Gum guaiac is a natural resin widely used in the food industry as an antioxidant to prevent oxidation of fats and oils, extending product shelf life. In pharmaceuticals, it provides anti-inflammatory and expectorant properties, commonly found in cough syrups and throat lozenges. As an analytical reagent, it is key in the guaiac test for detecting occult blood and peroxides via color change in forensic and medical applications. It is also used in manufacturing adhesives and varnishes for its binding qualities. In traditional medicine, gum guaiac treats digestive disorders, skin conditions, and acts as a laxative due to its soothing effects.
