Propolis is a natural antibiotic. Our High Potency Propolis Tincture is a solution of half pure propolis and half neutral grain spirits. Most propolis tinctures available have no more than 20 percent propolis. This means that with our product, a little will go a long way.. And our newest batch of propolis has been made with Non-GMO Neutral Grain Spirits. Propolis Tincture creates a protective coating over the affected area while healing at the same time. Three to four drops should be enough to soothe most sore throats, sores in the mouth and open cuts on the skin. Over 200 doses per one ounce bottle. Propolis has been known to be a healing substance since ancient times; Aristotle mentions propolis in his “Story of the Animals” and considered it to be a useful remedy for wounds, infections and skin ailments. The recognized antibiotic and antibacterial properties of propolis benefit the bees and their hive in a myriad of ways.
