Against this product speaks three things: - It is based on mineral oils - this is for a skin cream ever quite wrong - There is a lack of information, how much propolis is actually added - There is a lack of reference to the origin and quality of the used propolis It would be interesting for the consumer to know whether or how much the Propolis is loaded with Varroa treatment agents. My tip: You contact the beekeepers in your neighborhood and get yourself as pure propolis. Thus a cream is quite simple stirred together - with the full control over the type and quantity of ingredients.
