1. Traditional Chinese Medicine (TCM)
Property & Function: TCM treats the gut microbiome as part of the "Spleen and Stomach" system, responsible for converting food into Qi (energy) and Blood. It emphasizes "holism"—the interaction between the human body, its commensal bacteria, and the environment. A healthy gut is one where Qi flows freely, and "dampness" or "phlegm" (metabolic waste/dysbiosis) is low.
Diseases: TCM links "Spleen Qi Deficiency" (weakened digestive function/low bacterial diversity) to obesity, chronic fatigue, anxiety, depression, and cognitive fog (clouded mind).
2. Ayurvedic Tradition
Property & Function: Ayurveda considers digestion (Agni—digestive fire) the cornerstone of health. The microbiome is responsible for producing Ojas, the finest byproduct of healthy digestion, which strengthens immunity, mental clarity, and longevity.
Diseases: The root of disease is Ama—undigested, toxic, sticky metabolic waste resulting from low Agni. This aligns with modern concepts of leaky gut, dysbiosis, and inflammation. Imbalances can cause IBS, constipation, chronic diarrhea, and systemic metabolic syndromes.
3. African Traditional Medicine
Property & Function: Focuses heavily on the consumption of fermented indigenous foods, which act as probiotics and bio-therapeutics. The microbiome is seen as a crucial component in maintaining digestive homeostasis and enhancing the immune system through the consumption of fibers and nutrient-dense traditional foods.
Diseases: Dysbiosis is addressed through these foods to treat digestive disorders, boost nutrient absorption, and improve immune response, with growing focus on using these methods to combat non-communicable diseases (like diabetes) and, recently, COVID-19 severity.
4. Middle Eastern Traditional Medicine
Property & Function: Often integrated with Unani-Tibb (Graeco-Arab medicine), it views gut health through the balance of humors. Emphasis is on "digestive heat" (similar to Agni) and strengthening the fuaad (gut) through the use of herbs and fermented ingredients to clear toxins.
Diseases: Chronic GI disorders, metabolic issues, and immune imbalances arising from sedentary lifestyle or poor diet.
5. American Indigenous Traditions
Property & Function: Focuses on a synergistic relationship with the environment and food. Microbiome health is nurtured through diet, often rich in local, fibrous plants, medicinal herbs, and natural fermented foods that foster harmony within the body, treating it as a "superorganism".
Diseases: Often associated with the loss of indigenous microbes through adoption of modern lifestyles (high-fat/sugar diets), leading to metabolic and autoimmune diseases.
