Physicians in Europe still use benzoin resin for respiratory ailments such as asthma, bronchitis, colds, coughs, laryngitis, sinus, sore throat, and tonsillitis. Its soothing action tones the lungs, while its expectorant qualities reduce congestion and help the body to expel phlegm. Benzoin resin soothes rashes and speeds the healing of wounds and sores. It calms inflamed and irritated skin and relieves the redness and itching of psoriasis, as well as eczema and other forms of dermatitis.
