Horsetail (Equisetum arvense), commonly known as buttlebrush, is a perennial plant that has been used medicinally for centuries. Indigenous to Europe, North Africa, northern Asia, and the Americas, horsetail is rich in silicic acid, flavonoids, phenolic acids, and sterols, which contribute to its health-promoting properties. The plant is known for supporting the strength and elasticity of connective tissues, making it beneficial for conditions like arthritis and rheumatism. Horsetail is also a natural source of silica, which aids in collagen production, promoting bone health, and enhancing the strength of hair, skin, and nails. As a natural diuretic, it is used to manage urinary tract infections, prostate disease, and cystitis. Additionally, horsetail possesses astringent properties, making it effective for stopping nosebleeds and treating wounds. It is commonly added to baths to relieve skin conditions like eczema and sprains, highlighting its versatility as a traditional remedy.
