Energy is a fundamental concept in Chinese medicine, often compared to blood. Energy circulates in the body in the same way as blood, and like blood, energy can circulate too slowly, too quickly, or irregularly. When energy flows upwards, it can cause hiccups and vomiting; when it flows downwards, it can cause prolapse of the anus, uterus, or stomach. When energy flows too slowly, it can cause chest pain and depression.
The class of herbs that regulate energy is used to make energy circulate smoothly in the body, and one such herb is yellow jasmine. Ailments often treated by this class of herbs include chest pain, pain in the ribs, abdominal pain, vomiting, hiccups, prolapse of the anus, uterus, or stomach, menstrual pain, enteritis, and acute bronchitis.
However, herbs in this class travel very fast in the body, so they can use up a great deal of energy, similar to a car that runs fast using up a lot of gas and oil. For this reason, this class of herbs should not be used for a prolonged period.
Chinese medicine classifies energy as yang and blood as yin. They are sister and brother, with energy as the brother and blood as the sister, and they travel in the body hand in hand. To ensure that they travel smoothly together, the herbs that regulate energy and the herbs that regulate blood (class 12) are often used together.
