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.
