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

Edible Parts: Apical bud  Fruit  Oil  Sap  Seed
Edible Uses: Oil

Fruit - raw[297 , 416 ]. Slightly sweet[416 ]. A flavour similar to apricots[301 ]. Used for making juices[418 ]. After harvesting, the fruits are stored for 3 days in sacks to ripen and allow the pulp soften slightly. They must then be eaten within 3 - 4 days before they dry and rot where bruised[324 ]. The immature endosperm gives a juice called vino de tucuma, used for a drink or in culinary preparations[418 ]. An excellent oil, used for cooking, can be obtained from the fruits[297 , 324 ]. Similar to coconut oil[301 , 418 ]. The seed contains a hard white substance from which a fine edible fat can be extracted[418 ]. The seed contains 30 - 50% oil[419 ]. The apical bud is cooked and used as a vegetable[418 ]. Eating the apical bud will lead to the death of the trunk, since it is unable to produce side branches[K ]. However, it will not kill the tree since it has several stems[K ]. A wine is made from the fermented sap of the spathe[418 ].

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.


A decoction of the root is used to treat furunculosis and syphilis[348 ]. The oil from the seed is laxative[348 ]. It is used to treat rheumatism, pain and earache. It is used in a preparation for treating furuncles and is also swabbed onto aching feet and rubbed on feverish people to assist perspiration[348 ]. The fruit can be utilized against the eye disease xerophthalmia (also called ophthalmoxerosis) of which the deficiency of vitamin A is the main reason[418 ]. The whole fruit is used to calm colicky babies[348 ]. The pulp of the fruit is used to treat coughs and as a breath freshener[348 ].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Other Uses

Oil

An oil can be obtained from the fruits[297 ]. It is used in soap making[324 , 418 ]. A fine, soft, strong and durable fibre can be obtained from the unopened leaves[297 , 454 ]. It is used for weaving and cordage[297 ]. It is said to be the strongest fibre that can be produced in Amazonia and is widely used for making hammocks, ropes, bags, clothes etc[324 , 418 , 454 ]. The fibre is resistant to rot and damage and was therefore in use on sail- ships in the earlier centuries[418 ]. The shell of the kernel is used for making handicrafts such as rings, bracelets and collars[418 ]. The wood is moderately heavy, very hard, strong and durable[297 , 419 ]. It is used locally in making houses[297 ]. The stems are used as poles for fences, corrals, and rural housing[418 ]. Its resistance to diseases and high productivity make this species an alternative for the production of biodiesel, since the operating costs of an orderly plantation is much less than that of the oil palm.

Cultivation details

Management: Standard  Regional Crop  Staple Crop: Oil

A plant of the moist tropical lowlands, where it is found at elevations up to 150 metres. It grows best in areas where annual daytime temperatures are within the range 20 - 28c, but can tolerate 18 - 30c[418 ]. It can be killed by temperatures of 2c or lower[418 ]. It prefers a mean annual rainfall in the range 1,300 - 1,800mm, but tolerates 1,000 - 3,000 mm[418 ]. Requires a sunny, sheltered position[297 ]. Seedlings require some shade, whilst larger palms thrive in full sun[418 ]. Plants do not like dry conditions at their roots[297 ]. Prefers a pH in the range 5 - 7, tolerating 4 - 8[418 ]. Plants regrow very vigorously from their roots after being cut down or after a fire. They are considered to be a serious weed species of pasture land[419 ]. Young plants have a moderate rate of growth[419 ]. Although usually spiny, occasional spineless forms exist in nature[418 ].

Carbon Farming

  • Management: Standard  Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
  • Regional Crop  These crops have been domesticated and cultivated regionally but have not been adopted elsewhere and are typically not traded globally, Examples in this broad category include perennial cottons and many nuts and staple fruits.
  • Staple Crop: Oil  (0-15 percent protein, 16+ percent oil). Some of these are consumed whole while others are exclusively pressed for oil. Annuals include canola, poppyseed, maize, cottonseed, sunflower, peanut. Perennials include high-oil fruits, seeds, and nuts, such as olive, coconut, avocado, oil palm, shea, pecan, and macadamia. Some perennial oil crops are consumed whole as fruits and nuts, while others are exclusively pressed for oil (and some are used fresh and for oil).

Propagation

The seed is enclosed in a hard endocarp which makes germination slow and erratic[297 ], and also has a short viability in storage[419 ]. It may benefit from scarification before sowing to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing. It is best to sow the seed as soon as it is ripe in a partially shaded position in a nursery seedbed or in individual containers. A high germination rate can usually be expected, with the seed sprouting within 90 - 150 days[419 ]. When the seedbed-sown seedlings are 5 - 8cm tall, pot them up into individual containers and they should be ready to plant out 6 - 9 months later[419 ].
