Oregano is an aromatic perennial herb that can grow to about two feet in height. It is native to the Mediterranean region but is cultivated worldwide. In addition to European oregano, there are several types of related species, including Greek/Turkish oregano (Origanum onites) and Mexican oregano (Lippia graveolens, Lippa palmeri). These should not be considered substitutes for true oregano, though they may have similar properties. The leaves as well as the volatile oil of these various species are used medicinally, but must be carefully distinguished as they are quite different.1

While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

Traditional Use (May Not Be Supported by Scientific Studies)
The name Oreganum is the contraction of two Greek words, oros meaning mountain and ganos meaning joy. Together the words suggest the beauty that oregano lends to the fields and hilltops on which it grows.2 Oregano was used extensively by the Greeks for conditions ranging from convulsions to heart failure. Nineteenth-century American Eclectic physicians (doctors who recommended herbal medicines) employed oregano as both a general tonic and to promote menstruation.3
