Royal jelly is a strange substance that makes a queen bee a queen bee. This proteinbased substance is secreted from a gland at the head of the worker bee. Royal jelly is
food for the queen bee, and its ingredients are full of rich nutrients, such as protein,
vitamins and minerals. While worker bees only live for about one month, a queen bee
has a life time of three to four years, several tens of times longer. Because of this
extremely long lifetime of a queen bee, despite that it has the same genes as worker
bees, royal jelly as its food has been considered a medicine for perennial youth and
long life.
