Watercress PEITC and CYP2E1

In the body: no agency opinion we hold names an effect at the amounts found in food, so it is shown for context, not rated.

Not rated by dose: a flag on one reviewed food, watercress.

Background. Shown, not scored: no dose basis at normal intake, a classification rather than a risk, or legal limits only.

    Context

    PubMed 9728894 · grade B

    How it’s rated

    Context only. The study abstract names no compound (the link to phenethyl isothiocyanate does not come from a source read); no agency basis and no drug label naming watercress was found, so no flag. A 2002 study found no important effect on how fast alcohol is cleared.

    Intake: not applicable (flag) · Level in the food: 56 % increase in chlorzoxazone AUC (single human study, n = 10)

    Measured on: single ingestion of 50 g watercress homogenate, 10 healthy volunteers; chlorzoxazone is a CYP2E1 probe
