Book excerpt: The Greening of Pharmaceutical Engineering This fourth volume in a groundbreaking new four-volume set offers new philosophies and ideas for diagnosing and treating physical disorders, with a view toward bringing the pharmaceutical industry closer to chemical, environmental, and economic sustainability. This fourth and final volume in a four-volume series on the greening of pharmaceutical engineering presents evidence for the applications of new theories advanced in the first two volumes. Similar to the Volume three, which was for mental health, this volume presents applications for the diagnosis and treatment of physical disorders. Based on the groundwork laid in the first two volumes, the authors now embark on significant, real-life scenarios that apply their theory to physical disorder treatments. In keeping with the tradition of engineering solutions, practical yet sustainable solutions are presented. The fundamental flaws of the conventional approach to medicine is well known. However, this book does not stop at unearthing criticism of western medicine. It offers hope and recommends a series of solutions for both prevention and treatment of physical ailments. Both evidence in studies and the theory behind various treatments are analyzed. Furthermore, food and energy sources are discussed in general as they both directly impact human health. Physical and emotional activities are the other tangible and intangible factors that play a role in human health are discussed. All major diseases, scientific diagnoses, and their common treatments are presented and analyzed. Recommendations for lifestyle changes that could prevent and reverse syndromes are discussed with comprehensive analysis and evidence in medicinal studies. Seasonal flus as well as Covid-19 and other recent viruses with deadly consequences are discussed and ways to manage them through diet, exercises, and meditation are presented. Treatment plans, along with food recipes for specific ailments are presented with discussion of the logic behind these remedies. Valuable as a learning tool for beginners in this area as well as a daily reference for engineers and scientists working in these areas, this is a must-have for any library.
