Watercress is categorized by Chinese Medicine as cool in nature and sweet and pungent in taste. It acts on the lungs, has a cooling effect and promotes vital fluids to lubricate the lungs and relieve cough.
Watercress is commonly used in Chinese cuisine as the main ingredient for making soup, congee and dumplings or is eaten just as a plain vegetable dish. It is mostly consumed in the summer months for its cooling effect and in fall for its moisturizing properties.
In fact, watercress has its origin in the West. The Chinese name for watercress is ‘sai-yeung-choi’ which means western vegetable. Historically, watercress was used by the Romans, Greeks and Persians as a natural medicine, prescribed for migraines, anemia, eczema, kidney and liver disorders and tuberculosis.
According to modern research, watercress has been found to be the new miracle food with anti-cancer properties.
A study published in The American Journal of Clinical Nutrition in February of 2007 showed that, in addition to reducing DNA damage, a daily dose of watercress increased the ability of cells to further resist DNA damage that may be caused by free radicals. In the study, 60 men and women, half of whom were smokers, consumed their usual diet plus 85-grams of raw watercress daily for 8-weeks. Blood samples were analyzed for plasma antioxidant status and DNA damage in lymphocytes, a type of white blood cell. Watercress consumption significantly reduced lymphocyte DNA damage.
Another study published recently in The British Journal of Nutrition, the consumption of a three ounce portion of watercress reduced the presence of a key tumor growth factor six to eight hours after eating the watercress in healthy patients who had previously been treated for breast cancer. The study was conducted by the Cancer Research Center at the School of Medicine, Southampton General Hospital in the United Kingdom and concluded watercress is as therapeutic as traditional drug treatments with tamoxifen & herceptin, commonly used chemotherapy drugs.
The study also said that through regular consumption, watercress “has the potential to confer valuable protection against cancer in general. Watercress has the ability to turn off HIF1, a signal sent out by cells calling for blood supply,” said noted aging scientist Dr. Nicholas Perricone. *When HIF1 becomes incorrectly regulated, otherwise harmless precancerous clusters of cells have the opportunity to grow to form invasive tumors. Scientists have been looking for anti-angiogenesis agents for years because if we can turn off the blood supply, we can kill the cancer,” said Perricone. “And it looks like watercress can do that.”
Since watercress is available almost year round and is very inexpensive, we should eat a lot more of it for our health. Making watercress into a plain vegetable dish is really simple. Just put watercress in boiling water with a spoon of salt and some oil and blanch it for a few minutes and serve. Putting watercress into soup makes it easy to eat a lot more of it in one serving.
