Vertigo, from the perspective of Traditional Chinese Medicine (TCM), consists of two different discomfort in the head, called Xuan Yun (眩晕). Xuan is defined as experiencing giddiness or a blackout all of sudden, whereas Yun is a feeling that you or your environment is moving or spinning. This problem is commonly seen due to high blood pressure, arteriosclerosis, anaemia, neurosis, labyrinth disease, cervical spondylosis, brain tumour, amongst others. Severe vertigo may be caused by Ménière’s disease, a condition that affects the inner ear, that can cause hearing loss, tinnitus and a feeling of fullness or congestion in the ear.
In TCM, the earliest mention of the term vertigo（眩冒）was in the ancient medical text, Huangdi Neijing, which stated that “the causes of vertigo is most likely related to the liver”. It is difficult to link a specific anatomical part to the term Liver (肝) as defined by the Chinese physician, but rather it refers to a functional complex, which may include the functional system of the liver as well as other parts surrounding it.
The onset of vertigo can be due to factors such as a fluctuation in emotion (情志不遂), ageing and deficiencies in Kidney Yin (年高肾亏), after a serious illness (病后体虚), uncontrolled diet (饮食不节) and blood stasis due to injury (跌仆损伤，瘀血内阻). Even though the root causes of vertigo may be due to the aforementioned reasons, from the TCM point of view, pathological changes are divided into two: the excess, due to pathogenic wind or fire, phlegm or blood stasis disturbing the brain; and the deficiency, which is associated with the asthenia of Qi and blood, lack of Liver or Kidney Yin to nourish the brain.
Common treatments for vertigo are acupuncture and prescription of Chinese herbal medicine. Depending on the symptoms of the vertigo shown, different acupuncture points and Chinese herbal medicine will be prescribed (see below). Different acupuncture methods can also be applied to treat vertigo. These include body, ear and scalp acupunctures.
One should consider the internal and external factors in order to prevent vertigo. Physical exercises, ensuring emotional wellbeing, optimum amount of daily rest, and a healthy diet are all important.
