Treatment of diabetes with traditional Chinese medicine

1. Traditional Chinese Medicine (TCM) in Diabetes Treatment

1.1 Holistic Concept and Balance Regulation

TCM emphasizes a holistic view of the human body, where all organs, meridians, and the flow of Qi (energy) and blood are interconnected. In treating diabetes (known as “Xiao Ke” or “wasting-thirst” in TCM), it is not merely focused on blood sugar levels but aims to restore balance in the body by regulating Yin-Yang and the function of internal organs. For instance, when there is Yin deficiency and excess heat (dryness and heat), TCM restores balance by nourishing Yin and clearing heat, much like maintaining harmony in an ecosystem by adjusting the water levels and temperature.
Organ Relationships: TCM believes that the lungs, stomach, and kidneys play crucial roles in the development of diabetes. The lungs control Qi and distribute body fluids. If lung function is disrupted, this can result in symptoms like excessive thirst and urination. The stomach, responsible for digestion, may become overheated, leading to increased hunger. The kidneys are vital for preserving essence, and kidney Yin deficiency often manifests as frequent, excessive urination. Treatment involves harmonizing these organ functions through methods like nourishing lung Yin, clearing stomach heat, and replenishing kidney Yin.

1.2 Syndrome Differentiation and Treatment Principles

TCM’s approach is based on Bian Zheng Lun Zhi (syndrome differentiation and treatment). Even though two patients may share the same disease (diabetes), their symptoms may vary based on different underlying patterns, requiring individualized treatment.
- Lung Heat and Fluid Injury: Symptoms include thirst, frequent urination, and dry throat. This syndrome results from heat damaging the body’s fluids. Treatment focuses on clearing heat, moistening the lungs, and generating fluids.
- Stomach Heat and Excessive Hunger: Symptoms include excessive hunger, weight loss, and constipation. This occurs due to heat in the stomach, leading to increased digestive activity and excessive consumption of nutrients. Treatment involves clearing heat and nourishing the stomach.
- Kidney Yin Deficiency: Symptoms include frequent urination, low back pain, and fatigue. This is often seen in diabetes where kidney Yin is depleted. Treatment involves replenishing Yin and strengthening kidney function.

1.3 Meridian and Qi-Blood Regulation

TCM therapies like acupuncture and tui na (massage) work by regulating the flow of Qi and blood through the body’s meridians. The meridians are likened to highways that transport Qi and blood. When they are unblocked, organs and tissues function optimally.
- Acupuncture: Key points such as the Shu Point for the pancreas can help regulate its function. For example, the San Yin Jiao point, located on the leg, is believed to harmonize the liver, spleen, and kidney meridians, improving overall health and supporting the management of diabetes.

2. Importance of Diagnosis and Examination in TCM

2.1 Comprehensive Understanding of the Condition

In TCM, an accurate diagnosis requires detailed inquiry into the patient’s medical history, including the onset and progression of symptoms such as excessive thirst, frequent urination, and hunger. Lifestyle habits like diet, alcohol consumption, and physical activity are also crucial in determining the root causes. This helps determine the severity of the condition and whether genetic factors are at play, especially if there is a family history of diabetes.

2.2 Syndrome Differentiation and Diagnosis

TCM practitioners use a comprehensive approach to diagnosis, which includes examining the patient’s face, tongue, and pulse. For instance:
- Tongue Examination: A red, dry tongue with little coating may indicate Yin deficiency, while a yellow, greasy coating suggests internal heat or dampness.
- Pulse Diagnosis: A thin pulse may point to Yin deficiency, while a rapid pulse could indicate heat. These findings help determine the exact nature of the diabetes and guide treatment.

3. Chinese Herbal Treatment for Diabetes

3.1 Synergistic Effects of Herbal Formulas

Herbal formulas in TCM are carefully crafted to work synergistically. A classic example is the Liu Wei Di Huang Wan (Six-Ingredient Rehmannia Pill), which contains herbs such as Shu Di Huang, Shan Zhu Yu, and Ze Xie. These herbs are combined to nourish Yin, clear heat, and support kidney and liver function, addressing the root causes of diabetes related to Yin deficiency and internal heat.
- Herbal Combinations: Herbs like Tian Hua Fen (Trichosanthes root) and Lu Gen (Reed rhizome) are used to clear heat, generate fluids, and alleviate thirst and frequent urination associated with lung heat patterns in diabetes.

3.2 Choosing the Right Herbs Based on Syndromes

Different patterns of diabetes require specific herbs:
- Lung Heat and Fluid Injury: Herbs like Tian Hua Fen and Lu Gen are used for their ability to clear heat and generate fluids.
- Stomach Heat and Excessive Hunger: Shi Gao (Gypsum) and Zhi Mu (Anemarrhena) are commonly used to cool the stomach and clear internal heat.
- Kidney Yin Deficiency: Goji berries and Ningxia wolfberry are used to strengthen the kidneys and replenish Yin, alleviating symptoms like lower back pain and dizziness.

3.3 The Role of Herb Processing and Dosage Forms

Chinese herbs are often processed to reduce toxicity and enhance efficacy. For instance, Shu Di Huang can be prepared in various forms such as raw or cooked to better suit the patient’s needs. Common dosage forms include:
- Decoctions: Fast absorption and effective for acute conditions.
- Pills and Powders: Convenient for long-term use and maintenance.
- Paste (Gao): Typically used for nourishing Yin and replenishing energy.

4. Differences Between TCM and Western Medicine in Diabetes Treatment

4.1 Theoretical Foundations

TCM: Views diabetes as an imbalance of internal energies, such as Yin deficiency, excess heat, and organ dysfunction. It emphasizes restoring balance through holistic approaches.
Western Medicine: Defines diabetes as a metabolic disorder, primarily caused by insulin resistance or insufficient insulin production. Treatment is focused on lowering blood sugar levels through medication.

4.2 Treatment Goals and Focus

TCM: The primary goal is not just controlling blood sugar, but also addressing the overall symptoms, improving quality of life, and preventing complications.
Western Medicine: Primarily aims to regulate blood sugar levels through insulin and oral hypoglycemic drugs, and focuses on monitoring blood glucose levels and managing complications like retinopathy, neuropathy, and kidney damage.

4.3 Treatment Approaches

TCM: Utilizes a wide range of treatments, including herbal medicine, acupuncture, dietary therapy, and exercise like Tai Chi.
Western Medicine: Relies on pharmaceuticals (insulin, oral hypoglycemics), dietary control, and exercise.

4.4 Mechanisms of Action

TCM: Herbs are used to act on multiple systems in the body, promoting overall wellness. For instance, Liu Wei Di Huang Wan helps restore Yin and regulates internal heat.
Western Medicine: Drugs target specific mechanisms, like insulin deficiency (insulin injections) or insulin resistance (metformin, sulfonylureas).

Conclusion: A Comprehensive Approach In conclusion, TCM offers a holistic and individualized approach to managing diabetes, addressing both the root causes and the symptoms, with an emphasis on balancing internal energy, regulating the organs, and enhancing overall well-being. While Western medicine focuses on managing blood sugar levels and preventing complications, combining both approaches could potentially offer more comprehensive care for diabetes patients.
