Chinese pharmacy. Woman dispenses herbal medication in a Chinese pharmacy. The woman is holding a box of medication which she is dispensing onto white paper sheets. Behind her are many other boxes of medicinal stocks such as cut herbs and sliced horns. Herbalism is a system of medicine in which parts of plants are used to promote health and treat symptoms. Chinese medicine is based on the theory of a universal bodily life force, Chi. This is balanced by two complimentary qualities, yin and yang. Imbalance in yin & yang and disruption of the flow of Chi causes illness. Chinese medicine balances yin & yang and the flow of Chi. Photographed in Korea.
