1. What is oregano?

Oregano is an aromatic plant widely used as a spice and also valued for its health benefits. Oregano is a perennialherb belonging to the mint family (Lamiaceae). It grows naturally in Europe, including Lithuania, and is well known in both culinary and folk medicine.

For beginners, it is important to understand that oregano is not just a spice for pizza or sauces. It is a plant that contains active ingredients that determine its aroma, taste and positive effects on the body.

Common oregano (Origanum vulgare) is the most common type of oregano. It grows in meadows, forest edges, and hilly areas, preferring sun and light soil. The plant is characterized by small oval leaves and pink or purple flowers.

Botanically, oregano is distinguished by its high content of essential oils , which give it its characteristic aroma. It is precisely because of these properties that common oregano has become an integral part of Mediterranean cuisine.
