General
...Orally, watercress is well-tolerated when consumed in food amounts.
There is limited reliable information available about the adverse effects of watercress when used in medicinal amounts. When excessive doses are used, watercress can cause gastrointestinal irritation (85599). Consuming raw watercress has been associated with the development of fascioliasis, a parasitic fluke disease of the liver (85575,85574,85573,85567,85564,85582,85563,85562,85580,85561,85560)(85554,85558,85596,85579,85571,85569,85583,85586,85584,85588)(85585,85590,85592,85591).
Topically, watercress can cause contact dermatitis (85594,85587).
Dermatologic ...Topically, watercress can cause contact dermatitis, resulting in hives, rash, itching, or swollen skin (85594,85587).
Gastrointestinal ...Orally, large quantities of watercress may cause gastrointestinal irritation (85599).
Hepatic ...Raw, wild watercress can be contaminated with parasitic flukes which, when ingested, cause the liver disease fascioliasis. Symptoms include abdominal pain, fever, vomiting, diarrhea, urticaria, eosinophilia, and hepatomegaly (85575,85574,85573,85567,85564,85582,85563,85562,85580,85561)(85560,85554,85558,85596,85579,85571,85569,85583,85586,85584)(85588,85585,85590,85592,85591). Clinical research shows that taking a standardized extract of watercress orally 750 mg/kg daily for 5 weeks is not associated with increases in liver function enzymes (109666).
Renal ...Orally, excessive or prolonged use of watercress may theoretically cause kidney damage (85598). However, in overweight adults with physical disabilities, taking a watercress extract 750 mg/kg daily for 5 weeks does not cause any change in levels of creatinine or urea (109666).
