In addition, it is used against other skin conditions, such as scabies, pimples, pimples, to remove itching. It also deals with respiratory diseases such as cough, asthma and bronchitis.

Anthophiles (Anthophila, gr. 'That love flowers'), commonly known as bees, are a clade of hymenopteran insects, with no location in the taxonomic category, within the Apoidea superfamily. It is a monophyletic lineage with more than 20 000 known species. The bees, like the ants, evolved from wasps. The ancestors of the bees were members of the Crabronidae family and were insect predators. It is possible that the first bees have fed on the pollen that covered some of their prey and that, gradually, they have begun to feed their young with pollen instead of insects.
