Oregano (<italic>Origanum onites</italic> L.) is an important medicinal and aromatic plant. The use of sector and economic value of oregano are determined by quality in world trade.

Oregano (Origanum onites L.) is an important medicinal and aromatic plant. The use of sector and economic value of oregano are determined by quality in world trade.
