Willow, of the family Salicaceae and genus Salix, has many trees and shrubs; 300 species vary from less than 1 in. in height to trees of 100 ft. or more, depending on local and climatic conditions. In North America we can claim over 100 of the species variety. Largest of the Willows of eastern North America is the Black willow S. Nigra. It has dark-brown, ridged bark, reddish to orange twigs, and long, narrow leaves that are taper-pointed. The flowers are in elongated clusters, aments or catkins, of two different types; however, in rare instances, the flowers are bisexual. The “precocious” catkins are ornamental, and among flowering plants Willow is ancient, fossils extending back to the Cretaceous.
Branches
Shoots and larger branches are pointed upright. The smaller branches are drooping and sagging. Branches are brittle and can break easily. If placed in moist soils, these branches will take root. It occurs along the concave or the inner meander of streams and rivers where broken branches may drift to their new location.
Twigs
Twigs are slim, flexible and rounded. They are brittle at their base. Each twig is red-brown, light orange, olive, orange-green, golden yellow, yellow green and is hairless. The young twigs are slightly hairy. Older twigs are darker and grayer. Twigs are alternate U-shaped leaf scars. Each leaf scar has 3 bundle scars and longitudinal ridge running downward.
Buds
There are no terminal buds. Lateral buds are about 1/8 inch long, conical, narrow, shiny, smooth, brown to red or yellow-brown and pointed. They are appressed and flat upon the side next to the twig and are rounded upon the opposite side. Each bud has only one cap like scale.
Leaves
Leaves are simple, alternate and deciduous. Each leaf is lanceolate and linear. They are rounded or wedged at bases and long tapered tips which are curved to one side and finely serrated margins with 15 to 30 teeth per inch. They are 1 to 8 inches long and about 1/8 to ¾ inches wide. They are hairless, shiny dark green above and lighter green below. Leaf petioles are short, glandless, hairy and short. Leaves are fast growing shoots having stipules which often encircle the shoot. Stipules are large, green, paired, ovoid or semi-cordated, persistent and dentate.

Health Benefits of Black Willow
- Treatment for acne
Salicylic acid is an ingredient used for treating acne. It is a natural exfoliator and eliminates dead cells and prevents pores from closing and causing pimples. The daily use of salicylic acid keeps skin free from excess dead cells for preventing acne breakouts. Willow bark has acids which has similar to cyclic acid and helps to exfoliate the skin and makes it blemish free.

Uses
Willow is very similar in action to quinine; the active principle is Salicin and is believed to be far more valuable for ague and low grades of fever. These salicylic acids are found in a number of herbal remedies used throughout the world, some dating as far back as the Stone Age. We cannot trace the discovery of how the Willow first became known to the American Indians, we can only tell you that when they were in need of a fever-reducing agent Willow bark tea was given.
In 1763 the Rev. Edward Stone applied an old-fashioned theory. Three things were obvious—low, marshy regions; rheumatism; Willow trees. He tried a decoction of Willow bark on sufferers of rheumatic complaints and thus rediscovered the effectiveness of salicylic acid (Salix is Latin for Willow). It wasn’t long before experimentally inclined chemists began synthesizing this substance from common coal tar and petroleum derivatives, according to a standard recipe given in many elementary chemistry text books. Today it is known as common aspirin. The amount swallowed to date in the U.S.A. is approaching an annual 35 million lb., or five tablets a week for every man, woman and child. The contents of modern aspirin is from man’s integrity rather than from God’s goodness. Is highly recommended and largely used in the treatment of spermatorrhoea, nocturnal emissions, etc. Also relieves ovarian pain.
