Propolis is a resinous substance collected by bees off plant buds and used to protect the hive from external aggressions. Here we blend it with Echinacea and various essential oils to provide a product which will serve to enhance the body's immune system, and help defend it against the microbes which attack the ears, nose and throat. Ingredients: Propolis, Echinacea, Essential oils of Cimbopogon Citratus (Lemongrass), Cinnamomum Zeylandi (Cinnamon), Melaleuca altern. (Tea Tree), Quinquin, and Eucalyptus rad. (Eucalyptus) Other Ingredients: Alcohol (50% Vol) Suggested Use: For adults, 2-3 pump strokes several times per day
