Yucca is an all-natural steroidal supplement. Its therapeutic components include saponins which are anti-inflammatory agents that act through specific receptor proteins in the cytoplasm of responsive cells. Yucca reduces pain with minimal gastric side effects. It is used for arthritis and other joint problems, soft tissue swelling, and certain digestive problems. Yucca also is said to promote circulation through damaged tissue, reducing waste build-up while also helping in the removal of waste from the liver and kidneys. The increased circulation also provides more tissue-repairing nutrients.
