Asthma occurs when the airways of the lungs become narrow and it makes difficulty in breathing. This narrowing is usually caused by inflammation, which makes the airways swell and may cause the cells of the airway to make excess mucus.
The effects of Asthma become more sever during pollution days or due to allergens present in the air. As per the Ayurveda Bronchial Asthma is Vatakaphaja disease, it begins in the stomach, progresses to the lungs and bronchi. Hence the aim of treatment is to move the excess Kapha back to stomach and then eliminate it.
