Patient Education

Oregano


What is it? Oregano (Origanum vulgare) is an herb used to flavor foods. It is considered safe in common food amounts, but has little evidence of health benefits.

Oregano has olive-green leaves and purple flowers. It is closely related to other herbs, including mint, thyme, marjoram, and basil. Oregano contains chemicals that might help reduce cough. Oregano also might help with digestion and with fighting against some bacteria and viruses.

People use oregano for wound healing, parasite infections, and many other conditions, but there is no good scientific evidence to support these uses.
