The Sheanut Tree, The wonder tree
“Can you borrow me some sheabutter?’. This is the commonest product that people ask for immediately the hammattan season starts in the Northern, Upper East and Upper West Regions of Ghana. These three regions experience the severest form of hammattan brought on by the North East Trade Winds blowing across the Sahara Desert. The hammattan takes a heavy toll on the human skin, drying it up and cracking it as well as the human hair which becomes very dry and brittle and starts to break or fall off. It is not uncommon to find people bleeding from cracked lips during this period or their hair falling off due to its brittleness because of the dry weather. But thanks to the moisturizing power of sheabutter, the situation can be brought under control. It is for this reason that those who did not stock the butter in preparation for the hammattan have to borrow some to use while they replenish their own stock.
Sheabutter is derived from the sheanut tree, with the botanical name Butyrospermum parkii or Vitellaria paradoxa and is a common wild tree that grows extensively in the dry Savannah belt of West Africa, stretching from Senegal in the west to Sudan in the east. The sheanut tree also thrives along the foothills of the Ethiopian highlands. Apart from Ghana, the tree can be found in 18 other countries including Benin, Chad, Burkina Faso, Cameroon, Central African Republic, Ethiopia, Guinea Bissau, Cote D’Ivoire, Mali, Niger, Nigeria, Senegal, Sierra Leone, Sudan, Togo Uganda, Zaire and Guinea. In Ghana, it grows extensively in the Guinea savannah but is less prolific in the Sudan Savannah. It covers a landmass of about 77,670 square kilometers in the Northern, Upper East and Upper West Regions of Ghana. A few sheanut trees are also found in the Brong-Ahafo, Ashanti, the Eastern and Volta Regions in the southern parts of the country.
The fruit consists of a green fleshy mesocarp, which is sweet when eaten and in very ripe fruits seems to melt on the tongue when the fruit is bitten. It is also used to make jam. The mesocarp has a high nutritional value and contains between 0.7 to 1.3g of protein and 41.2g of carbohydrate. The fruit pulp is also a rich source of ascorbic acid and contains196.1mg/100g in comparison with an orange, which contains only 50mg/100g. The iron and calcium content of the mesocarp of the sheanut compares favorably with that of raspberries. Sheanuts contain 1.93mg/100g of iron as against 0.92mg/100g in raspberries. Sheanuts also contain 36.4mg/100g of calcium as against 26mg/100g for raspberries. Apart from these micro nutrients, sheanuts contain the B group vitamins and a sugar level of about 3 to 6 percent which is equally distributed among glucose, fructose and sucrose. Even the flowers of the sheanut tree are consumed by some ethnic groups that make them into edible fritters. The nuts are cracked to remove the outer cover leaving the endocarp or kernel which is roasted and ground into a paste from which sheabutter is extracted. The nuts also serve as toys for children, who use them to play a game known as “maranda”, the common name given to the nuts in Ghana.
All parts of the sheanut tree are of immense value. In some communities, the leaves are used as medicine to treat stomachache in children. In Ghana a decoction of young leaves is used as a vapor bath for the treatment of headaches and also as an eye bath. When the leaves are put in water, it forms a frothy opalescent liquid, which is used to bath the head of the patient. A leaf decoction is also used as an eye bath. Because the leaves contain saponin, they lather in water and are suitable for washing. The leaves of the sheanut tree are used as a preservative and in the processing of dawadawa, a local spice in Ghana. They are used to cover dawadawa after processing for a period of time for it to ferment. The leaves of the sheanut tree are also believed to offer spiritual protection. Hence, in some African communities when a woman goes into labor, the branches may be hung in the doorway of her hut to protect the newborn baby from evil. Some communities also use its branches for covering the dead prior to their burial.
In Nigeria, the roots of the sheanut tree are used as chewing sticks especially in the savannah areas. The roots and the root bark are sometimes ground into a paste and taken orally as a cure for jaundice in Ghana as well as the treatment of diarrhoea and stomachache. The root bark is also boiled and pounded and used for the treatment of chronic sores in horses. Nonetheless, the tree can also be employed by the unscrupulous for foul means. Among the Jukun tribe of Nigeria, the roots are mixed with tobacco to produce poison.
In Ghana, the bark of the sheanut tree is boiled and taken as a beverage and there are claims that this beverage can treat diabetes.
However, scientific studies indicate that infusions of the bark has selective anti-microbial properties. It has been found to be effective against Sarcina lutha and Staphylococcus mureas. However, the bark infusion does not treat mycobacterium phlei.
