Pollen

Humans use pollen as a food supplement because it is believed to boost the immune system, build strength, stamina and vitality.
It is also used in creams to rejuvenate and sooth skin.
Pollen is used to rear insects and feed birds.
It can also be used as feedback to colonies during pollen- deficient nectar flows or to queen cell builders.
