herbs, which must be contained in each case, as well as the purity of the active substances contained. With regard to the desired effect and quality of our products, we always process medicinal herbs of pharmacopeia quality, if available. For raw materials that are not available in pharmacopoeial quality (e.g. if a drug is not included in the pharmacopoeia), we process medicinal plants of organic quality.
