IMUUXANTH – Redefining Immunity with Nature’s Potent Science presents an intricate synthesis of traditional botanical wisdom and modern biomedical innovation. Authored by Sir Prof. Dr. Rajdeep Dutta, the work explores the scientific foundations and therapeutic potential of Renatus IMUUXANTH, a polyherbal nutraceutical enriched with mangosteen-derived xanthones, adaptogenic herbs, and bioactive antioxidants. Through a disciplined study of phytochemistry, molecular biology, and immunology, the book reveals how natural compounds interact synergistically to restore immune equilibrium, combat oxidative stress, and strengthen cellular defense. Written in an accessible yet scholarly manner, it bridges empirical research with holistic philosophy, demonstrating that true wellness emerges from harmony between science and nature. Supported by documented findings, ethical considerations, and clinical perspectives, this text stands as both a scientific reference and a guide for health practitioners and readers who seek an evidence-based understanding of botanical therapeutics in the pursuit of sustainable immunity.
