Used in homeopathy to relieve breathlessness, especially in cases of chronic asthma, emphysema, and bronchitis. it helps improve oxygen uptake in the lungs, making it easier to breathe in conditions with obstructed or shallow respiration. often called the "digitalis of the lungs," it is also used to reduce cyanosis (bluish discoloration due to lack of oxygen) and to relieve tightness in the chest. it is particularly beneficial for individuals with labored breathing not due to heart weakness.
