Sideritis is also known as ironwort, Greek mountain tea and shepherd's tea. It is a genus of flowering plants well known for their use as herbal medicine.

Since ancient times, sideritis has been considered a remedy for colds, aches, allergies, indigestion, respiratory issues and a boost for the immune system. An increasing number of research confirms that mountain tea is packed with flavonoids and antioxidants, and that it lowers blood pressure.

Sideritis is usually consumed as a tea, often with honey, cinnamon or lemon.
