Horse Tail

Horsetail is a plant, also known as Equisetum arvense. It grows in moist soil across North America, Europe, and Asia. The plant's stem and leaves are typically dried and used.

Horsetail is most often used in powdered drinks and teas. It is sometimes added to other beverages. It is often used for its perceived herbal properties.

In the U.S., horsetail is generally recognized as safe (GRAS) for use as a food ingredient. The FDA has not set specific regulations for its use in food. Some studies suggest horsetail may have diuretic properties. However, scientific evidence for its health effects is limited and mixed. It is not evaluated by EFSA or JECFA.
