Uses
The foliage has a sweet scent and is a traditional insect repellent, used by campers to keep biting insects out of tents. It is also a traditional component of royal wedding bouquets and is used variously in perfumery and as a condiment.
In Scotland, UK, it has been traditionally used to ward off the Highland midge,[ Archived] and it is marketed as an insect repellent and as an ingredient in some soaps.[ ]

The leaves can be dried to make tea, and both the nutlets and leaves can be used (either chopped or dried) to make a seasoning.
In northwestern Europe (Germany, Belgium and the Netherlands), it was much used in a mixture called gruit as a flavouring for beer from the Middle Ages to the 16th century, but it fell into disuse after hops supplanted gruit herbs for political and economic reasons.[Justyna, Wubs-Mrozewicz (2005). Hopped Beer as an innovation; The Bergen Beer Market around 1200-1600 in the European Context. H. Brand (ed.) Trade, Diplomacy and Cultural Exchange, (2005) pp. 152-168] In modern times, some brewers have revisited this historic technique and in Denmark and Sweden the plant is commonly used to prepare home-flavoured schnaps.[Patrick E. McGovern, Gretchen R. Hall, Armen Mirzoian, " A biomolecular archaeological approach to Nordic grog" in Danish Journal of Archaeology (2013) pp. 112-131, see p. 124]
In some Native Canadian cultures in Eastern Canada, the plant has been used as a traditional remedy for stomach aches, fever, bronchial ailments, and liver problems.
In 2007 there were plans to increase production of the plant in Scotland for use as an essential oil for treating sensitive skin and acne. The plant has been listed as an abortifacient and therefore should not be consumed by people who are, or might be, pregnant.
In culture
Queen Victoria was given a sprig of bog-myrtle which she planted on the Isle of Wight. Her daughter used some of the plant that grew in her wedding bouquet, starting a royal tradition.
