The baobab powder, extracted from the Baobab, the king of trees
Everyone will agree that the baobab is a special tree with its massive trunk, unique shape â€“ which according to legend is the result of God planting it upside down – and its powerful presence.
This king of trees seems to hold aeons of life-experience like a wizened old elephant matriarch or like a tall rugged mountain. It is one of natureâ€™s cathedrals, offering shelter, food and relief from sickness. It is no wonder that this gargantuan deciduous tree holds a place in our hearts and has inspired myths and superstition.
Itâ€™s the stuff of legends – living to hundreds of years old; its hollow interior having served as a chapel, water reservoir, shop and place of refuge; its fibrous bark collapsing to the ground at the end of its life cycle; and its delicate and pendulous white flowers, centred with a soft brush of bright yellow pollen, blooming for only 24 hours before falling like confetti at a wedding. There are eight species of baobab: an African, six Madagascan and one Australian species.
Baobab – The king of trees
The African baobab Andansonia digitata or Kremetartboom at itâ€™s known in Afrikaans, occurs at low altitudes in hot, dry woodland in the continentâ€™s more tropical regions, in well-drained stony soil. It has compound finger-like leaves composed in spirals of 5-7 leafl ets at the ends of single long stalks. Its greyish-brown unevenlyfolded trunk can be more than 20m in circumference although it is often not more than 15m high.
Waxy white flowers appear in spring or early summer. The buds start to open in the late afternoon, the flowers opening completely at sunset to be pollinated at night by fruit bats and several species of bushbaby. By the next afternoon they have wilted and fallen to the ground. The oval fruit has a hard woody shell and contains a powdery white pulp, rich in vitamin C and likened to cream of tartar. A drink made with the pulp has been used to treat fevers and diarrhoea and the powdered seeds are said to cure childrenâ€™s hiccups.
The seeds are dispersed by large mammals like primates and elephants. Some of the superstitions surrounding the baobab include the belief that if you pick a baobab flower, you will be devoured by a lion as the blossoms are inhabited by spirits, that the water the seeds have been soaked in will act as protection against an attack by a crocodile (although sucking and eating the seeds will attract a crocodile), an infusion of the bark will make a man strong and that a baby boy should be washed in water in which the bark has been soaked. The great tree has a patchy distribution in the northern areas of the country.
Amongst Namibiaâ€™s better- known baobabs are those that cling tenaciously to the rocky edges of Epupa Falls, the impressive Holboom in the Nyae Nyae conservancy, the Dorslandboom on the way to Khaudum Game Reserve where the Dorsland trekkers are said to have camped in the late 1800s, â€˜Tree 1063â€™ on Keibeb farm near Grootfontein and the Ombalantu baobab in Outapi.
The Ombalantu baobab is a heritage site with a long history. The hundreds-of-year old omukwa or baobab was once a place of refuge for the Ombalantu people who climbed into its centre and hid between its fibrous walls during tribal wars and cattle skirmishes. It was later used as a post-office and finally a chapel.
A lectern with a bible and several benches remain in the baobabâ€™s centre and visitors to the Ombalantu Baobab Tree Campsite are welcome to sit in the living chapel. Baobabs demand reverence by virtue of their sheer size and age. They tower into the sky, crowned by birdsâ€™ nests and a fringe of green leaves or they stand stark and imposing on the arid land. Whatever the season, the king of trees cannot be ignored.
Baobab is a deciduous tropical fruit tree ranging in height from 5 to 25 m and is distributed in belts in low-lying areas across Africa, Madagascar, India, Sri Lanka and Australia.
It belongs to the family called Bombacaceae. It is a very long-lived, fast-growing tree and has a lifespan of hundreds to thousands of years. The growth of the baobab is mainly managed and protected by local people. Baobabs are widespread throughout the hot, drier regions of tropical Africa, extending from Mozambique, the northern provinces of South Africa and Namibia to Ethiopia, Sudan and southern fringes of the Sahara. In South Africa the tree is found in the frost-free areas near Waterpoort in the Western Soutpansberg of the Limpopo Province.
Climatic and soil requirements
Baobabs occur in semiarid to subhumid tropical zones.
They grow on many different soils including sandy loam but develop best on calcareous substrates and on deep, slightly moist sites. They thrive where the average annual temperature is 20 to 30 Â°C. Germination is achieved only when soil temperature exceeds 28 Â°C. Baobabs are extremely susceptible to frost throughout their life cycle.
Land preparation is done in the summer or at the onset of the rainy season to preserve the soil structure. The soil
should be ploughed 3 to 4 weeks prior to transplanting, then again after 15 days, and then again just before planting the seedlings. The soil should be leveled and have good drainage.
