Oregano, and its close cousin Marjoram, share many of the same attributes. Oregano has the stronger flavor and slightly stronger healing benefits. It is antispasmodic, calming, a stomach tonic for indigestion and colic, and an expectorant. Wild oregano appears to be even stronger and is available as Oreganol. Oregano and marjoram look alike but there is a difference. Oregano has a sharper taste than marjoram, marjoram tastes sweeter and milder than oregano. In fact, marjoram is usually referred to as sweet marjoram. These are easy to grow perennial herbs so I hope you can make space in your garden for them. Cooking? Oregano is used extensively in Italian and Mexican dishes.
