We are committed to science-backed solutions—and few natural ingredients have as much untapped potential as Propolis ACF®, our patented Bee Propolis Extract included in each of our Herstat branded creams and lip balms.
First patented in the 1970s, Propolis ACF® is the culmination of extensive study led by Dr. Zenon Sosnowski (MSc, PhD) into bee propolis and its potential benefits for human health.
A Legacy of Research
The benefits of Propolis ACF® were first noted in clinical investigations in the 1980s, where topical application of ointments containing this powerful extract showed promising results. More recent structured clinical trials have continued to confirm its healing and protective properties, cementing its role as a key ingredient in skincare and wellbeing.
But what makes Propolis ACF® so unique? The answer lies in its source and composition...
A Distinctly Canadian Propolis
Bees in Manitoba, Canada create propolis from an incredible variety of plant sources—over 230 different species contribute to this natural substance. Unlike other propolis from around the world, Manitoban propolis contains unique and highly active compounds, setting it apart as an exceptionally potent extract.
What’s Inside Propolis ACF®?
Propolis is composed of phenolics, powerful plant-derived substances that include flavonoids—compounds responsible for the vibrant red, orange, and yellow hues of fruit and autumn leaves. But their true value lies in their pharmacological benefits:
- Antiviral
- Antibacterial
- Anti-inflammatory
- Anaesthetic
- Healing (via enhanced cell metabolism and mitotic activity)
One of the standout compounds in Manitoban propolis is dihydrochalcones, a rare and highly valued subclass of flavonoids. These are particularly abundant in balsam poplars (Populus balsamifera)—a tree species native to Canada, which plays a crucial role in the region’s unique propolis composition.
The Role of Poplars in Propolis Production
Poplar trees are an integral part of the propolis story. These fast-growing trees thrive in the northern temperate regions of North America, Eurasia, and Africa. In Canada alone, poplars make up 11.6% of the nation’s tree population, covering over 45 million acres.
When bees in Manitoba produce propolis, they mix their saliva and wax with resins collected from local plant species, including:
- Poplar trees (notably balsam poplars)
- Clusia minor/rosea flowers
- Asteraceae family plants
This careful selection of resins results in a potent, plant-powered natural substance with remarkable properties.
Looking Ahead: The Future of Propolis ACF®
The benefits of Propolis ACF® extend far beyond its well-established healing properties. Ongoing research is exploring its potential applications in cosmetics and medicine, with exciting possibilities for skincare, immune support, and beyond.
At Dr. Sosnowski's we are proud to work with this unique ingredient in our Herstat products, refining it in our specialist laboratory in Winnipeg, Manitoba to bring you the very best in natural care.
