Eutherol Ear Nose & Throat Tonic combines menthol, licorice root, essential oils and a small amount of iodine in a soothing glycerine base. Menthol helps give the formula its clearing feel, licorice is a traditional herb for throat and mucous membrane comfort, and the essential oils are there to freshen and open the upper airways.
The broad oil blend matters because different oils contribute different qualities. Eucalyptus and peppermint are commonly used for a cooling, clearing effect, clove and rosemary add a warming aromatic edge, and citrus oils help freshen the blend. Eutherol is best understood as a targeted upper respiratory tonic for the nose, throat and sinus area.
