Clinical definition based on the clinical symptoms of Rhinosinusitis. With these symptoms, we performed a repertorization of symptoms and studied the drugs found Nux vômica and Kali Bichromicum. Based on these results, we expanded our review in which we found studies relating the improvement of sinus symptoms with the use of Kali bichromicum. We also review studies that use homeopathy in the treatment of Rhinosinusitis.
