Shea butter comes from the nut of the shea tree, which grows in West Africa. It has been used for centuries in Africa for various skin protecting effects.
Shea butter has been marketed as a skin and hair moisturizer and as a treatment for a variety of skin conditions including acne, burns, chapped lips, dry skin, eczema, psoriasis, scars, stretch marks, and wrinkles. It has also been used as a cream to relieve arthritis and rheumatism and to heal bruises and muscle soreness, however, there is questionable evidence to support these uses of shea butter.
Based on human study, shea butter may be effective for relief of nasal congestion, lowering cholesterol levels, and for blood thinning.
