According to Traditional Chinese Medicine, wei (or defensive qi) is located on the surface of the skin.
When the wei is strong, viruses and bacteria cannot penetrate the body. When it is weak, the body is
susceptible to a variety of infections. Therefore, prevention from illness relies on the normal functioning
of the wei qi.


Vitamins A, C, E and Zinc are essential in promoting a healthy immune system
Drink plenty of fluids
Eat foods that strengthen the body and fight off infection, (e.g. garlic, citrus fruits, green vegetables)
Limit the intake of refined sugars; they impair the body’s ability to kill bacteria and fight off infection
Specific Chinese herbs taken regularly can provide protection against foreign or pathogenic factors
