Overview
Flowering dogwood is a beloved native North American tree celebrated for its spectacular spring display of white or pink petal-like bracts. Beyond its ornamental beauty, dogwood bark was one of the most important medicinal plants used by Native American tribes across the eastern United States. The bark contains cornin (verbenalin), tannins, and bitter compounds that give it fever-reducing, pain-relieving, and digestive-supporting properties. During the Civil War, dogwood bark was used as a substitute for quinine when supplies were cut off, earning it the nickname "American quinine."
Traditional Use
Dogwood bark was used extensively by numerous Native American tribes including the Cherokee, Iroquois, Mohegan, and Ojibwe. The Cherokee used bark tea for fevers, headaches, and as a general tonic. The Iroquois used it for malaria-like fevers and as a stimulant. During the American Civil War (1861–1865), Confederate soldiers and physicians used dogwood bark as a substitute for quinine to treat malaria when the Union naval blockade cut off supplies of the South American bark. Traditional herbalists also used dogwood berries as a bitter tonic and the leaves topically for wounds. The bark was widely listed in early American pharmacopoeias as an official medicine.
Key Active Compounds
Cornin (Verbenalin)
An iridoid glycoside that is the primary active compound in dogwood bark. Has antipyretic (fever-reducing), analgesic, and anti-inflammatory properties, explaining its traditional use as a quinine substitute.
Tannins
Astringent polyphenols that reduce inflammation, tighten tissues, and have antimicrobial properties. Contribute to dogwood's use for digestive complaints and wound care.
Ursolic Acid
A pentacyclic triterpenoid with anti-inflammatory, antioxidant, and potential antimicrobial properties found in dogwood leaves and bark.
Bitter Glycosides
Bitter compounds that stimulate digestive secretions, improve appetite, and support liver and gallbladder function.
Evidence-Based Benefits
Fever reduction
Traditional useDogwood bark has a long history as a febrifuge (fever reducer), used by Native Americans and Civil War physicians as a quinine substitute for malarial and other fevers. The iridoid compound cornin is believed responsible for this activity.
Pain relief
Traditional useTraditional herbalists used dogwood bark tea for headaches, back pain, and general body aches. Its analgesic properties are attributed to cornin and anti-inflammatory tannins.
Digestive support
Traditional useBitter compounds in dogwood bark stimulate digestive secretions and improve appetite. Tannins help reduce diarrhea and intestinal inflammation, supporting overall digestive health.
Antimicrobial activity
Some studiesLaboratory studies have shown dogwood bark extracts exhibit antimicrobial activity against several bacterial strains, supporting its traditional use for infections and wound care.
