Even though it’s cold and flu season, not everyone gets sick. If you’re able to fend off a contagious cold or flu, it may be because you have strong Wei Qi (pronounced “way chee”) according to oriental medicine experts. On the other hand, if you seem to catch every virus going around, you may have weak Wei Qi.
“Wei Qi is another way of referring to the body’s immune system or first defense against infection,” says Dr. Yihyun Kwon, a faculty member in the acupuncture and oriental medicine program at National University of Health Sciences.
