Traditional Chinese Medicine (TCM) is an ancient healing system that has been practiced for over two millennia. It is grounded in the concept of balancing the body’s energy (Qi), harmonizing the Yin and Yang, and supporting the Five Elements: Wood, Fire, Earth, Metal, and Water. Central to this system is the use of medicinal herbs, which are tailored to the specific needs of the patient based on their unique constitution, symptoms, and imbalances.
Herbal medicine is one of the main pillars of TCM, and its use is highly individualized. Chinese medicinal herbs are classified according to several principles, including their nature, flavor, and effect. Among these, the therapeutic effect or function of a herb is perhaps the most crucial criterion for selecting a remedy. This classification helps guide the practitioner in choosing the right herbs to restore balance, address the underlying causes of disease, and treat symptoms effectively.
In this article, we will provide a comprehensive overview of Chinese medicinal herbs based on their therapeutic effects. We will explore common herbs that are used to treat a wide range of conditions, from digestive issues and respiratory ailments to stress, inflammation, and chronic diseases. By understanding the classification based on therapeutic effects, one can gain a deeper insight into how Chinese herbs are used in the holistic treatment of the body and mind.
