Pro + polis

Propolis is a resin-like material made by bees from the buds of poplar and cone-bearing trees. Bees use it to build hives, and it may contain beehive byproducts.

Propolis seems to help fight against bacteria, viruses, and fungi. It might also have anti-inflammatory effects and help skin heal. Propolis is rarely available in its pure form. It's usually obtained from beehives.

People commonly use propolis for diabetes, cold sores, and swelling and sores inside the mouth. It's also used for burns, canker sores, genital herpes, and many other conditions, but there is no good scientific evidence to support these uses. There is also no good evidence to support using propolis for COVID-19.
