Hydrosols, also known as "flower waters," are produced by distilling fresh leaves, fruits, flowers, and other plant materials. With similar properties to essential oils, these aromatic waters are much less concentrated. Their aromas are often soft and subtle when compared to their essential oil counterparts.
Carrier oils are pressed from the fatty portions (seeds, nuts, kernels) and do not evaporate or impart their aroma as strongly as essential oils. Carrier oils can go rancid over time, but essential oils do not. Instead, essential oils "oxidize" and lose their therapeutic benefits, but they don't go rancid.
Essential Oils are concentrated liquefied extracts containing the volatile aromatic compounds from plants, flowers and trees. Pure Essential Oils contain numerous complex components that often cannot be replicated in a lab, which makes them powerful tools for healing and well-being.
