Description
Bayberry is an evergreen shrub or small tree growing to about thirty feet, producing narrow, glossy, aromatic leaves, small, yellow flowers in catkins and gray, waxy berries that contain numerous blacks seeds that have a crust of usable greenish-white wax. This wax helps keep the seeds suitable for germination for up to three years. Bayberry is found in the eastern and southern regions of Canada and the US, especially around Lake Erie, and as far west as Texas. The bark is collected in autumn or spring.
Sweet Gale is a deciduous shrub that grows to about ten or fifteen feet. Both the branches and the leaves have tiny, fragrant glands that produce an aroma when crushed. Sweet Gale is indigenous to the higher latitudes of the northern hemisphere.
History
European settlers in North America believed that bayberry plants had many medicinal benefits. A 1737 account stated that it could “expel wind and ease all manner of pains proceeding from cold, therefore are good in colic, palsies, convulsions, epilepsies, and many other disorders.”
The root bark was listed in the US National Formulary from 1916 to 1936.
Its nicknames came as a result of its wax being used to make candles or in place of tallow.
The Mohegans used the tea to treat kidney disorders. Other tribes used bayberry to treat influenza, scurvy, stomach cramps, and gynecological problems.
