Horsetail is a plant that has been used as a herbal medicine since ancient times. The plant's stem and leaves have been used in the past to treat skin conditions such as eczema, psoriasis, and acne.
The medicinal properties of horsetail are believed to come from its high silica content. Silica helps the body produce collagen and elastin, which are essential for healthy skin.
Horsetail can be consumed in supplement form or applied topically to the skin in order to reap its skincare benefits.
