Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Edible Uses:

The softer tissues of the bark, stems and wood are used to extract the white or brownish sap which has been shown to contain 2.73% caffeine. The native people in adjacent Colombia regularly used this product as a stimulating breakfast beverage[434 , 521 ]. The stem is cut into pieces 30 - 100cm long, and the epidermis, cortex, and phloem are rasped. The scrapings thus obtained are squeezed to express the caffein-bearing sap into cold water (hot or warm water is never used with yoco), the rasped tissues being then discarded. The liquid, of a cloudy milky-white or light chocolate-brown colour, is drunk cold. The beverage, which is taken early every morning, allays hunger and supplies muscular stimulation[476 ]. Lianas of Paullinia Yoco, which have a stout stem at least 8cm in diameter at the base, are utilized. Usually several trees must be felled before the liana falls to the ground. Starting at the root, the stem is then cut into pieces which may vary from 30 - 100cm in length. These pieces are stored in cool corners of Indian houses and can retain their stimulating properties for a month or even longer[928 ].

A beverage made from the stem (see edible uses), is taken medicinally as a febrifuge and as a curative for a bilious disease[476 , 928 ]. In addition to its use as a stimulant, yoco is employed, in larger dosages, as an anti-malarial febrifuge and as a medicine in the treatment of a bilious disease which is frequent in the Putumayo[928 ].
