Shea butter, derived from the nuts of the African shea tree (Vitellaria paradoxa), is renowned worldwide for its exceptional moisturizing and healing properties. This natural fat has been a staple in African skincare and cuisine for centuries, valued not only for its rich texture but also for its numerous beneficial compounds.
Origins and Extraction
Shea butter originates predominantly from West Africa, where the shea tree grows abundantly in the savannah regions of countries such as Ghana, Burkina Faso, and Nigeria. The process of obtaining shea butter involves several traditional methods, typically beginning with the collection of ripe shea nuts that fall from the tree.
