googled isothiocyanate

First result

Isothiocyanates are naturally occurring small molecules that are formed from glucosinolate precursors of cruciferous vegetables. Many isothiocyanates, both natural and synthetic, display anticarcinogenic activity because they reduce activation of carcinogens and increase their detoxification. Recent studies show that they exhibit anti-tumor activity by affecting multiple pathways including apoptosis, MAPK signaling, oxidative stress, and cell cycle progression. This review summarizes the current knowledge on isothiocyanates and focuses on their role as potential anti-cancer agents. [1]

The source on wikipedia, the second result

Isothiocyanates may modulate the expression and activity of biotransformation enzymes that are involved in the metabolism and elimination of xenobiotics (e.g., carcinogens) from the body. In cultured cells and animal models, isothiocyanates also exhibited antioxidant and anti-inflammatory activities and interfered with numerous cancer-related targets and pathways. (More information)

Although high intakes of cruciferous vegetables have been associated with a lower risk for cancer, there is insufficient evidence that exposure to isothiocyanates through cruciferous vegetable consumption decreases cancer risk. (More information) [2]

And the jackpot you find on Wikipedia that motherfuckers take to task as surely as the sun rises "Although there has been some basic research on how isothiocyanates might exert biological effects in vivo, there is no high-quality evidence to date for its efficacy against human diseases[Link to [2]]." It's always that. That's the wisdom that these people subsist off of. That is why you can't do porn, seed oils, hot showers, shampoo, etc.
