Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Butternut (Juglans cinerea), also known as white walnut, has a history of use in traditional herbal medicine, particularly among Native American and early North American settler practices. It has primarily been used as a mild laxative, but there are some historical references to its use in treating respiratory conditions, including dry coughs. The bark and inner bark were sometimes made into teas or syrups purported to soothe coughs and aid in clearing congestion.

However, the evidence supporting butternut's efficacy for dry cough is limited to anecdotal and traditional uses. There are no well-designed clinical trials or substantial scientific literature validating its use specifically for dry cough. Modern herbal references may occasionally list butternut among plants used for respiratory complaints, but this is based on historical precedent rather than robust scientific data. The active compounds in butternut, such as juglone, are better known for their laxative and purgative effects rather than direct antitussive (cough-suppressing) properties.

In summary, the use of butternut for dry cough is justified by traditional use, with little to no scientific validation. Evidence is weak and based mainly on historical practices rather than modern research.
