Borojo fruit scientifically known as Alibertia patinoi is a small dioecious rainforest tree of genus Alibertia and Rubiaceae family. The plant is native to northwest area of Colombia in the Chocó Department and in the Esmeraldas Province of Ecuador, in areas of high humidity and an average temperature, both in the wild and on local farms. Borojó is an Emberá word meaning: boro = head, jo = fruit – head-shaped fruit, or round, globulous fruit. The species has also been reported from Panamá and Costa Rica. The Borojo tree needs a lot of shade, and usually grows in the shade of other trees. Few of the popular common names of the plant are Burijo and burojó. Fruits are traditionally used in jam, desserts, ice cream, and candies, among other things — not the least of which is the famed Jugo del Amor (Juice of Love). Fruits contain phosphorus and essential amino acids, as well as other important vitamins and minerals including vitamin C, calcium, and iron. Promoters also claim Borojo may help maintain normal levels of blood sugar, blood pressure, and cholesterol, as well as normal estrogen production in women.
Plant Description
Borojo fruit is a mid-sized, tropical evergreen shrub that grows about 3 to 5m tall. The plant needs high humidity and temperature (an average of at least 25 °C) to thrive, though it can tolerate brief frosts as well as floods. The plant has grey-brown bark and sometimes has two or three smaller trunks as well as one main one.
Flower
Borojo is dioecious (separate male and female plants). Male Borojo plants have clusters of fragrant white flowers. Females have a single white flower at the tips of branches. Only the female plants produce fruits. Masculine flowers in chapters, short calyx, prismatic or conic, generally actinomorphous, sessile, pentamerous and occasionally tetramerous without an ovary or, if it exists, it is rudimentary or non-functional. Feminine flowers are lonely and terminal with two pairs of bracteal stipules and six longer stigmas; inferior ovary, with umbilical calyx at the base, six cavities and many ovules, corolla with six to nine petals, lineal stamen, empty or sterile.
Fruit
The fruit is large about 7 to 12 centimeters in diameter, with a round shape, green in color at the beginning and light brown at maturity and average weight of 740-1000 grams. The pulp represents 88% of the total weight and 12% seeds and shell. The pulp is brown, acid, and very dense (consisting mostly of fructose and glucose). The pulp constituted by mesocarp and the endocarp, with no apparent separation from the shell, weight between 740 and 1 kg. Each fruit has 90 to 640 seeds, and it is considered ripe when it falls to the ground. Borojo has high levels of protein, phosphorus, ascorbic acid, calcium and iron. Borojo is used in the preparation of jam, wine, desserts and traditional medicines with supposed aphrodisiac effects. It is also used by the local communities against hypertension, bronchial diseases and malnutrition.
The fruit cannot be harvested green. At maturity the fruit turns brown, and falls on the ground. Only then the fruit can be harvested and only then, the fruit has all the legendary properties it is known for. The pulp has a relative humidity higher than 60%, indicating that it has high water content in its composition. In dry weight most of the borojo are carbohydrates, dietary fiber, protein, calcium, phosphorus and iron. In traditional medicine the juice of this fruit is used to treat sexual impotence, bronchial affections, Hypertension, cancer, infections and chronic fatigue.