In Senegal and Guinea, worm infested cattle have been treated with infusions of the bark which are crushed together with the bark of Ceiba pentandra and salted. Ailments ranging from diarrhea and dysentery to gastric problems and even leprosy have been treated with bark infusions in Guinea Bissau. In the Ivory Coast, a bark decoction is used in baths and other therapeutic sitz-baths to ease child delivery of women in labour. It is also drunk by lactating mothers to boost the flow of milk. This practice, however, is abhorred in Northern Nigeria where the concoction is considered to be lethal. A bark infusion has the capacity to neutralize the venom of the spitting cobra when used as an eye wash. It is also used in Ghana as a foot bath to help extract jiggers.
The sheanut tree produces copious amounts of sap which can prove invaluable in the gum and rubber industry. This latex when heated and mixed with palm oil produces glue. It is even chewed as a gum by children who also play with the balls that are made out of the gum. Bobo musicians in Burkina Faso use this gum to fill up cracks on their drums and punctures on their drumheads. However, latex from sheanuts contain between 15 to 25 percent carotene which according to present technology makes it inappropriate for the commercial manufacture of rubber.
The brownish husks that are separated from the nut to release the kernel also have the ability to purify water and can remove substantial amounts of heavy metal from aqueous solutions. They are also pounded and used for plastering traditional mud houses to beautify them and promote their lifespan by making them impervious thus reducing their absorption of moisture.
While the tree has so many uses, it is well known for the production of sheabutter. Sheabutter production involves various stages, beginning with de-pulping, to get rid of the fleshy fruit. This is achieved by fermentation which is enhanced by initial boiling or burying the fruit. Following de-pulping, the nuts are sun-dried for five to ten days. When temperatures are below 50 degrees Celsius, drying can go on for several days but at 50 degrees Celsius, the desired moisture content of six to seven percent is archived between four to five days. The nuts are de-husked through trampling, pounding them in a mortar using a pestle or crushing them using two stones to get rid of the brown cover leaving only the kernel.
The kernel is then crushed and baked or roasted over carefully monitored heat to prevent it from being charred since charred kennels would lower the quality of sheabutter produced by reducing its fat content. Roasting promotes fat concentration and latex coagulation and prolongs the shelf life of the nuts. Those that attain a moisture content of seven percent after roasting can be stored for two years.
Extracting butter from the baked kernel involves grinding it into a fine powder which is then mixed with warm water. The resulting semi-solid mixture is then kneaded or stirred continuously to form a paste. The paste is left standing and with time oil collects on it which is collected periodically, finally leaving behind a brown residue after all the oil has been collected.
Sheabutter serves as a moisturizer and is naturally rich in vitamin A, E and F in addition to some other vitamins. It is thus able to sooth, balance and hydrate the skin. It also contains collagen which reduces wrinkles and other signs of aging while the essential fatty acids contained in vitamin F help to revitalize and protect damaged hair and skin. It thus promotes skin renewal, increases circulation and speeds up the healing of wounds. It is estimated that about eight percent of the fat in sheabutter is medicinal and even as far back as 1728, its medicinal properties were recognized and used by Africans. The low melting point of sheabutter which is between 32 to 45 degrees Celsius and close to body temperature coupled with the presence of allantoin, which stimulates the growth of healthy tissues in ulcerous wounds, makes it ideal as a base for ointments and medicines. The butter is thus a healing balm whose uses are a myriad. According to Mr. Saibu Dawuda Wanzam, a Circumciser, sheabutter is the sole medicine used to treat the wounds of newborn babies following circumcision. “After an infant male is circumcised, melted sheabutter is applied to the wound which heals within three to four days. It is important that the mother applies melted sheabutter to the wound every 30 minutes to one hour to hasten its healing”, he says.

The butter is also applied to the umbilical cord of new born babies to hasten its healing. It is also the preferred body cream for new born babies among educated and illiterate mothers alike in Ghana, who believe that the baby creams found on the market have been adulterated or contain chemicals that are not suitable for baby skin. It is especially useful for massaging the bodies of babies during their daily bath. Sheabutter is deemed pure and contains natural moisturizers and vitamins that give babies a smooth skin. Scientific studies that involve measuring moisture on the skin using a corneometer suggest that sheabutter leads to a consistent increase in moisture levels of users for over four hours. No wonder it is the best defense for the skin during the hammattan season
Sheabutter is also an important part of the diet of people living in the areas where it grows and it is used for frying and making stews. It is sometimes smeared on Tuo Zaafi (TZ), the staple food of people in the three northern regions of Ghana to prevent the meal from drying up and forming a dry upper crust during hammattan.
The left over residue after the oil has been processed is used to decorate traditional mud houses. This thick brownish residue is also mixed with clay to harden it and make it stronger before it is molded into mounds for building.
However, recent research carried out at the Tamale Polytechnic by Hajia Adiza Sadik and one of her students at the HCIM department led to the production of chocolate bars and chocolcate spread from the residue using the same recipe used to manufacture chocolate. According to Hajia Sadik, the residue that is either thrown away or used as animal feed contains a lot of vitamins and the production of shea chocolate bars and shea chocolate spread could enhance the utilization of the sheanut tree and provide additional jobs and income for rural women.
