Yucca Schidigera



The Mojave yucca (Yucca schidigera), also known as the Spanish Dagger, is a flowering plant in the family Agavaceae. It is native to the Mojave Desert and Sonoran Desert of southeastern California, Baja California, southern Nevada and western Arizona.

Some reports claim that Native Americans washed their hair with yucca to fight dandruff and hair loss. Among the other maladies this yucca has been used to treat are headaches, bleeding, gonorrhea, arthritis and rheumatism.

Yucca schidigera is a traditionnal medicinal plant native to Mexico : it was used by native americans as an help in the treatment of arthitis and inflammation. Yucca phenolics may interact with inflammatory mediators and are also are antioxidants and free-radical scavengers.


Powder obtained from Yucca.

Natural Concentrate, Gum arabic.

Botanical name : Yucca schidigera Roezl ex Ortgies

Plant part used : Root

The influence of a phenolic-rich fraction from yucca and of its main phenolic constituents on key enzymes of arachidonate metabolism was investigated:

1) The fraction and the pure phenolics were shown to inhibit COX-1, COX-2, and LTB 4 formation by 5-LOX in vitro to different extents.

2) The inhibitory activity on key enzymes of arachidonate metabolism observed in this study might contribute to the explanation of the anti-inflammatory and antiplatelet effects observed for Y. Schidigera and its phenolic constituents.

In vitro studies have reported :

1) Anti-inflammatory effect

2) Anti-oxidant effect

3) Anti-arthritic effect

Yucca schildigera is rich in two large families of molecules:

Saponins: glucocorticoid-like effects may be involved in the anti-inflammatory effects.

Polyphenols: inhibition of enzymes of the inflammatory cascade of the arachidonic acid COX-1, COX-2 and 5-LOX, and therefore leads to the drop in the production of the inflammation mediators i.e. prostaglandins PGE2  and leukotrienes LTB4.

Yucca powder would be an inhibitor with an anti-inflammatory double action. The polyphenols show good antioxidant properties in vitro (capture of free radicals, inhibition of some peroxidation reactions, action on the ROS).
