四、The nourishment vegetable of the paddy field Jie plant:

Have already studied the plant nourishment vegetable contained to include from the paddy field Jie currently:


Type the flavonoid is plain(Flavonoids):

Have anti- oxygenation, can prevent cholesterol from accumulating in on the artery in the meantime, and avoid the blood coagulation whole piece with reduce the probability of the artery hardening occurrence.Type the flavonoid vegetable can also stop the bad activity of some hormone, repressing an enzyme activity of causing the inflammation, can also repress capillaries to increase to get.
