Active Ingredient	Uses based on scientific evidence	Grade*
black tea (camellia sinensis)	limited, low-quality research reports that the use of black tea may improve cognition and sense of alertness. black tea contains caffeine, which is a stimulant.	c
ginkgo (ginkgo biloba l.)	the results of one study investigating the effect of ginkgo biloba on post-prandial mental alertness are unclear. ginkgo may benefit some but not all endpoints. further clinical trials are required before recommendations can be made.	d
ginseng (american ginseng, asian ginseng, chinese ginseng, korean red ginseng, panax ginseng: panax spp. including p. ginseng c.c. meyer and p. quinquefolius l., excluding eleutherococcus senticosus)	several studies report that ginseng may modestly improve thinking or learning. benefits have been seen both in healthy young people and in older ill patients. effects have also been reported with a combination of ginseng and ginkgo biloba . however, some mixed results have also been reported. therefore, even though most available evidence supports this use of ginseng, better research is needed before a strong recommendation can be made.	c
green tea (camellia sinensis)	several preliminary studies have examined the effects of caffeine, tea, or coffee use on short and long-term memory and cognition. it remains unclear if tea is beneficial for this use. limited, low-quality research reports that the use of green tea may improve cognition and sense of alertness. green tea contains caffeine, which is a stimulant.	c
