XYSMALOBIUM UNDULATUM EFFECTS
Uzara root powder has a relaxing effect, described as soothing rather than sleep-inducing. There are no known side effects.
Uzara is not traditionally considered part of the African Ubulawu dream herbs, however, as it was such a widely used plant by the Xhosa, it may have been an ingredient in the dream herb mix. It may have been used to prevent side effects from occurring or possibly to help relax and prepare for the dream journey.
