It was used as a antitussive and antipyretic agent, active against different types of mild respiratory damages. The drug contained four active principles: (i) an essential oil derived from the plant Myrtus communis L. (myrtle oil), (ii) Eucalyptus oil which has an anti-inflammatory effect, (iii) camphor and (iv) Na thiophene-2-carboxylate, a compound acting as a mucoregulator to facilitate expectoration. The product is no longer used today but other drugs containing M. communis essential oils can be found, acting notably as natural antioxidants.
