Horsetail tea may look like a trendy herbal drink, but its story goes back thousands of years. Used in traditional medicine across Europe and Asia, horsetail (scientific name: Equisetum arvense) is considered one of the oldest plants on Earth. This fern-like plant isn’t grown for its looks — it’s valued for its powerful medicinal properties, especially for bones, skin, hair, urinary health, and detoxification.
From strengthening hair strands to supporting kidney function, horsetail tea has slowly earned attention in the world of natural wellness. However, like many herbal remedies, it comes with benefits and cautions that you should understand before making it part of your daily routine.
This guide will take you through everything you need to know about horsetail tea — what it is, its nutrients, 20 proven health benefits, possible side effects, preparation methods, usage tips, and safety precautions.
What is Horsetail Tea?
Horsetail tea is an herbal infusion made from the dried stems of the horsetail plant (Equisetum arvense). The plant gets its name from its long, thin, hollow stems that resemble a horse’s tail. Rich in minerals — especially silica — horsetail has been used historically in natural medicine to support wound healing, hair growth, bone strength, and urinary tract health.
Unlike traditional teas that come from the Camellia sinensis plant (like green or black tea), horsetail tea is a caffeine-free herbal tea. It has a mildly earthy, grassy flavor and can be consumed on its own or blended with other herbs such as mint, lemon balm, or nettle.
In ancient civilizations, horsetail was not only used as a medicine but also as a natural abrasive for cleaning pots and polishing tools because of its high silica content. Today, it is mostly consumed as a tea or taken as a supplement for its healing potential.
