What is Chinese Herbal Medicine
Chinese herbal medicine is part of a larger healing system called traditional Chinese medicine (TCM), which also includes acupuncture, massage dietary advice and exercise.
The underlying principles of TCM are very different from traditional Western notions about health, illness and the workings of the body. Chinese herbs are prescribed to normalise imbalanced energy, or Qi (pronounced ‘chee’), that runs through invisible meridians in the body. Whether or not the philosophy is believed, studies have shown Chinese herbal medicines to be successful in treating a range of disorders, particularly gynaecological and gastrointestinal disorders.
Yin and Yang
The ancient Chinese proposed that every living thing is sustained by a balance of two opposing forces of energy, called Yin and Yang. Together, they make up the life essence, or Qi - a type of energy that flows through the body via invisible channels called meridians. Half of certain organs and meridians are governed by Yin and the other half by Yang. When Yin and Yang are out of balance in the body, this causes a blockage of Qi and a subsequent illness. Yin and Yang imbalances can be caused by stress, pollution, poor diet, emotional upsets or infection. For diagnostic purposes, Yin and Yang are further subdivided into interior and exterior, hot and cold, deficiency and excess.
The Five Elements
The TCM philosophy proposes that everything including organs of the body - is composed of the five elements: fire, earth, metal, water and wood. The herbs are similarly classified into the five tastes, sweet, salty, bitter, pungent and sour, which correspond to the five elements. For example, since the skin is a metal element Yang organ, it would be treated with a pungent herb.
Herbs Used in Chinese Medicine
Chinese herbal medicines are mainly plant based, but some preparations include minerals or animal products. They can be packaged as powders, pastes, lotions or tablets, depending on the herb and its intended use. Different herbs have different properties and can balance particular parts of the body. Prescribing a particular herb or concoction of herbs means the practitioner’s diagnosis has to take into account the state of the patient’s Yin and Yang, and the elements that are governing the affected organs.
