A common way to use oregano is by steeping a tea. The tea can be made with fresh or dried oregano. About 1 to 2 teaspoons (which is 5 to 10 grams) should be steeped in a cup of hot water for 5 minutes. The recommended dosage of this tea is up to three times daily.
Moreover, oregano oil can be applied topically for treatment of microbial infections, such as athlete’s foot or other fungal infections. The oil needs to be diluted by 50% or more prior to application and it can be applied twice daily.
