I started taking ginkgo because my bud smoking was doing mean things to my short term memory (actually I’m stoned now). 2 capsules a day. a month later I’m able to recall childhood memories in way more detail(I’m 20), concentration has definitely improved and I feel I’m using a broader vocabulary in normal daily conversations (acid was the one who made me read the dictionary in the first place). Short term memory is still fucked, especially when I forget to take ginkgo for a day or maybe my keys just like playing hide and seek.
