A team of researchers from the University of Chemistry and Technology in Prague has developed a novel method to enhance the natural healing properties of bee propolis, a potent remedy known for its antibacterial, antioxidant, and anti-inflammatory effects.<\/p>\n

By encapsulating propolis extract within porous particles derived from common baker’s yeast, the scientists have successfully overcome propolis’s main limitation\u2014poor water solubility. This new composite material was shown to be significantly more powerful at fighting inflammation and microbes than propolis alone.<\/p>\n

The findings, published<\/a> in the Journal of Drug Delivery Science and Technology, detail research that could lead to a new generation of highly effective, naturally-based therapies.<\/p>\n

Propolis is a resinous substance that honeybees produce to protect their hives from diseases. It is a complex mixture of hundreds of beneficial compounds, including flavonoids and phenols, which have well-documented health benefits.<\/p>\n

Propolis’s limitations and the new solution<\/p>\n

“For centuries, humans have used propolis as a powerful natural medicine,” said Ad\u00e9la Brejchov\u00e1 and Eva Kr\u00e1lov\u00e1, the lead authors on the study.<\/p>\n

“However, its effectiveness has always been limited because it’s waxy and doesn’t dissolve in water, meaning our bodies can’t easily absorb it. Most of its healing potential is locked away,” added Dr. Denisa Lizo\u0148v\u00e1, a co-author of the study.<\/p>\n

The research team’s innovative solution was to find a natural “carrier” to deliver the propolis. They turned to an inexpensive and safe source: baker’s yeast (Saccharomyces cerevisiae). Through a multi-step process, they extracted the yeast’s tough outer cell wall, creating hollow, porous “glucan particles” (GPs) that act like microscopic sponges.<\/p>\n

They then used an advanced spray-drying technique\u2014patented by UCT Prague\u2014to successfully load the propolis extract directly into these particles.<\/p>\n

\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tEnhanced bioactivity and wound healing results<\/p>\n

The study confirmed that this method was highly efficient, creating a stable, amorphous powder where the propolis was ready to be released. When tested, the new propolis-loaded glucan particles (GPs\/PP) far outperformed pure propolis extract.<\/p>\n

The GPs\/PP composite released propolis rapidly, creating a “supersaturated solution” that delivered a much higher concentration of propolis’s active compounds than pure extract ever could in water.<\/p>\n

The encapsulated propolis effectively reduced key inflammatory markers (like NO and IL-6) at levels comparable to propolis dissolved in harsh organic solvents. This demonstrates a significant increase in usable bioactivity.<\/p>\n

The new composite showed a vastly improved ability to kill the yeast Candida albicans and the “superbug”-related bacterium Staphylococcus aureus compared to propolis alone.<\/p>\n

In a lab model<\/a> simulating a wound, the GPs\/PP 3 composite promoted 100% wound closure within 48 hours. In contrast, propolis extract dissolved in ethanol (the base for many commercial tinctures) failed to fully close the wound even after 72 hours.<\/p>\n

Implications for future therapies<\/p>\n

Such advanced bioactivity tests were possible thanks to state-of-the-art facilities at the Department of Biochemistry and Microbiology, operated by Prof. Jitka Viktorov\u00e1 who collaborated on the research.<\/p>\n

“We’ve essentially created a delivery system that tricks propolis into dissolving in water, making it much more bioactive at lower concentrations,” explained Professor Franti\u0161ek \u0160t\u011bp\u00e1nek, a lead researcher on the project.<\/p>\n

“The glucan particle itself is also beneficial, as it can interact with the immune system. This combination creates a synergistic effect where the whole is greater than the sum of its parts. By solving the solubility problem, we’ve made propolis a much more effective and viable therapeutic.”<\/p>\n
