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.
The colposcopy generally includes an ECC, in which the endocervical canal is scraped more vigorously than in a Pap test. The samples are placed in jars of fixative and sent to the lab. A diagram of the cervix is kept in the womanâs chart to document where the samples were taken from.
