Chinese Herbal Medicine and TCM Classification

Traditional Chinese Medicine (TCM) is a holistic and complex treatment system that includes several treatment modalities to promote healing and wellness [11]1. Chinese herbal medicine is a part of TCM and is based on the use of natural substances, mainly plant-related, to restore energy balance and promote healing [33]3. The herbs are classified according to their flavours (sour, salty, sweet, bitter, and pungent) and properties, which are further divided into taste, thermal property, direction, and channel affiliations [11]1, 22]2.

The classification of Chinese herbs is based on the "Yin-Yang" theory, which is the basis of TCM. Yin and Yang are opposing forces of energy that should be in balance for optimal well-ness. Herbs are prescribed to restore this balance and can act on the body as powerfully as pharmaceutical drugs [33]3. The herbs are classified into the five tastes, which are sweet, salty, bitter, pungent, and sour [33]3.

The properties of Chinese herbs are also classified according to their "Yin-Yang" nature, i.e., Yin, neutral, and Yang herbs, according to TCM [44]4. The "Yin-Yang" property of Chinese medicinal herbs is believed to be based on their chemical compositions, which provide a new perspective for further illustration [44]4.

Chinese herbal medicine recognizes that an optimal therapeutic effect is achieved through identifying and prescribing herbs based on their characteristics, which include taste, thermal property, direction, and channel affiliations [11]1. Single herbs may be prescribed in the event of a clear diagnosis without additional complexities, but most pathological conditions are aggregations of imbalances, and a more complex treatment may be prescribed [11]1.

The herbs used in Chinese medicine are mainly plant-related, 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 [33]3. Different herbs have different properties and can balance particular parts of the body [33]3.

Chinese herbal medicine is part of a larger healing system called TCM, which also includes acupuncture [33]3.
