occurs in edible cruciferous vegetables. Produced from glucosinolates in Brassica sp. on crushing or cooking. Potential nutriceutical 16082211).; Indole-3-carbinol is produced by members of the family Cruciferae and particularly members of the genus Brassica, for example, cabbage, radishes, cauliflower, broccoli, Brussels sprouts, and daikon). Indole-3-carbinol is metabolized to a number of products, including the dimeric 3,3'-diindolylmethane. Both 3,3'-diindolylmethane and Indole-3-carbinol are thought to have biological effects. Indole-3-carbinol is a natural chemopreventive compound. It has multiple anticarcinogenic and antitumorigenic properties by suppressing the proliferation of certain cancer cells, including breast cancer, prostate cancer, endometrial cancer, colon cancer, and leukemic cells (PMID: 16634522
