title: Huperzine-A capsules enhance memory and learning performance in 34 pairs of matched adolescent students.
abstract: OBJECTIVE
  To study the efficacy of huperzine-A capsules (Hup) on memory and learning performance of adolescent students.
  
  
  METHODS
  Using double-blind and matched pair method, 34 pairs of junior middle school students complaining of memory inadequacy were divided into two groups by normal psychological health inventory (PHI), similar memory quotient (MQ), same sex and class. The Hup group was administrated orally 2 capsules of Hup (each contains Hup 50 micrograms) b.i.d., and the placebo group was given 2 capsules of placebo (starch and lactose inside) b.i.d. for 4 wk.
  
  
  RESULTS
  At the end of trial, the Hup group's MQ (115 +/- 6) was more than that of the placebo group (104 +/- 9, P < 0.01), and the scores of Chinese language lesson in the Hup group were elevated markedly too.
  
  
  CONCLUSIONS
  The Hup capsules enhance the memory and learning performance of adolescent students.
