Shea nuts are known in the
local Dioula language as
karite
(life). They grow mostly in
the wild with little need for any special cu
ltivation. The shea nut tree grows in abundance
and is one of the few renewable resources in
the semi-arid Sahel region of West Africa. It
is found in a belt about 300 kilometres wide
extending from Mali through Burkina Faso
to Ghana, Togo and Benin. This ‘shea belt’ is
the only place in the world where the tree
grows. The largest concentration is found in
Burkina Faso, across more than 80 per cent
of the country. The shea tree has a very long lif
espan of up to 200 years. It produces fruit
after its fifteenth year, but does not reach full
production until it is 25 years old. The shea
tree has many uses: the bark is used as an
ingredient in many traditional medicines
against childhood ailments and
in the treatment of minor
scrapes and cuts. The shell
serves as a mosquito repellent – vital in a
region where malaria kills thousands of people
a year. The shea tree also helps prevent wind
erosion and adds organic matter back to the
soil. The nuts are processed
to obtain shea butter, which
is used as cooking oil, for
making soap, as medicine, and in cosmetics.
In many western countries shea butter is
highly prized for its superb h
ealing and moisturising properti
es and is widely used in
creams, sunscreen lotions and conditioners and
in the treatment of bur
ns and muscle pain.
It is also used in chocolat
e manufacturing, since it comple
ments cocoa very well, and is
processed into baking fat, margarin
e, and cocoa butter substitutes.
Traditionally, shea nut harvesting and pro
cessing are rural women’s work. The women
would individually collect the
nuts of the wild-growing shea
tree and conve
rt them to
shea butter in a very labour-int
ensive process. Only small
quantities of shea nuts were
processed into butter, however. The women
would grind the nuts by
hand, press them –
often walking several miles to a press in anot
her village and back to
carry out this stage
of the process – and boil and filter the oil
