Propolis Used to Treat Colds, Rheumatism, Diabetes, Stomach Pain


Searching for bioactive compounds from Vietnamese propolis

Propolis is biologically a mixture of sap with secretions from the bee's salivary glands, which is used to seal the hive, help preserve honey, protect the development of larvae, eggs and itself from the attack of pathogens.

Among bees, Italian bees (Apis melifera, Apini tones) and Du wasps (also known as stingless bees) (Meliponini tones) give much propolis and have drawn interest from researchers. Unlike Italian bee Apis melifera, the Du is rich in number of species, with more than 500 species in the world, distributed in many different geographical areas. In Vietnam, according to previous studies, there are more than 10 different species of the Du.

Propolis has long been used in the treatment of colds, rheumatism, diabetes, stomach pain, and has many biological activities that have been discovered such as antibacterial, antioxidant, anti-cancer and anti-HIV. Due to many practical applications such as medicine products and functional foods, propolis has attracted a lot of research on chemical composition and biological activity.

Currently, scientists have isolated more than 500 compounds in honey propolis as well as Du propolis in the world. The chemical composition of propolis includes phenolic acid compounds, phenolic esters, flavonoids, triterpenes, stilbenes and prenyl flavanoids. However, there has not been much research on the chemical and biological activity of propolis in Vietnam...
