A green method for determination of ethanol in homeopathic medicines using thermal infrared enthalpimetry.In this work, a simple and fast method is proposed for the determination of ethanol in homeopathic medicines using thermal infrared enthalpimetry (TIE). 
thermal infrared enthalpimetry
Purified water or absolute ethanol was added directly into homeopathic medicine and increase of temperature was monitored using an infrared camera.
