The respiratory system is a biological system that introduces respiratory gases to the interior and performs gas exchange. Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous external environment and the blood. Respiratory infections most commonly occur in the winter season when cold, wet, damp weather affect the functioning of the lungs and other respiratory organs. Respiratory diseases contain coughing, asthma, pneumonia, etc.
Many herbal extract are effective preventatives or cures of these diseases, such as Quercetin and Polydatin, etc. Fortunately, therapeutic herbal treatments can have a profound influence on respiratory afflictions. Herbs can be used to allay coughing and sore throat, and may be useful for respiratory infections and asthma. Plants that have expectorant, demulcent, antitussive, and antimicrobial effects are widely used in academia and industry such as pharmacy, health care, food industry etc. Expectorant herbs thin and expel mucus that can congest the air passages. Demulcent herbs contain mucilage which soothes dry, irritated tissues as a specific treatment for a sore throat or a dry cough. Antitussive agents reduce respiratory spasms and are most beneficial for coughs which have a dry, irritated character and for the treatment and maintenance of asthmatic conditions. Antimicrobial agents are important to include in a respiratory formula to address the source of the infection.
