Indole-3-carbinol is formed from a substance called glucobrassicin found in
vegetables such as broccoli, Brussels sprouts, cabbage, collards, cauliflower, kale,
mustard greens, turnips, and rutabagas. Indole-3-carbinol is formed when these
vegetables are cut, chewed or cooked. It can also be produced in the laboratory.
People use indole-3-carbinol for conditions such as cancer prevention, systemic lupus
erythematosus, tumors inside the respiratory tract, and many other conditions, but
there is no good scientific evidence to support these uses.
