Horsetail Herb: Can It Help with Kidney Stones, Gravel, and Urinary Tract Health?

Horsetail (Equisetum arvense) is a medicinal plant that has been used in traditional herbal medicine for centuries. It is often promoted as a natural remedy for kidney stones, urinary “gravel,” and urinary tract infections (UTIs). While horsetail possesses compounds that may support urinary health, scientific evidence is mixed, and it should not be viewed as a substitute for professional medical treatment.

What Is Horsetail?

Horsetail is a perennial plant rich in naturally occurring compounds, including:

• Silica, which contributes to connective tissue health.
• Flavonoids, known for their antioxidant properties.
• Phenolic compounds, which may help combat oxidative stress.
• Potassium and other minerals found in small amounts.

Traditionally, horsetail has been used as a mild diuretic to increase urine production.

Can Horsetail Help with Kidney Stones?

Some herbal medicine practitioners believe that horsetail’s diuretic effect may help increase urine flow, which could support the body’s natural elimination of very small kidney stones or mineral deposits.

However, there is currently no strong clinical evidence that horsetail can dissolve kidney stones or prevent their formation. Treatment depends on the stone’s size and composition, and larger stones often require medical intervention.

What About Urinary “Gravel”?

The term urinary gravel generally refers to tiny mineral crystals that can accumulate in the urinary tract. Staying well hydrated is one of the most effective ways to help reduce crystal formation.

Although horsetail may increase urine output, there is no reliable scientific evidence proving it dissolves urinary gravel. Individuals experiencing persistent pain, blood in the urine, or difficulty urinating should seek prompt medical evaluation.

Can Horsetail Treat Urinary Tract Infections?

Laboratory studies suggest that some compounds in horsetail have antimicrobial and anti-inflammatory properties. However, there is insufficient clinical evidence to recommend horsetail as a treatment for urinary tract infections.

Most bacterial UTIs require proper diagnosis and, when appropriate, prescription antibiotics. Delaying treatment may allow the infection to spread to the kidneys, leading to more serious complications.
