Citric Acid + Diphenhydramine + Ammonium Chloride + Menthol

This is a combination of four medicines: Citric Acid, Diphenhydramine, Ammonium Chloride and Menthol. Citric Acid is a natural substance that helps relieve mild cough. Diphenhydramine is an antiallergic which relieves cough associated with allergies by blocking a chemical messenger, histamine. Ammonium Chloride is an expectorant which works by decreasing the stickiness of mucus (phlegm) and helps in its removal from the airways. Menthol produces a cooling sensation and relieves throat irritation.
