Extra Information Leaves of this plant used to be added to the beer-brewing-process in North-Germany until early 1900. It gave an extra 'arousing' effect. This practice became illegal around 1910. Due to its strong fragrance, it has also formerly been used as a natural anti-moth (for Clothing Moth) in Scandinavia. (Hence the name "Mottenkraut" in German) The genus Ledum became only recently part of the Rhododendron genus. So there are lots of 'old names' and 'wrong names'. For more information see: Ledum taxonomy, or the UBC-forum.
