Cautions

  • Keep to standard doses and short courses; its cyanide-forming compounds are harmless at these amounts but add up with large doses.
  • Large doses taken over time can slow the heart rate.
  • A cough with fever, shortness of breath, or blood, or one lasting more than three weeks, needs a medical look.

Pregnancy & breastfeeding

PregnancyAvoid

Its cyanide-forming compounds, harmless at cough doses for most adults, keep wild cherry out of pregnancy; gentler cough herbs do the job.

BreastfeedingAvoid

Its cyanide-forming compounds could reach a nursing baby, so it waits until after weaning.

Folklore

Prunus serotina means the late plum, for its habit of flowering after other cherries. Settlers steeped the fruit in rum or brandy for cherry bounce, which gave it the name rum cherry, and its reddish heartwood, darkening with age, became prized American cabinet wood. Syrup of wild cherry bark sat on American pharmacy shelves as a cough remedy for well over a century.

How to grow

A fast-growing native tree for sun and well-drained soil, reaching 50 to 80 feet. Gather bark in autumn from young branches, scrape off the thin outer layer, and dry the green inner bark. Wilted cherry leaves poison livestock, so keep cut branches out of pastures.

In the wild

Woods, fencerows, and old fields across eastern North America, from Nova Scotia to Florida and west to the Great Plains, with populations south into Mexico and Central America. Birds spread its seeds, and it has become invasive in parts of Europe.
