Patient Education

Horsetail


What is it? Horsetail refers to various plant species of the Equisetum genus. It may help reduce fluid retention, but might cause vitamin B1 deficiency when used long-term.

The chemicals in horsetail might have antioxidant and anti-inflammatory effects. They might also work like "water pills" (diuretics) and increase urination.

People use horsetail for fluid retention, urinary tract infections (UTIs), osteoporosis, loss of bladder control, and many other conditions, but there is no good scientific evidence to support these uses.
