Prunus serotina (Wild Cherry) is used for which effect?

• A. Antitussive
• B. Bronchodilator
• C. Expectorant
• D. Decongestant

Answer: (A)

Wild cherry bark is traditionally used as an antitussive, meaning it helps suppress a cough. In herbal practice, its soothing, slight sedative effect on the airway mucus membranes can calm an irritated cough reflex, making it a common ingredient in cough remedies for dry or irritating coughs. It’s not typically used to loosen or expel mucus (that would be an expectorant), nor to open airways (a bronchodilator) or reduce nasal congestion (a decongestant).

So the best fit is the cough-suppressing effect. A note on safety: the plant contains cyanogenic glycosides in seeds, so preparations are used in proper, limited amounts.
