Bronkill capsules are an herbal supplement that can provide natural relief from asthma symptoms. Asthma causes inflammation in the lungs and airways, making breathing difficult. Bronkill contains herbs that strengthen the lungs and make them less susceptible to asthma attacks. It works by reducing phlegm and inflammation in the lungs to improve breathing and prevent future asthma symptoms like wheezing, coughing, and shortness of breath. Common signs of asthma include shortness of breath, chest tightness, trouble sleeping, and wheezing sounds when exhaling.
