Wintergreen is an herb. Wintergreen oil is made by steam processing of warmed, water-soaked wintergreen leaves. The leaves and oil are used to make medicine.

Wintergreen is a shrub-like plant that grows up to six inches in height and bears foliage round the year. When the plant is young it bears pale or yellowish green elliptical leaves that are delicately jagged or toothed. However, the mature leaves are rubbery and lustrous. The surface of the mature leaves is dark green in color, while below they are lighter. Wintergreen bears bell-shaped white flowers during the months of July-August and these are followed by red fruits.

Wintergreen grows best in a damp, but not marshy, humus rich soil in shadow or partial shade. The herb prefers moisture and flourishes in peat (an accumulation of partially decayed vegetation matter). The species also requires a lime-free soil and grows well even on arid soils when it has been well set up and can endure drought conditions to a large extent. Wintergreen thrives fine under gentle shades of deciduous (perennial plants that shed leaves once in a year) shrubs or evergreens (plants that retain their leaves throughout the year).

While the herb is collected during the fall, wintergreen fruits or berries are harvested both during the spring as well as fall. The leaves of wintergreen herb are gathered all through the year, but summer is the best time. Leaves of the herb are dried in the shade.

Significantly, all parts of the plant are scented and one may smell the original odor of wintergreen when the leaves of the plants are crushed. All plants classified under this genus are generally dead set against honey fungus.

Wintergreen oil is applied to the skin as a “counterirritant” to relieve muscle pain. Counterirritants work by causing irritation that reduces pain and swelling in the underlying tissue. Wintergreen oil is also used to kill germs on the skin.

Wintergreen was also used to add essence to candies, cough drops as well as toothpastes. Incidentally, the practice still continues as many such products available in the market suggest the usage of wintergreen extracts even today. However, over the years, the herb has mostly been substituted by synthetic substances. Therefore, these days wintergreen is only animals like the deer and the partridge that thrive on the original evergreen herb as it serves as their staple food during the winter months.

As a medicinal herb wintergreen has numerous functions. The herb is robustly anti-inflammatory, has anti-septic properties and is comforting to the digestive system.

All over the world people use the wintergreen especially for its oil extract which contains large proportions of methyl salicylate.

This also explains why the herb is a useful medication in treating rheumatism.
