I’ve been using herbs, like horsetail (also known as shavegrass), for years to handle minor health issues at home. Horsetail is a staple in my herb cabinet and is my go-to for supporting hair, skin, and nail health. Recently, I’ve discovered even more benefits of this versatile herb.
Horsetail (Equisetum arvense) is a medicinal plant that dates back to ancient Greek and Roman times, but it actually existed long before, as far back as prehistoric times. Back then, horsetail was tree-sized, but today’s version grows to about four feet tall. It’s considered the richest source of silica in the plant world, which is why it was historically used to polish metal.
The above-ground part of the plant is used in herbal medicine and has been traditionally applied to support health in many areas. Although there’s limited scientific research on horsetail, the existing studies are promising and suggest more exploration is needed.
Horsetail is not only popular in traditional medicine but is also gaining scientific validation. It is packed with nutrients, including Kynurenic acid, which helps reduce inflammation and pain, and silica, which supports collagen production. Additionally, it contains chlorophyll, which may fight cancer by preventing harmful effects related to iron metabolism. Moreover, horsetail’s antioxidant properties are believed to help inhibit cancer cell growth.
One of the standout benefits of horsetail is its high silica content, which is essential for bone and teeth health. A 1999 study found that post-menopausal women with osteoporosis regained significant bone density after a year of horsetail supplementation.
Traditional herbalists have used horsetail for treating wounds like boils and carbuncles because of its antimicrobial and anti-inflammatory properties. A study in 2006 demonstrated horsetail essential oil’s effectiveness against various bacteria and fungi, such as Staph and Salmonella.
Horsetail is also used as a diuretic and for bladder issues. A 2014 study showed it was as effective as traditional diuretic medicine (hydrochlorothiazide) without the side effects often associated with these drugs, such as liver or kidney function changes or electrolyte imbalance. In fact, horsetail is a good source of electrolytes, which may explain why it doesn’t cause these issues.
For hair, skin, and nails, horsetail is highly beneficial due to its high silica content, which enhances collagen production crucial for healthy hair, skin, and nails. Research supports this with findings that hair containing more silica sheds less and appears more lustrous. It may even help regrow hair after hair loss, with a 2012 study showing significant hair growth after using horsetail supplements for 90 to 180 days.
A study in the Journal of Plastic Dermatology found that using horsetail topically on nails reduced splitting and fragility. Additionally, horsetail ointment was found to assist in healing episiotomy wounds and lessen pain, according to a 2015 study.
I tend to use horsetail in skin and hair preparations because of its high silica content. While I avoid using it internally when pregnant or nursing, I still find it beneficial for external applications if needed.
Generally, short-term use of horsetail is considered safe, although it’s important to consult a healthcare professional before starting any new supplement. It can be purchased online, made into tea, or taken in capsule form. Growing your own horsetail is also an option, though it may spread quickly, so starting it in a container is advisable.
