Oregano, which grows widely in the temperate regions of Europe, Asia and North Africa, has been known as a medicinal plant since ancient times. Thyme used in the spice industry and in the pharmaceutical industry due to its anti-fungal and antiseptic properties because it has an aromatic smell, also contains some vitamins and minerals that humans and animals need. The use of oregano, which comes to the forefront in the feeding of small ruminants during the times when animal feeds are scarce in our country, is becoming more and more important in small head and poultry production and good agriculture and organic farming applications due to some secondary metabolites it contains.
