Asthma is a condition in which the air passages become inflamed, resulting in the narrowing of the airways that transfer oxygen to the lungs.
When a normal person takes a breath, the band of muscles - called bronchi or bronchioles -around these airways are relaxed, and air can easily move around the body.
But a person affected by asthma has red, inflamed bronchial tubes, causing these passages to become constricted and the individual to struggle to breathe through them.
CBD is well known for relieving inflammation, and when taken orally or inhaled it helps to relax and open up the bronchioles, dilating the respiratory passage and making it easier to breathe.
Studies have shown that this anti-inflammatory, anti-spasmodic response helps to treat the symptoms of asthma and make it easier to breathe.
