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: Fruit  Oil  Seed
Edible Uses: Oil

The fruit contains a number of large seeds surrounded by a very aromatic, succulent pulp with a slightly acidic flavour[335 , 416 ]. This pulp can be eaten raw and is said to be delicious[317 , 335 ]. Creamy, with an exotic flavour[318 ]. Sweetish and agreeably scented[420 ]. It is also used to make fresh juice, ice cream, jam and tarts[317 , 318 ]. The brown fruit is 12 - 25cm long and 10 - 12cm in diameter, with the pulp occupying about a third of the space within[335 ]. Seed - used as a substitute for chocolate[420 ]. The seeds have a high amount of fat and give a good cocoa butter[317 ]. The seeds of species in this genus are generally a rich source of oil (around 50%), starch (around 15%) and protein (around 15%)[636 ]. They also contain a volatile oil and the stimulating alkaloids caffeine and theobromine[636 ].

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.


The plant (part not specified, but it is almost certainly the fruit or the seed[K ]) is nutritive, stimulant and tonic[318 ]. The seeds are used in the treatment of abdominal pains[318 ]. The juiced fruit is drunk to facilitate difficult births[318 ]. Although no specific reports of medicinal use have been seen for this plant, the seed is a source of cacao powder and butter. These products have the following medicinal uses:- Cacao powder and butter, which are obtained from the seed, are nutritive[238 ]. The butter is also applied externally as an emollient[238 ]. Cacao powder is taken internally in the treatment of angina and high blood pressure[238 ]. Cacao butter is an excellent emollient, being applied to the skin to soothe and soften it[238 ]. It is used traditionally to treat chapped skin and burns, and is also rubbed into bruises[238 ]. Research has shown that it can help to counter the bacteria responsible for boils and septicaemia[254 ].

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

Other Uses An oil, known as cacao butter, which is solid at room temperature, is obtained from the seed. In addition to being used locally as a food and medicine, cacao butter is important in the cosmetics and pharmaceutical industries[636 ]. The wood is of medium texture, straight-grained, moderately heavy and with moderate natural durability[420 ]. It is very little used, but is suitable for cabinet making and internal cladding of buildings[420 ].

Special Uses

Cultivation details

Management: Standard  Regional Crop

A plant of the hot, moist, lowland tropics[636 ]. It grows best in areas where annual daytime temperatures are within the range 20 - 30°c, tolerating 16 - 40°c[636 ]. It requires a mean annual rainfall within the range 2,000 - 8,000mm, evenly distributed throughout the year[636 ]. Requires a position where shade is provided by taller trees[420 ]. Prefers a relatively rich, circumneutral soil[636 ]. Prefers a pH in the range 5 - 6.5, tolerating 4.5 - 8.5[418 ]. The plant is not drought tolerant, being unable to withstand even short dry seasons without the protection of dense shade and local humidity[636 ]. Freshly planted young trees usually grow away moderately well[420 ]. A seedless variety of this species exists[416 ].

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.

Propagation

Seed - it has a very short viability, requiring high humidity and optimum temperatures to remain viable. There is no dormancy, the seed often germinating whilst still inside the pod[636 ]. Sow the seed as soon as it is ripe, in a semi-shaded position in individual containers[420 ]. Cover with about 15mm of soil. Germination rates of fresh seed is usually high, with sprouting taking place in 20 - 40 days[420 ]. Young plants are usually ready for planting out 5 - 6 months later[420 ].
