Raw propolis inside the hive (photo www.propolis.fr)
Propolis has numerous properties:
- antioxidant and anti-rancident
- protective jar
- intestinal peristalsis stimulating
Propolis collected by means of a scraper contains large percentages of wax, bee fragments and other foreign bodies and to put it on sale it is necessary to carry out a thorough cleaning.
Otherwise there is another method of collection: using a frame of the size of the attic, to be replaced by the latter, with a mesh of about 2 mm spread over it. The bees, being devoid of the upper part of the hermetic hive, will immediately proceed to propolis the frame which will eventually be withdrawn covered with propolis. A sort of stainless steel diaphragm has also recently been put on the market for the same purpose.
