Moxibustion — traditional Chinese medicine In moxibustion, or moxa treatment, small cones of an herb (typically *Artemisia moxa*) are burned on top of needles placed in designated points of the body, generally the same points as those used in acupuncture.

In traditional Chinese medicine (TCM), yin and yang are described as complementary forces rather than antagonistic ones. They represent a fundamental duality present in both the macrocosm of the world and the microcosm of the human body.1

These forces are characterized by their opposing yet interdependent qualities:
* Yang is associated with the active, male, heaven, sun, day, heat, dry, and life.1
* Yin is associated with the passive, female, earth, moon, night, cold, moist, and death.1

The complementary nature of these forces is symbolized by the bagua and the iconic circular diagram where each side contains a portion of the other, represented by the eye of each fish. In medical practice, everything is classified as either yin or yang, and the primary goal of a physician is to restore balance between these qualities to heal disease. Practitioners may use techniques such as acupuncture to stimulate meridians and readjust the flow of qi, thereby correcting imbalances within the body's systems.12
