Work that sought to know the effectiveness of homeopathy against ticks in cattle, since there is much controversy on the subject. The idea of the research arose by the intoxication that the author suffered by cypermethrin to apply by spraying in dairy cattle and its consequences, sought alternative treatments to ticks, finding homeopathy as one of the alternatives. When becoming a student of the Course of Biological Sciences sought to investigate the real action of homeopathy, developing research work that generated the TCC (Work of Course Completion) presented to FACIP / UFU in 2011, under the guidance of Prof. Dr. Edmundo Benedetti, co guidance of Prof. Dr. Gabriela Lícia Santos Ferreira and assistance of Rafael Henrique Ribeiro de Morais, confirming the suspicion of action, but generating some doubts about the reproduction of the results in equal conditions. The book evaluated the best alternatives and corrected the inconsistencies of the TCC. Through data and information it was observed that homeopathy is effective and that there is a need to know more about this treatment option against ectoparasites, reducing the use of pesticides.
