The shea tree grows wild across a 5,000-kilometer belt stretching from Senegal to Ethiopia, thriving in the dry savannah where few other trees survive. It's a patient tree—taking 10 to 15 years before producing its first fruit, reaching full production only at 20 to 30 years old, and living for up to 200 years.

This doesn't mean other butters are ineffective—it means we have less scientific evidence to evaluate their claims. When you see research cited for "plant butter" benefits, check whether the studies actually used the specific butter being marketed, or if they're extrapolating from shea butter research.

Approximately 85 to 90 percent of shea butter's fatty acid composition consists of just two molecules: oleic acid and stearic acid. This might sound like oversimplification, but the ratio of these two acids determines everything from texture to skin penetration to therapeutic effect.
