The detoxification system is a complex network comprised of various organs, including the liver, kidneys, skin, gastrointestinal tract, and lymphatic system. It plays a vital role in maintaining health by processing and eliminating toxins from the body. The functional medicine approach to detoxification focuses on addressing the root cause by considering individual characteristics. This personalized approach can help maintain a healthy detoxification system and promote overall health through strategies like normalizing liver function, implementing a nutritional approach, utilizing intestinal microbiota, and managing sleep and stress.
