piculture, or keeping bees to use their products, is a very old practice. Originally, people only hunted beehives. Not only did they eat the honey from the beehives; they also mixed it with water and left it to ferment so they could make alcoholic drinks. Today the production of honey has been perfected in such a way that other products, such as pollen, royal jelly, and propolis, or bee glue, are also obtained from the hive.
