Description

Horsetail is a perennial plant that produces fertile and infertile shoots that are deciduous. Each fertile shoot is unbranched and about 4–8 feet tall. It has a jointed central stalk that is light brown, terete, glabrous, and about 6 mm across in diameter; it also has 8–12 shallow longitudinal ridges that are separated by shallow grooves.

At the conjunctions of its joints, there are sheaths with black triangular teeth along their upper rims. This stalk terminates in a spore-bearing cone, the cone is lanceolate-oblong in shape and rounded at its apex. The surface of the cone is mostly light brown, but it is covered with spore-bearing tubercles that have black, brown, and white markings.

The fertile shoots develop during mid-spring, but they soon wither away after the cones have released their spores to the wind. The infertile shoots have a very different appearance. They develop during mid-to-late spring and persist until the fall. The infertile shoots have whorls of ascending branchlets along at least the upper two-thirds of their stems. The stems and branches of these shoots are slender, glabrous, and green.

Chemical CompositionThe whole plant mainly contains saponins, flavonoids, triterpenoids and steroids, alkaloids and a large amount of silicic acid, β - sitosterol, vitamin C, carotene and so on.
