Vitellaria

The shea tree grows in Africa.

It has fruit like big plums. The fruit has a soft part. It also has a large seed. This seed makes a fat called shea butter. People use this fat for food. They also use it for skin care. Some people use it to make soap. The tree can live for 200 years. It is a very special tree.

The shea tree grows in Africa. It lives in dry areas called savannahs. This tree can live for 200 years. It starts to grow fruit when it is 10 to 15 years old.

The fruit looks like a large plum. It is 4 to 8 centimeters long. The fruit has a soft pulp. Inside is a large seed. These seeds are rich in fat.

People make shea butter from these seeds. They roast and press the kernels. Then they boil and cool the liquid. This fat is used for many things. In Africa, it is a major food. It is also used for medicine. Some people use it to make black soap. In the West, it is used in cosmetics. These are products for the skin. Some people even eat caterpillars that live on the leaves. These caterpillars are a good source of protein. The shea tree is very important to many people.

The shea tree is a very special plant found in Africa.

It is known by many names, like vitellaria or the shi tree. This tree is very important for many people living in Africa. It can help improve nutrition and support rural development. The tree also helps with sustainable land care. People use many parts of the tree for food and medicine. It is a vital part of life in many regions.

Making shea butter is a careful way it works. First, people collect the fruit from the tree. Inside the fruit is a large, oil-rich seed. To get the fat, workers roast and press the kernels. This creates a liquid that must be boiled and sieved. After it is cooled, it becomes shea butter. This fat is a complex substance with vitamins A, E, and F.

Scientists have studied this tree for a long time. The name Vitellaria paradoxa is the oldest scientific name. It was first published back in 1807. In the late 1800s and much of the 1900s, people called it Butyrospermum parkii. That name honors Mungo Park, a Scottish explorer. He learned about the tree while exploring Senegal. Even today, many people in the cosmetics trade use the old name.

These trees grow in a large area of Africa. They live in the dry savannah belt. This area goes from Senegal in the west to Sudan in the east. The trees grow in 19 different countries. These include nations like Ghana, Mali, Nigeria, and Uganda. A single tree can produce nuts for up to 200 years. It starts making fruit when it is 10 to 15 years old. Full production happens when the tree is 20 to 30 years old.

Many things you use every day come from this tree. In the West, shea butter is often an emollient for skin. An emollient is something that softens the skin. In Africa, it is a major source of dietary fat. In Ghana and Nigeria, it helps make African black soap. Even some insects depend on the tree. The Cirina butyrospermi caterpillar feeds only on shea leaves. People collect these caterpillars to eat as a protein source.

The shea tree, scientifically known as Vitellaria paradoxa, is a vital plant species native to Africa. It belongs to the Sapotaceae family and is the only species within its genus, making it a monotypic genus. This tree is much more than just a part of the landscape. It serves as a traditional food plant and a major resource for many communities. Experts believe it has the potential to improve nutrition and boost food supplies during the "annual hungry season." Furthermore, it can support rural development and help with sustainable land care across the continent.

The tree has a unique life cycle that requires significant patience. A shea tree begins to bear its first fruit when it is between 10 and 15 years old. It does not reach full production until it is roughly 20 to 30 years old. Once it reaches this stage, the tree is incredibly long-lived. It can continue to produce nuts for up to 200 years. The fruits themselves resemble large plums and measure 4 to 8 centimeters in length. Each fruit weighs between 10 and 57 grams and takes 4 to 6 months to ripen.

Extracting shea butter involves a specific sequence of traditional steps. First, the fruit is harvested to reach the large, oil-rich seeds inside. These seeds are known as kernels. To extract the fat, workers roast and then press these kernels. This process produces a liquid that must be boiled and sieved to ensure purity. Once the liquid is cooled, it becomes the solid fat known as shea butter. This butter is a complex fat containing various fatty acids. These include oleic acid, which makes up 40% to 60% of the composition, and stearic acid, which accounts for 20% to 50%. It also contains linoleic, palmitic, linolenic, and arachidic acids, along with vitamins A, E, and F.

The shea tree is divided into two distinct subspecies based on its location. The first is Vitellaria paradoxa subsp. paradoxa, which grows from the Nigeria-Cameroon border westward. The second is Vitellaria paradoxa subsp. nilotica, which grows from that same border eastward. These trees thrive in the dry savannah belt of Africa. Their habitat covers more than 670,000 square kilometers. They are found in 19 different countries, including Senegal, Mali, Nigeria, and Ethiopia. This wide distribution makes the tree a cornerstone of the African environment.

History shows that humans have relied on this tree for centuries. Evidence of shea butter production was found at the site of the medieval village of Saouga. This suggests people were using the tree as early as the 14th century. The scientific naming of the tree has also changed over time. The name Vitellaria paradoxa is the oldest, published in 1807. In the late 19th and 20th centuries, it was often called Butyrospermum parkii. This name honors Mungo Park, a Scottish explorer who studied the tree in Senegal. While some in the cosmetics trade still use the old name, botanical rules now favor Vitellaria.

Shea butter provides immense nutritional and economic value. The fruit pulp is very high in vitamin C, containing 196.1 mg per 100 grams. For a child aged 4 to 8, just 50 grams of pulp provides 332% of their recommended daily intake. For pregnant women, that same amount provides 98% of their daily requirement. The kernels are also rich in fat, ranging from 17.4 to 59.1 grams per 100 grams of dry weight. This fat has antioxidant and anti-inflammatory activities. Beyond food, the butter is used for medicine and as an emollient in cosmetics to soften skin.

There are many fascinating connections between the shea tree and other life forms. For example, the moth Cirina butyrospermi depends entirely on the tree. Its caterpillars feed solely on the leaves of the shea tree. These caterpillars are protein-rich and are widely collected by people to be eaten raw, dried, or fried. In some cultures, the tree is deeply integrated into social traditions. In the Lango and Acholi cultures, shea butter is used to enthrone traditional leaders. In Ghana and Nigeria, it is a key ingredient in making African black soap. The tree's importance is even reflected in place names, such as the city of Tamale. The name Tamale is derived from 'Tama-yile,' which means 'Home of Shea nuts.'
