Beautyberry leaf extract boosts drug's activity antibiotic-resistant staph bacteria

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.
