His treatments combined up to 12 types of natural medicine — including acupuncture, herbal medicine, aromatherapy, food medicine, and more — tailored to each individual patient.

"Each person is different, every body's needs are different, each illness is caused by different reasons, so the prescriptions vary with every patient."

What people ask about TCM

What is Traditional Chinese Medicine?

Traditional Chinese Medicine (TCM) is a 4,000-year-old system of natural healing that includes acupuncture, herbal medicine, food therapy, cupping, tuina (therapeutic bodywork), and qigong. It views the body as an interconnected whole — physical, emotional, and energetic — and treats the root cause of illness rather than only its symptoms.

Does acupuncture actually work?

Yes — and it's now backed by significant Western clinical research. The World Health Organization, the National Institutes of Health, and major academic medical centers including the Mayo Clinic and Johns Hopkins recognize acupuncture's effectiveness for chronic pain, migraines, nausea, anxiety, infertility, insomnia, and dozens of other conditions. Many U.S. health insurance plans now cover it.

Who was Dr. Timothy Yeh?

Dr. Timothy Yeh (Ph.D., O.M.D., M.D.) was the President of the Yeh Center of Natural Medicine in Upland, California, and a recognized pioneer of natural medicine in the United States. He treated over 500,000 patients across five decades, was named 2004 Physician of the Year by the Physicians' Advisory Board, and developed the Five Step Model of Systematic Natural Medicine. He was trained under descendants of royal physicians from the Qin and Ching Dynasties.

What does TCM mean by "yin and yang"?

Yin and yang is TCM's framework for noticing imbalance in the body. Yin represents cooling, slowing, restorative qualities; yang represents warming, activating, expanding qualities. Health is the balance between them. Symptoms like persistent cold hands, fatigue, and quiet exhaustion suggest yang deficiency; restless heat, irritability, and 3 AM wake-ups suggest yin deficiency.

How do I find a qualified TCM practitioner near me?

Look for a practitioner who is licensed in your state and certified by the National Certification Commission for Acupuncture and Oriental Medicine (NCCAOM). Most U.S. states require licensure to practice acupuncture. We're building a curated network of trusted practitioners — see our directory →

What is the TCM body clock?

The TCM body clock is the observation that each two-hour window of the 24-hour day corresponds to a specific organ meridian's peak activity. 1–3 AM is the liver, 3–5 AM is the lung, 5–7 AM is the large intestine, and so on. Practitioners use the clock to interpret symptoms that occur consistently at certain times — like waking at 3 AM. Read the full article →