One would have thought that given the numerous benefits of the sheanut tree, the tree would be cultivated on large farms in the northern parts of Ghana. However, this is not the case. The tree grows wild in the bush at the mercy of bushfires and charcoal burners because the best charcoal comes from the sheanut tree. However, Mr Peter Kale, a former manager of the Church Agricultural Inputs Project in Tamale thinks the sheanut tree can be cultivated.
Mr kale said sheanuts require a unique way of planting in order to germinate. “If you plant the whole seed underground which is the norm with other plants, it would not germinate. The eye of the seed should face up and should not be covered by soil. Thus, the seed should be half-buried in the soil.”
“It is for this reason that when the nuts are thrown around haphazardly after eating they germinate after a season but would not germinate when they are carefully planted in the traditional way which gives the impression that they can only grow in the wild,” he said.
“A tree would normally fruit after six to seven years if it has not been subjected to severe bushfires but those that have been subjected to severe bushfires become stunted and may require up to 10 years to fruit”, Mr Kale explained.
The tree flowers between late February and April and if it is not exposed to bushfire, the flowering is good leading to a bumper produce. Bushfires during the flowering period make the flowers to wither and drop off. However, early bushfires around early January do not impact much on its fruiting since the heat is less intense and flowering has also not started. With the inception of the rains, the fruits develop and mature around late May to June.
Scientific research into the tree has been going on in Ghana at the sub-station of the Cocoa Research Institute of Ghana (CRIG) at Bole in the Northern Region which was established in 1976 by the Ghana Cocoa Marketing Board (GCMB). Research on the tree was prompted by the need to find a substitute for cocoa in the confectionary and cocoa butter industry. The institute has been able to foster the vegetative propagation of the sheanut tree and also reduce its maturity period from 20 to seven years.
Sheabutter processing and extraction remains the major economic activity of most rural women. Given its medicinal, cosmetic and nutritional values, it is on high demand internationally and is exported to earn foreign income for rural women. It is for this reason that a sheabutter processing factory was commissioned by Mr John Mahama, Vice President of Ghana, in the year 2010 in the Northern Region of Ghana.
keep it up and try to up date me at all time you come out with any research on the sheabutter. by the way how is it related to agribusiness and how can it be produce on commercial base?
It is linked to agribusiness in that women collect the nuts from the wild and process them into sheabutter to sell on the market. Some is also exported. There was a time when the owners of Body Shop visited some sheanut processing groups in Tamale because they import the sheabutter for the making of cosmetics.
On how it can be produced commercially, a Research Station at Bole has researched on how it can be planted on a large scale. But so far, no one has cultivated it commercially probably because there is so much of it out there in the wild which is not even utilized.
Great information thank you!
I would like to know more about cultivation Shea tree on a large scale.. Please any links to the research station at Bole you mentioned?
I am Nigerian
Thank you
Bernice , thanks for this wonderful piece -that,s brilliant.But i want to know if its only in the NORTH that it can be cultivated and what is the maturity period
Thanks for the opportunity and look forward to your respone .
Even though the sheanut tree is found extensively in the north, it thrives in some parts of the Volta Region and the Brong/Ahafo Region. The maturity period for the sheanut tree growing in the wild is normally very long but research conducted by the Cocoa Research Institute (CRI) sub station at Bole has come out with a scientific breakthrough for reducing its maturity period from 20 to seven years. This story was carried in 2008 by a website with the address: http://www.ghanabusinessnews.com/2008/12/08/ghanas-scientific-breakthrough-in-growing-shea-nuts-for-economic-development/
This is a really amazing and informative blog. I have been looking for information about the Shea Tree and voila! I find all the information I need right here in this blog. Amazing!!!
Fantastic fantastic decription to this all important comodity Ghana has nuglected and focusing their effort on only cocoa. Thank you Bernicew for this insite. It has indeed being very helpful to me in quest to research into sheanut. I will continue to follow your bloggings and twitter as well. God bless you. Evans
Thanks Evans for your kind words and encouragement. The truth is we are neglecting most of our local economic trees. One other tree that has been neglected is the dawadawa tree which is becoming more scarce yet nothing is being done to protect it or to propagate it.
Fineooo!,please continue to update me when come up with new research.meanwhile i want to know wheather it is use in the treament of tuberculosis.THANKS
Thanks for your comment. Unfortunately, I have not yet come across any literature that links this product with the treatment of tuberculosis. If I do I will let you know. I will also keep you updated with new research findings. In fact, I recently got to know of some traditional uses of this product and I would be updating the article soon.
