The isothiocyanates are naturally occurring small molecules found mainly in some cruciferous vegetables. These belong to the Brassicaceae family.
Isothiocyanates are produced by plants in response to stress, acting as a defence mechanism which triggers a variety of physiological changes in the plant to aid survival.
Yes you can! Isothiocyanates have quite a characteristic bitter taste. In the example of watercress, PEITC is what gives us the pepperiness.
Absolutely! Chewing watercress creates and releases PEITC. It also has a range of other health benefits too. Our research has demonstrated that to get as much PEITC from watercress as possible, you would have to chew into a paste for over 2 hours, which probably isn’t that appealing!
Eating watercress, while superbly good for you and actively encouraged, only gives you a fraction of the dose of PEITC that our extract delivers.
