Bacopa monnieri improves language, learning and memory.
Based on single pilot study (n=11) showing 46% pain reduction. Very limited evidence with small sample size. GI discomfort may occur at higher doses. Individual variation noted in study.
Based on meta-analysis showing significant HAM-A score reduction (p=0.0007) and RCT evidence at 125mg dose. High heterogeneity (I2=98%) in pooled analysis suggests variable response. Extract standardization affects bioavailability.
