Ethnobotanical Uses


"Best-tasting parts: Flower buds, flowers, and young fruits. Raw or cooked. Buds and flowers work well in soups, salads, omelets, kebabs, fritters, or stir-fries. Young fruits can be sliced and fried, baked, stuffed, barbecued, or pickled. Dehydrate to preserve. Seeds may be roasted and ground into flour. Some people report a disagreeable aftertaste and/or laxative effect with this plant." (Seebeck 105)

"The flowers have been eaten raw in salads, cooked in soups, or deep-fried like squash blossoms. It is recommended that their bitter, green centers be removed. The young seed pods were roasted in ashes and eaten, and the ripe fruits were peeled, seeded and baked. They have been used like apples in pies and jams. The leaves are also said to have been boiled with salt and eaten, but they are extremely fibrous." (Kershaw 107)

"Tea made from the roots was given to women in prolonged labor. It was thought to clean the sticky covering from an over-sized baby and speed delivery. Similarly, a cupful of yucca suds sweetened with sugar was given to speed delivery of the afterbirth. Yucca fruit has been reported to induce vomiting, but most sources say it is edible." (Kershaw 107)

"Recent clinical studies have shown it to be of some use in the treatment of joint inflammations but the function is not understood. One-fourth ounce of the inner root should be boiled in a pint of water for fifteen minutes and drunk in three or four doses during the day. Arthritis being such an idiosyncratic disorder, no single treatment will help more than a percentage of people, but if Yucca tea is effective, it can relieve pain for several days afterwards. If a strong laxative effect persists, especially if accompanied by intestinal cramping, decrease the amount next time. ---The tea has some value for urethra or prostate inflammations." (Moore 169-70)(Moore 169-70)

"The fibrous leaves were split and used as all-purpose ties, for hanging and drying household items and for weaving loose baskets. Some tribes pounded the leaves in water to release the fibers and then twisted or plaited them to make cord, rope and nets. Narrow slips of leaves were fringed and used as paintbrushes. ---The Navajo pounded the roots with rocks to remove bark and soften the roots and then vigorously stirred the softened mass of fibers in warm water to whip up suds. This soapy mixture was used to wash wool, clothing, hair and the body. It was also said to reduce dandruff and baldness. The Ramah Navaho used the soapy mixture for ceremonial purification baths before weddings and the naming of infants and after burials. The juice of the leaves. boiled alone was used as a red dye." (Kershaw 107)

"The use of yucca fiber for matting and in basketry was and is widespread. Cloth once made from yucca cordage sometimes incorporated fur or feathers in the weave. One of the early excavations of the Frijoles ruins at Bandelier, for example, turned up a delicate blanket composed of rabbit skins combined with yucca fiber. ---Yucca root shampoo is know to give black hair a shiny look prized by ceremonial dancers."
