Topic Definition
- Traditional Chinese Medicine (TCM)
Traditional Chinese Medicine, often shortened to TCM, is a broad, holistic system of healing developed in China over more than two thousand years and now used in the West mainly as a complementary and alternative approach. It brings together several practices - including herbal medicine, acupuncture, massage known as tui na, movement disciplines such as qigong and tai chi, meditation, and dietary therapy - and considers the physical, nutritional, emotional, mental, and spiritual sides of a person when reaching a diagnosis. At its heart is the idea of balance between two opposing yet complementary forces, yin and yang, which together form qi, the universal life force. In this view, health flourishes when qi flows freely and in harmony, while illness arises from imbalances that block that flow, so treatment aims to restore balance and reopen the flow of qi. Because much of TCM remains unproven by rigorous research and some herbal products carry safety concerns, practitioners and health officials stress choosing a reputable provider and not using it as a substitute for necessary conventional care.
Overview
What is Traditional Chinese Medicine?
Traditional Chinese medicine (TCM) is defined as a broad range of medicine practices sharing common concepts which have been developed in China and are based on a tradition of more than 2,000 years, including various forms of herbal medicine, acupuncture, massage (Tui na), exercise (qigong), and dietary therapy. TCM is primarily used as a complementary alternative medicine approach. While TCM is regarded as an alternative medicine system in the West, in China and other Asian countries, it is practiced widely by the locals.
Medical practitioners are trained in the diagnostic and healing techniques with centuries of tradition and philosophy. Like naturopathy, TCM is holistic. It considers all aspects of the person including physical, nutritional, emotional, mental and spiritual for diagnosis.
Yin and Yang
TCM is based on the balance of opposing elements (the yin and yang) in the body, as well as their harmony with the surrounding environment.
The two main forces of yin and yang combine to form the "qi" (pronounced as "chee") or universal life force.
When qi is in harmony, health is not only enhanced but also the capacity for fulfillment, happiness, and well-being.
Disease and illness arise from imbalances of yin and yang that block the proper flow of qi.
Therapies to treat disease are aimed at restoring the balance and unblocking the flow to restore health.
Non-invasive
TCM treatments include the use of Chinese herbs, acupuncture, meditation, Chinese massage therapy, mental and physical disciplines such as Tai Chi and Qigong and nutritional therapy.
There are many criticisms of TCM as a form of healing.
Practitioners will attempt to realign the body's balance using a combination of treatments before suggesting surgery by a Western Doctor.
Most research into the effectiveness of TCM has been conducted on acupuncture. Although it has been difficult to conclusively prove the benefits of acupuncture, the results of large-scale studies are sufficiently convincing enough for FDA to consider the tradition "promising" and worthy of further study.
In addition, it has been proven that many herbs used in Chinese medicine have therapeutic benefits. For instance, ginseng and Echinacea are both powerful herbs with strong medicinal actions. More recently, there has been some acknowledgment that Chinese massage therapies do help to manipulate muscles, nerves, and tendons.
Most TCM methodologies have no research basis and remain largely unproven. Furthermore, some TCM beliefs have been mixed with Eastern mythology. For instance, tiger penis is used as an energy supplement as tigers are considered energetic animals. Whether it really helps to boost energy levels remain unsubstantiated by proper research.
Not Regulated
This makes it more important to consult a reputable and reliable TCM practitioner. However, aside from the criticisms, there is much merit in the philosophy of TCM healing. If more research can be done into TCM, then the mythology can be separated from the facts and perhaps, more people will embrace TCM more readily as a form of healing. However, Chinese herbal remedies are now being used to treat mental disorders, such as depression, in the Western World.
Chinese Medicine Facts and Statistics
- Herbal medicines used in TCM are sometimes marketed in the United States as dietary supplements.
- Do not use TCM to replace effective conventional care or as a reason to postpone seeing a health care provider about a medical problem.
- There have been reports of Chinese herbal products being contaminated with drugs, toxins, or heavy metals or not containing the listed ingredients.
- For most conditions, there is not enough rigorous scientific evidence to know whether TCM methods work for the conditions for which they are used.
- Some herbs used in Chinese medicine can interact with drugs, have serious side effects, or be unsafe for people with certain medical conditions.
- Harmony between two opposing yet complementary forces, called yin and yang, supports health, and disease results from an imbalance between these forces.
- The FDA regulates acupuncture needles as medical devices and requires that the needles be sterile, nontoxic, and labeled for single use by qualified practitioners only.
- Acupuncture is generally considered safe when performed by an experienced practitioner using sterile needles. Improperly performed acupuncture can cause potentially serious side effects.
- An assessment of the research found that 41 of 70 systematic reviews of the scientific evidence (including 19 of 26 reviews on acupuncture for a variety of conditions and 22 of 42 reviews on Chinese herbal medicine) were unable to reach conclusions about whether the technique worked for the condition under investigation because there was not enough good-quality evidence.
