Customs and Traditions –
Davilla rugosa, known by the common names of bejuco colorado or bejuco guará, is a herb that has historically been used in Brazilian folk medicine. One possible use of the herb is as an anxiolytic agent. For example, in one study, researchers made extracts using the stems of the plant and fed it to rats before exposing them to experimental stress. A significant anxiolytic effect was observed with the extract but it also had a stimulating effect on rats. This may suggest that the anxiolytic effect is related to the stimulating effects of the herb. It has been shown that the main active ingredients contained in the stem of the plant are flavonoids, saponins and mucilages.
The leaves of the plant have been shown to contain the flavonoids quercetin, kaempferol and myricetin. Other components identified in the plant include alkaloids and tannins. Instead, caffeine was isolated from the seed of the plant. The stimulating effect of the plant may therefore be due to caffeine, although it is not clear whether caffeine is represented in the stems, as used in this study.

Preparation Method –
The leaves of this plant are used, especially among the peoples of South America.
