(Origanum vulgare)

This herb is often used in the kitchen, however, it’s also a potent essential oil which has many medicinal and cleaning uses. The plant and essential oil have both antimicrobial and antioxidant actions and were used in traditional/herbal medicine for years to treat issues. We get oregano essential oil by steam distilling the leaves or shoots of the oregano plant.

Aromatic Profile
Oregano essential oil has a warm, sharp and herbaceous aroma. It is more intense than the herb’s scent because of the stronger concentration of the oil. Blends well with bergamot, pine, oakmoss, citronella, basil, rosemary, cedarwood and lavender.

Due to its antimicrobial and antifungal properties, this oil mixed with water, vinegar and other antibacterial essential oils makes a great all-purpose cleanser and it’s strong herby aroma will also help to freshen the air. You can use this oil in a diffuser to help assist with coughs, asthma and respiratory infections.
