The Yin-Yang theory holds that disease is a result of an imbalance between yin and yang which leads to the hyperactivity or hypoactivity of yin and yang. The occurrence and the development of a disease are also related to zheng qi (body resistance or antipathogenic factors) and xie qi (pathogenic factors). The Yin-Yang theory can be used to generalize the interacting relations between body resistance and antipathogenic factors.
1 Colposcopy is a procedure used by physicians that provides a magnified and illuminated view of the vulva, vaginal walls, and uterine cervix. 2  This procedure is often done to evaluate an abnormal appearing cervix or an abnormal Pap smear result.
A colposcopy is a way for your doctor to closely examine your vagina, vulva (vagina opening) and cervix. A colposcope is an instrument that your doctor uses to shine a light on the cervix and magnify the view.At the beginning of the colposcopy, you lie back and place your feet in the stirrups as you would for a Pap smear.Your doctor inserts a speculum into your vagina and opens it slightly so he or she can see your cervix. Then your doctor applies a vinegar solution to the cervix and vagina with a cotton ball or swab.The vinegar makes abnormal tissue turn white so your doctor can identify areas that may need further evaluation. If your doctor sees areas of abnormal tissue during the colposcopy, he or she may also perform a biopsy.hen your doctor applies a vinegar solution to the cervix and vagina with a cotton ball or swab.
