What are the effects of the herb salvia on the brain?
Brain-imaging studies performed in animals at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory provide researchers with clues about why an increasingly popular recreational drug that causes hallucinations and motor-function impairment in humans is abused. Using trace amounts of Salvia divinorum – also known as “salvia,” a Mexican mint plant that can be smoked in the form of dried leaves or serum – Brookhaven scientists found that the drug’s behavior in the brains of primates mimics the extremely fast and brief “high” observed in humans.
