Propolis drops are a liquid propolis extract, a resinous substance that bees produce by combining plant resins with their own enzymes. These drops are renowned for their antibacterial, antiviral and anti-inflammatory properties, and are often used as a food supplement or natural remedy to support the immune system and general health. Propolis drops can be taken orally or applied topically to the skin, making them a popular product in natural medicine and alternative therapy.
