Are there some natural remedies to cure laryngitis please?

Hydration. One must know the cause of the laryngitis. The term literally means inflammation of the mucosa or lining of the vocal folds. The problem can be the result of overuse or misuse of the voice, true viral infection (bacterial infection very seldom). There is no gargle for this because you would gag and aspirate it into your trachea. Drinking 4 to 6 full glasses of water a day may help. See ENT doc.
