Weeds & Seeds Swap

Horsetail goes by the botanical name Equisetum arvense. Though native to Europe, we have it all over in the area where I live, in Northern NJ, perhaps because we are in a lake community and the herb loves moist soil. When you drive out of our community, it grows heavily along the roadway beside another lake close to us. The Latin name means “horse bristle”. Fossil records show that this plant is very primitive. It also shows that the plant used to grow as tall as sixty feet! Now it grows to about 2 feet.

Historical Use:

Meskwaki Indians fed Horsetail to their horses to improve the gloss of the hair, the main & tail. It was also used to scrub, clean & polish cooking utensils. The Greek physician, Diosorides, suggested using it as an astringent. In Switzerland, a tincture was used for cystitis and tuberculosis. American Indians and the early American settlers used it as a diuretic for kidney disorders. Folk medicine indicates use to help with excess menstruation and bleeding. The properties that probably gave the herb all these useful benefits include the fact that the herb is astringent, antiseptic, ani-hemorrhagic, diaphoretic, emmengogue, homeostatic, tonic and vulnerary. Today, it is suggested as one of a number of herbs helpful during cold and flu season to increase resistance to infection.

Scientific Info:

Horsetail can be used as an astringent both internally and externally to treat skin abrasions, diarrhea and indigestion (Spoerke, “Herbal Medications”). Silica is one of the main nutrients found in horsetail, an extremely common element in the earth. It is also found in the connective tissue throughout the body, aiding in the building and repair of connective tissue. It helps to increase collagen, and aids the body is using calcium to build bones. A UCLA study found that silicon supplements significantly increased bone calcium content as opposed to non-supplementation (Faelton, “Complete Book of Minerals and Health”). (Note: This is why a calcium supplement that I use, Skeletal Strength, contains certain herbs, because not only does vitamin D, Magnesium, etc. help with calcium absorption, but also the properties in the herbs.)

Some research seems to indicate that because Horsetail is high in Silica, which reduces blood cholesterol and helps to prevent aging and degenerative disorders like heart disease, for example. Silica is also beneficial to the skin & eyes. The flavanoids in Horsetail strengthen the capillaries, it’s phytosterols, or plant steriods, help with inflammation. Some use it for inflammation in the kidneys, bladder, and prostate. This herb is also a great source of vitamins, minerals and trace elements. It has moderately high levels of vitamin E and pantothenic acid (B5). The minerals/trace minerals include calcium, potassium, copper, manganese, selenium, iron, phosphorus, sodium, cobalt and iodine, contributing to strong connective tissue, hair, skin and nails.

PABA, a building block to folic acid and antioxidant that protects the skin from sunburn, is also found in horsetail.
