Essential oils are now widely used in hospitals, by doctors and many aromatherapists as part of aromatherapy. The medicinal effect of many naturally pure plant oils has already been proven in many studies. When selecting our essential oils, we concentrate on a range of plants that have proven their medical effect through studies and our experience in our pharmacy. Therefore, when selecting our suppliers, we attach great importance to high and 100 percent natural quality, without additives and rely exclusively on natural products from controlled organic cultivation. Saint Charles natural essential oils are therefore also bottled in high-quality and shelf-stable violet glass bottles (20ml).
