The Science behind Propolis: Understanding Its Composition and Properties

Propolis is a sticky substance that is produced by bees and is commonly known as “beeglue”. It is made from tree sap, resins, and other substances that bees collect from plants and trees. Propolis is used by bees to seal up cracks and holes in their hives, and it also helps to protect the hive from bacteria and other harmful organisms. It has been used for centuries for its medicinal properties and is often found in natural health products. In this article, we will explore the science behind propolis, including its composition and properties, as well as the benefits and uses of propolis.

Composition of Propolis

Propolis is made up of a complex mixture of compounds, including flavonoids, phenolic acids, and terpenes. The composition of propolis can vary depending on the specific plant sources available to the bees. These compounds are found in varying amounts depending on the geographic location of the bees and the plants they collect resin from.

One of the main constituents of propolis is flavonoids, which are a group of plant compounds that have antioxidant properties. Flavonoids found in propolis include pinocembrin, galangin, chrysin, and quercetin. Phenolic acids, such as caffeic acid, are also present in propolis, which are known for their anti-inflammatory properties. Terpenes, such as beta-caryophyllene, are present in small amounts and are known for their antimicrobial properties.

Properties of Propolis

Propolis has some properties that make it useful for medicinal purposes. It has been found to have antimicrobial, anti-inflammatory, antioxidant, and immunomodulatory effects.

The antimicrobial properties of propolis are due to the presence of flavonoids and other compounds that can inhibit the growth of bacteria, viruses, and fungi. This makes it useful for treating infections and preventing the growth of harmful microorganisms.

The anti-inflammatory properties of propolis are due to the presence of phenolic acids, which can help to reduce inflammation in the body. This makes it useful for treating inflammatory conditions such as arthritis and asthma.

The antioxidant properties of propolis are due to the presence of flavonoids, which can neutralize free radicals in the body and prevent oxidative damage to cells. This makes it useful for preventing chronic diseases such as cancer and cardiovascular disease.

The immunomodulatory effects of propolis are due to the presence of compounds that can stimulate the immune system and enhance immune function. This makes it useful for preventing and treating infections, as well as for boosting overall immunity.

Benefits and Uses of Propolis

Propolis has a wide range of potential benefits and uses due to its various properties. Some of the most common uses of propolis include:

  • Strengthening the immune system
  • Treating colds and flu
  • Reducing inflammation and pain
  • Protecting against oxidative stress and free radical damage
  • Preventing and treating infections
  • Supporting oral health by reducing plaque and gingivitis

Propolis can be found in a variety of forms, including natural propolis powder, capsules, and extracts. Its antimicrobial properties and ability to inhibit the growth of bacteria associated with dental issues. It can be taken orally, applied topically, or used as a mouthwash.


Propolis is a natural substance with a complex composition and a wide range of potential health benefits. Its antimicrobial, anti-inflammatory, antioxidant and immunomodulatory properties make it useful for treating and preventing a range of conditions. Propolis may be a useful addition to your health routine. When using propolis, individuals should always consult with a healthcare professional before adding a new supplement to their routine, especially if they have underlying health conditions or are taking medications.
