Bog Myrtle – An Ancient Beer Brewing Flavouring And A Modern Insect Repellant

By David Hugonin

BOTANICAL NAME Myrica Gale

Mog Myrtle sometimes known as Sweet Gale is the badge of the Campbells and is a deciduous, bushy shrub, growing to 4 feet high. The wood and leaves are fragrant when bruised. The leaves, not unlike a willow or myrtle, are oblanceolate, tapering entire at the base, toothed and broadest at the apex, the upper side dark glossy green, the underside paler and slightly downy, under which are a few shining glands. The male plant produces flowers in May and June in crowded, stalkless catkins. The fruit catkins are about the same size, but thicker, are closely-set, resinous nutlets, the flowers being borne on the bare wood of one year’s growth. The sexes are on different plants.

Bog Myrtle is most commonly used as an alternative to the ever popular citronella as it is reputed to repel insects but bruised leaves or a little oil poured on a wood block can be used in linen cupboards very effectively.

A well know High Street chemist is planning to increase production of the plant in Scotland for use as an essential oil for treating sensitive skin and acne it is rumoured and it is also used by Totally Herby of Scotland as an insect repellent. Diluted it is finding some use in the Equine market.

The leaves are often dried to perfume linen, etc., their odour being very fragrant, but the taste bitter and astringent. It is extremely good to allay thirst. The catkins, or cones, boiled in water, give a scum beeswax, which is utilized to make candles. The bark is used to tan calfskins; if gathered in autumn, it will dye wool a good yellow colour and is used for this purpose both in Sweden and Wales. The Swedes use it frequently in strong decoction to kill insects, vermin and to cure the itch. It is undergoing a small revival in the UK now. The dried berries are put into broth and used as spice. In China, the leaves are infused like tea, and used as a stomachic and cordial.

The foliage has a sweet resinous scent, and is a traditional insect repellant, used by campers to keep biting insects out of tents. It is also a traditional ingredient of Royal Wedding bouquets, and is used variously in perfumery and as a condiment.

HISTORY:

In northwestern Europe (Germany, Belgium and Great Britain), it was a 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 had become widely available. Danish brewery Thisted Bryghus produces Porse Guld, a strong beer flavoured with the plant.

More recently the branches have been used as a substitute for hops in Yorkshire and put into a beer called there ‘Gale Beer.’
