What is propolis, and what is it used for?
Propolis is a natural adhesive and resin-like substance produced and used by bees to construct and repair their hives. Honeybees produce propolis by collecting pollen, resin, and other substances from various plants such as poplar and coniferous trees and mixing it with beeswax and salivary enzymes they secrete. Propolis is a complex mixture of several chemicals and has been used as traditional medicine since ancient times to treat several ailments.
Ancient Egyptians used propolis for mummification, Incas used it to treat fever, and Greek and Roman physician used it as a mouth disinfectant and as an antiseptic and healing agent in wound treatment. People have since used propolis for various conditions including tuberculosis, inflammatory skin conditions, rheumatism, peptic ulcers and other gastrointestinal conditions. The famous crafter of string instruments Antonio Stradivari used propolis as an ingredient in the varnish of his instruments, and it is still used in rosin for stringed instruments.
The chemical composition of propolis is highly variable depending on the geographical origin, vegetation, and seasons, and it is difficult to standardize the product. Generally, propolis contains resins, waxes, essential oils, pollen and other organic compounds, and studies have identified more than 300 compounds in propolis samples. Some of the bioactive components of propolis include polyphenols, flavonoids, terpenes, and aromatic acids. Propolis also contains several trace minerals, vitamins, fatty acids, enzymes, and sugars.
Studies of propolis indicate it has antioxidant, anti-inflammatory, antibacterial, antiviral, antifungal, immunomodulatory, and antitumor properties. Although many therapeutic compounds have been identified in propolis, there are no controlled clinical trials in humans to establish their efficacy in any of its uses. Propolis, however, is generally considered safe and nontoxic. It is commercially available in the form of capsules, mouthwash solutions, throat lozenges, powder and topical formulations such as ointments, creams, and lotions.
