Olbas Inhalant Decongestant Oil is a concentrated blend of pure plant oils formulated to relieve nasal congestion, blocked sinuses, catarrh and discomfort associated with colds. The formula combines eucalyptus oil, cajuput oil, partly dementholised mint oil, juniper berry oil, clove oil, levomenthol and methyl salicylate. Eucalyptus, mint and cajuput oils release aromatic vapours that support clearer breathing and provide a cooling sensation, while levomenthol contributes to the refreshing decongestant effect. The oil can be inhaled from a tissue or added to hot water as directed, making it suitable for daytime or nighttime relief. It may also be applied externally as directed for the symptomatic relief of minor muscular aches and discomfort.
