Propolis is a by-product produced by honeybees. It is dropped by the bodies of active honeybees as they enter the hive, and requires a special 'trap' installed in the beehive to collect it. We are not large enough an operation to make this practical.

If you are looking to purchase Propolis in Ottawa, try to ascertain its source. There are many, many countries exporting honey and honey bi-products who have no federal health-inspection laws in place, and whose honey is boiled, sugarized, blended, dyed, and watered down, making it highly suspect, to say the least.
We occasionally have Propolis in small amounts. Best to call ahead.
