Erratum to: The chronic effects of an extract of Bacopa monniera (Brahmi) on cognitive function in healthy human subjects (vol 156, pg 481, 2001)

The authors would like to bring to the attention of the readers two important methodological mistakes/omissions made in this paper as originally published. We stated that: "Each capsule contained 150 mg B. monniera extract (20:1) equivalent to 3 g dried herb." This is incorrect and should read: "Each capsule contained 160 mg B. monniera extract equivalent to 4 g dried herb." We would also like to clarify that the concentration of extraction solvent in manufacturing Keenmind (CDRI08) was 75 % ethanol. We apologize for these errors. We relied on the information supplied to us by the manufacturers, which was incorrect
