Yucca: Can it relieve arthritis symptoms?

Yucca supplements have long been touted as a possible treatment for osteoarthritis. However, except for one small preliminary study reported in 1975, there have been no published clinical trials evaluating its effectiveness in treating osteoarthritis. Yucca is a group of evergreen shrubs and trees that grows in arid regions of North America. Although scientific studies have validated many alternative and complementary therapies for osteoarthritis, yucca is not one of them.
