Scientists discovered a compound in the leaves of a common shrub, the American beautyberry, that boosts an antibiotic’s activity against antibiotic-resistant staph bacteria. Laboratory experiments showed that the plant compound works in combination with oxacillin to knock down the resistance to the drug of methicillin-resistant Staphylococcus aureus, or MRSA.
The American Chemical Society’s Infectious Diseases published the finding, led by scientists at Emory University and the University of Notre Dame.
The American beautyberry, or Callicarpa americana, is native to the southern United States. Prolific in the wild, the shrub is also popular in ornamental landscaping. It’s known for showy clusters of bright purple berries that begin to ripen in the summer and are an important food source for many species of birds.
