Background
- Yucca is the common name for the more than 40 species of perennials in the Yucca genus. The plants are well known for their tough, sword-like leaves and a large spike of whitish flowers. They are native to the hot and dry parts of North America, Central America, and the West Indies, although they are popular landscaping plants and can be found worldwide.
- There is insufficient evidence in humans to support the use of yucca for any indication. One human study indicates that a blend of Yucca schidigera and Quillaja saponaria extracts may reduce cholesterol levels in hypercholesterolemic patients. Preliminary studies also indicate that yucca may have antioxidant, antifungal, and anti-inflammatory properties.
