In addition to the usual diseases caused by viruses and bacteria, a person is also susceptible to attacks by parasites, which, gradually undermining health, live in the human body - and not only in the intestines. They can successfully multiply and exist in the liver, lungs, genitourinary and lymphatic systems, blood vessels, blood, brain, etc. Parasites act slowly and insidiously, causing difficult-to-diagnose diseases that torment their victims for years and decades. Today, the theory of the parasitic origin of the most terrible disease - cancerous tumors - is being seriously considered. Perhaps this book will help you by outlining ways to solve long-standing health problems.
