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, the body’s qi (vital breath) flows through a network of meridians that correspond to specific organs. These meridians are linked to various phenomena, including circadian rhythms, which dictate that different organs are responsible for maintaining bodily functions at specific times of the day.1

Because of these correspondences, a headache occurring at a consistent time is interpreted as a sign that the qi of the organ associated with that time is unbalanced. For example, a headache that regularly occurs at 4 pm indicates an imbalance in the Bladder meridian, as the Bladder is in charge of the body's functions during that period.1

By identifying the specific organ and meridian involved through these temporal patterns, a practitioner can utilize the wuxing (five agents) framework to develop a targeted healing plan, which may include acupuncture, herbal medicine, or lifestyle adjustments to restore balance.1
