Bayberry is an evergreen shrub native to the southeastern United States, traditionally used by Native American peoples for digestive issues, fevers, sore throat, and as a general astringent remedy. Its waxy berries gave rise to a genuinely distinct historical use entirely separate from medicine — colonial settlers rendered the wax into candles, giving the plant its common names Wax Myrtle and Candleberry.
Bayberry bark, rich in tannins and the flavonoid myricetin, became a staple of 19th-century American herbal medicine, prized for its astringent effect on tissues — a traditional application that modern research has only begun to test directly.
Bayberry has one genuinely notable recent human trial: a placebo-controlled study in young adults with early-stage fatty liver disease found bayberry juice significantly reduced two key inflammatory markers along with signs of oxidative protein damage over four weeks — a real, positive human finding for a specific liver-related application.
Beyond this one trial, the broader picture is honestly thin. An independent evidence source states plainly that "human data on the therapeutic use of bayberry for any condition are currently lacking." A genuinely important safety note, worth flagging given the one positive trial concerned liver inflammation: prolonged or excessive oral use of bayberry has itself been associated with potential liver toxicity — a real tension worth being aware of. Given one specific positive trial but an authoritative source stating data is otherwise lacking, "Limited" is the accurate, appropriately cautious rating.
Bark and leaves dried and prepared as tea or tincture; traditionally used as a gargle for sore throat or taken for digestive complaints.
