TCM stands for Traditional Chinese Medicine, a complete medical system used for thousands of years. Traditional Chinese Medicine (TCM) is one of the oldest healing systems in the world. It originated in China more than 2,500 years ago and is still widely practiced today, both in China and globally. Unlike modern Western medicine, which often focuses on treating specific symptoms, TCM takes a holistic approach. It looks at the entire body and mind to restore balance and promote natural healing.

TCM includes a variety of practices such as acupuncture, herbal medicine, cupping, massage (Tui Na), and dietary therapy. One of its core ideas is the concept of "Qi" (pronounced "chee"), which refers to the vital energy that flows through the body. If this energy becomes blocked or unbalanced, illness can occur. TCM treatments aim to restore this balance and improve overall well-being.

Let’s clarify why the other options are incorrect:
- **Techno Circuit Module** sounds like a computer or electronics term, not medical.
- **Tetra Carbon Mono oxide** is not a real chemical and is unrelated to medicine.
- **Tele Communication Management** is related to networks and business technology, not health.

Modern scientific studies are still evaluating how effective TCM is for different conditions, but many people use it for managing chronic pain, stress, digestive issues, and more. It is now recognized as complementary medicine in many countries and is often used alongside modern medical treatments.

So, in medical terms, **TCM stands for Traditional Chinese Medicine**, a time-tested approach to natural healing and whole-body wellness.
