Hydro-ethanolic refers to a solution or mixture that consists of water (hydro) and ethanol (ethanolic), typically used in various applications, including extraction processes in herbal medicine and laboratory settings. This combination leverages the solvent properties of both water and ethanol to effectively dissolve a range of polar and non-polar compounds, enhancing the extraction of active ingredients. Hydro-ethanolic solutions are often preferred for their ability to preserve the bioactivity of certain compounds while being relatively safe for consumption.
