Cough suppressant herbal drugs: A review

Abstract

A cough occurs suddenly and often repetitively which helps to clear the large breathing passages from secretions, irritants, foreign particles and microorganisms. Coughing can be due to a respiratory tract infection such as the common cold, acute bronchitis, pneumonia, pertussis, flu and smoking or health problems such as asthma, tuberculosis and lung cancer. Substantial uses of folk remedies for different medical conditions have been documented. The remedies included cinnamon, ginger, clove, cardamom, honey, lemon, garlic, onion, turmeric and licorice.
