A word from Dr. Horia Marculescu
“Throughout my career, I have observed that preventing health problems is often faster, safer, and more effective than treating them after they have developed.”
“I have noticed that modern diets, especially in the United States and other English-speaking countries, contribute to widespread digestive problems, including constipation. This observation inspired my collaboration with the author to develop a practical, evidence-based guide for relief and prevention.”
“From my experience, I advise everyone: do not wait. If you notice something awkward with your health, seek medical attention immediately. Early action makes a significant difference.”
