I suppose you were probably joking that you have forgotten what it is.
Nevertheless, answering the serious question, comfrey has various
traditional usages (and not much use for any of them) but memory is not
one of them. Moreover it is unlikely that taking any substance,
man-made or botanical, will be of any specific use for improving your
memory.

Actually, I understand that caffein, and ginko (not together) have shown
promise, at least with short term memory.

Use ginkgo biloba if your memory loss is due to age-related issues.
Simply forgetting where you ate dinner last night will probably be
better treated by other herbs. However, if documented memory loss is due
to age, ginkgo is the best herb to use.
