Unlike industry-standard petroleum-based dyes, this shirt is dyed with natural plant dyes from madder root and cochineal.
Madder root is one of the oldest natural dyes, known for its ability to make beautiful reds. It has been safely used for thousands of years, since at least ancient Egypt (cloth dyed with it has even been found alongside the possessions of King Tut).
Cochineal is a traditional dye originally used by the Aztecs and Mayans of Central and North America. Cochineal, also called carmine, is an FDA approved natural food colorant. Cochineal is extracted from small scale insects that infest prickly pear cactuses.
