In foreground, freeze-dried cotton hairy roots (from which gossypol is extracted). In background, gossypol (in powdered form). Gossypol is a yellow pigment that accumulates in a cotton plant’s outer tissues. The pigment is being investigated not only for its abilities to suppress numerous microbes, parasites, fungi, and insects, but also for inhibiting growth of some cancers.