Seedlings are mainly raised and transplanted into the field at 10 m x 10 m spacing. The hole size is 60 cm x 60 cm x 60 cm, but smaller may be suitable (40 cm3). The trees, planted in a row, should be given weekly volume of water which vary from 10 l for the first tree, 15 l for the second and 30 l for the third. Planting is done when the rainy season has started. Cuttings should be 5 cm to 10 cm in length and pushed straight into the soil to a depth of about 2.5 cm. For leaf production only, planting should be done 0,2 m x 0,5 m and for leaves and fruit it should be 4 m x 4 m.
Baobabs can be propagated from seeds as well as vegetatively.
Vegetative propagation involves the growth of a new tree from a shoot, bud or cutting from a good-quality matureÂ tree. The trees have traditionally been propagated by transplanting naturally regenerated seedlings.
Wild baobab Tree
Organic and mineral fertilisers can be used and it is recommended to use farmyard manure, compost or green legume manures, especially at the time of planting for intensive leaf production.
The volume of water required varies with the size of the tree and is dependent on local climate. In general, during establishment, about 1 l to 2 l of water should be applied twice a week to the base of each young tree. The small trees can be irrigated regularly to produce higher returns from intensive leaf production and better growth. Mature baobab trees require no irrigation.
The weeds should be removed from around the tree during the early stages of growth.
Disease and pest control
Few small baobabs are ever seen nowadays because they fall victim to grazing by cattle and goats, ground fires, or picking by overzealous individuals (for soup leaves) but mature trees have few enemies. Neither cattle nor goats do serious harm. Not even overzealous pickers can seemingly set back a healthy old baobab. There are no serious pests and diseases of baobab. However, some fungal and viral diseases have been recorded and several insects attack the wood, fruit and young shoots. The most investigated common pests are:
â€¢ cotton bollworms Heliothis armigera, Diparopsis castaneaÂ and Earias biplaga;
â€¢ cotton-stainers (bugs) such as Dysdercus fasciatus,Â D. intermeius, D. nigrofasciatus, D. suberstitiosus,
Odontopus exsanguinis, O. sexpunctatus;Â â€¢ Oxycarenus albipennis as well as fl ea beetles, PodagricaÂ spp.
The newly emerged larvae feed on the leaf and foliage of the plants. Cotton bollworms tunnel into the fruits of theÂ baobab. They suck the sap of the leaves and young foliage.
The immature fruit drops.
Registered chemical fertilisers are recommended for use. A decoction of the kernels of Azadirachta indica (neem) can be used for insect control. Weeding can also be used as a control measure.
The baobab is a host for members of the Pseudococcoidae, the mealybugs, which can be vectors for virus diseases of cocoa and the cocoa capsid, Distantiella theobroma. In the Limpopo and Mpumalanga provinces of South Africa, a caterpillar, Gonimbrasia herlina, can feed on the leaves.
The caterpillar sucks the sap of the leaflets, mature and tender shoots, leaf petiole bases and young foliage. The
immature fruit drops. Chlorotic leaves and defoliation can be observed. The caterpillar feeds on the leaves.
The affected parts should be removed. The caterpillars can be removed by hand and crushed.
Baobab provides food, emergency water and fibre. It has also medicinal uses. Fibre from the stringy inner bark provides items (or is used for items) such as rope, thread, basket, nets, snares, fishing lines, strings for musical instruments, and a paper stock tough enough for banknotes. The fibre is even used for weaving. Some is woven into fabrics that are valued for making the bags used for carrying and storing everyday goods. Baobab trees supply food and traditional medicines for both humans and their livestock.
A refreshing drink, prepared from the pale yellow or whitish fruit pulp called cream of tartar, has been used to treat fevers, diarrhea and apparently also haemoptysis. The leaves are used against fever, to reduce perspiration and as an astringent. They also come in hardy in treating other afflictions: asthma, kidney and bladder diseases, insect bites, fevers, malaria and sores.
In the Limpopo Province the powdered seeds are given to children as a hiccup remedy. Under survival stress man can use many parts of the baobab as food or obtain water from its roots, branches or leaves. A crude, coffee-like beverage can be prepared by baking the baobab seeds. Many people find shelter from the blistering sun in the ample shade provided by its sturdy trunk. Young leaves when mixed with pepper and salt and added to a stew give it a good taste.
Young, fresh leaves are cut into pieces and cooked into a sauce. Sometimes the leaves are dried and powdered and used for cooking.
