Sinus clear is a specially formulated decongestant blend that is supplied with a personal aroma inhaler.  It contains eucalyptus, tea tree, peppermint and lavender.  These oils are useful for allergies, coughs and colds, and have properties which complement each other.  This formulation is suitable for use in an electric or candle diffuser, or to replenish the absorbent pad inside your personal inhaler.  As these oils are concentrated, it is recommended you dilute with a suitable carrier oil prior to skin application.
