Horehound is a medicinal plant that has been known for centuries. Its botanical name is Marrubium vulgare L, but it is also known as wall horehound, white horehound or white dorant. Originally, it comes from the Mediterranean region. Today, however, it is also native to our Central European latitudes. Horehound contains, among other things, bitter and tannic substances, resins and some waxes. It also contains small amounts of essential oils. To make horehound tea, the upper parts of the plant are cut off, tied together in bunches and hung up to dry. In 2018, it was voted medicinal plant of the year.
