C
Cognitive decline & memory
Cochrane found no convincing cognitive benefit; a 2024 meta-analysis found at most a small memory-specific effect and nothing for overall cognition, attention, or executive function.

Asian ginseng is among the most famous tonic herbs, but the controlled evidence is underwhelming — at most a small memory effect, and disagreement between reviews on fatigue. It can disturb sleep and lower blood sugar, so time doses earlier and watch for interactions with diabetes drugs.