I am in Ethiopia and how can I find the natural shea butter displayed in your article? No body sell shea butter here
I am very sorry about that. In Ghana, sheabutter is one of the commonest products on the market and it is sold at a relatively low price. The problem is I do not know how I can get it over to you in Ethiopia. Do you have any suggestions?
sorry for late response. But can you use postal service? you know I wanted it for medicinal purposes (for skin problem)
i know some people who are working with the shea butter here in ethiopia.if you send me your email i will give you their adress.you can have contact with them and get an information.
This is great news. I will send you an email so that you can connect me with those people.
I recently got into the Shea nut industry and i find this article highly informative. Good job Bernice!
Thanks. I am happy to hear you found this article informative.
sori 4 e late resp.av learned a lot.pls dnt 4gt to update me more on any of ur findings.GOD IS REALLY GREAT.
you are doing a great job, we have sheabutter here in Nigeria too. am planing to go into agribusiness too.
Thanks for your kind words, Adakole. I am happy to hear you plan going into agribusiness. Have you found ways of adding value to the sheabutter? I think that is what we need to do now to increase its market value.
thanks, how is the business go over there in Ghana, what kind of agribusiness can you advice me to go into, and how to get foreign buyer.
The sheabutter business in Ghana has not always been lucrative. Most of the producers do not find foreign buyers for their produce and also lack the skills, expertise and financial assistance to add value to the produce. This I believe is the main problem; the inability to add value to sheabutter and market it in Ghana and neighboring countries.
With regards to the kind of agribusiness to go into, there are lots of opportunities and I cannot immediately pinpoint one.
I JUST FOUND YOUR SITE. I AM LIVING IN BOLGA, AND WE ARE INTERESTED IN THE BUSINESS. DO YOU HAVE ANY IDEA HOW MUCH THE SEEDLINGS COST OR IF THEY ARE AVAILABLE?
Datz interesting i find helpful for my research, presently am going for the practical aspect. That is the Extraction and proximate analysis of the butter. But pls i want knw if u knw the composition of a single shea nut. Thanks while waiting. for ur response
very educational and eye opening now do shea tree grow in the other two east african countries Tanzania and Kenya and if not can they be cultivated ? Thanks
Hello Kessy, I need to research on whether they do grow in Tanzania and Kenya and get back to you. As to whether they can be cultivated, I think it is now possible. A lot of research has been carried out in Ghana on how sheanuts can be cultivated and attempts have also been made to introduce varieties that have a shorter maturation period.
Adakole, You can follow the links below to see about research done in Nigeria on by some universities. I hope it will be of value to you.

Thanks Adakole for providing the links to the universities. They are definitely a great source of information and will be of great value to me.
I am an MPhil student, studying Post Harvest Technology and i will like to have my research work on shea, please can u help me get a research topic to work on.
I am interested in knowing more economic, social, food& medicinal uses of shear nut trees. how can I get seeds to grow?
what are the varsities of shear nut tree?
Thank you for the detailed information you provided about shear trees. I will use the literature to sensitive my community about this shear tree which is almost depleting in our society. many people especially the youth have been cutting down the trees for charcoal. thanks. cheers.

Thanks for your information, I personally live in a community which has been blessed with this tree species but we seem to misuse it just for fuel because it also produce agood fuel. I will need to start sensitising our people.
woow am so happy seeing this article.am a project student writing about shear butter and its economic importance to the women in ghana.this piece has helped me so much
thanks sharing this
Bernice, good research. I am getting valuable information on shea as a native of Northern Ghana. Your work surely will create the agribusiness for poor women in Northern Ghana. Keep it up. Thank you.
Thanks 4 dis beautiful write up. I want to start d farm in Nigeria. How do I get d improve seed. Await ur reply pls
Nice 1 Bernice, pls how some1 in Nigeria get the improved seed?
Everything about this article is REAL and TRUE .
I am a shear butter producer in tamale . Incase u need some, you can contact me on +233542911622 or hit me up on my email avsonprosper@gmail.com . thank you
Thanks a lot for this wonderful work the good strengthened you to continue in this direction. it will interest you to know that by this, you are bringing most youngsters dreams into reality just like me. God bless you for that.
Now my question is, I have a land which I have always dream to use for sheanut cultivation for about three years now coz I know it will be scarce in the future. So can I go ahead to plant it following the procedure explained in your research? and also expect to start harvesting about seven years?
Shea butter is also very beneficial to the penis. In addition to smoothing out and softening the skin, it makes it a lot more responsive as well. Men can find shea butter in a high-quality penis health creme, which will contain several other key vitamins and nutrients which will improve their overall sexual health.
Bernice that was a great piece, I really admire the work done. It has been informative. I grew up around the sheanut tree as well as the butter but I never knew the flowers are edible. Are they eaten the way the nuts are eaten or it is used as something else before they are eaten?
I want to get some fruits and try to cultivate, can you tell me on how to go about it. I’m from Nigeria
For more information about shea pls contact the shea unit of cocobod,you can reach
