Yucca filamentosa L., and Yucca glauca:
A sweet herb used for gout and
beneficial in treatment of urethritis and prostatitis. A blood
purifier . Reduces inflammation of the joints, helpful for arthritis, neuritis, neuralgia, and rheumatism.
Cut up in water to make a natural lather as a soap substitute, can
add to shampoos, or can use alone to wash hair. Said to control dandruff and relieve baldness. (1 cup chopped root soaked in 2 cups of water).
The roots can be chopped and soaked in water to extract a soapy substance
the western Native Americans used for washing. The shoots of the plant
can be double-boiled to produce a winelike liquid which was used by
the Native Americans as a stimulating tonic.
Also, they poulticed root on inflammations, sores, skin diseases, used it
to stop bleeding; in steam bath for sprains and broken limbs. Leaf
juice used to make poison arrows. Pounded roots were put in water
to stupefy corralled fish so they would float to the surface for easy
harvest.
Some clinics in the Sonoran desert region of Arizona routinely prescribe
yucca against arthritis, with impressive results. (These findings
have been disputed)

Occasionally there are some purgative side effects that may be accompanied
by intestinal cramping. This can be prevented by adding as an antidote
some ginger and prickly ash bark, which also will aid its antiarthritic
properties. Long term use is said to slow absorption of fat-soluble
vitamins, but these findings require further study.
Root compound (saponins) are toxic to lower life forms.
