Questions people ask
Can kitchen sage reproduce the memory result?
The trial used a standardized extract, not a culinary serving, so its finding does not establish an equivalent food amount. 2
Are hot flashes and excessive sweating the same evidence?
No. Small menopause studies and EMA’s traditional-use sweating indication are separate bodies of evidence. 1 3
Is more sage better for memory?
The small dose-comparison trial favored 333 mg on its main memory measure; it does not support assuming that larger amounts work better. 2
