Traditional Japanese Medicine: Kampo

I. Traditional Views of Disease

Traditional Japanese medicine does not distinguish between mind and body, viewing them as an inseparable entity.

• Balance of Substances: Illness is believed to arise when the three main substances of life are disturbed: Ki (energy/vital force), Ketsu (blood), and Sui (body fluid).
• Concepts of Imbalance: Ki-Kyo (emptiness of ki) or Ki-Utsu (stagnation of ki); Oketsu (blood stagnation/stasis); Sui-Doku (fluid toxicity/retention).
• The Sho (Pattern Diagnosis): Rather than focusing on a single disease name, Kampo focuses on the Sho, a holistic pattern diagnosis based on the patient's current symptoms, physical constitution (taishitsu), and mental state.
• Pre-symptomatic Care (Mibyo): A critical concept in Japanese medicine is treating Mibyo, or "not yet diseased" states—functional disorders and imbalances that haven't yet developed into full, measurable illnesses.
• Spirituality & Nature: Historically, disease was viewed as punishment by gods (tatari), or possession by spirits. This fostered a belief in purification, ritual, and coexistence with, rather than destruction of, pathogens.

II. Traditional Treatments and Modalities

Kampo therapies focus on stimulating the body's natural healing capacity through gentle, holistic methods.

• Kampo (Herbal Medicine): This involves prescribing complex, multi-herb formulations. Unlike Traditional Chinese Medicine (TCM), which often adjusts single herbs, Kampo utilizes fixed formulas designed for specific Sho.
• Acupuncture: Very thin needles are inserted into specific meridian points to balance Ki. Japanese acupuncture often uses a Shinkan (guide tube), allowing for painless insertion.
• Moxibustion (Okyu): A form of heat therapy where dried mugwort (yomogi) is burned near the skin to stimulate blood flow and energy.
• Amma (Massage): A traditional massage technique designed to balance the flow of Ki and treat ailments.
• Shiatsu: A modern development of traditional Japanese therapeutic touch, using finger and palm pressure to correct internal imbalances.
• Dietary and Lifestyle Therapy: Foods are classified by their cooling, warming, or neutral properties, following the concept of "medicinal meals" (yakuzen).

III. Modern Healthcare and Integration (Tougouiryou)

Japan has a unique medical system where traditional Kampo is fully integrated with Western biomedicine.

• Insurance Coverage: Currently, 147–148 Kampo herbal formulas, along with acupuncture, are covered by the national health insurance system.
• Integration with Western Medicine: Over 80% of Japanese physicians prescribe Kampo medicine, often using it to treat chronic diseases and functional disorders.
• Modernizing Tradition: Modern Kampo is subject to scientific validation, with thousands of randomized controlled trials (RCTs) performed to study its efficacy.
• Pre-packaged Extracts: Standardized, high-quality, pre-packaged granules are commonly prescribed, enabling precise dosing.
• Specific Usage: Kampo is heavily used for digestive diseases, psychosomatic disorders, and as supportive care in cancer treatment.
