APOTHEKERSERIE OIL MIXTURESThe Apothecary Series products are blends of 100% naturally pure essential oils for a wide variety of uses. All are popular formulations from the Saint Charles Apothecary. When selecting our essential oils, we focus on a range of plants that have been proven through studies and our experience in our pharmacy. Thus, when selecting our suppliers, we also attach great importance to high and 100 percent natural quality, without additives and rely exclusively on natural products from controlled organic cultivation. The blends of the apothecary series are therefore also bottled in high-quality and shelf-stable violet glass bottles (20ml) .
