Memory/Focus enhancing Herbs/Supplements

Jedi rely on focus.
Jedi thrive on learning.
Lets name some nootropic supplements to help others out.

Piracetam- The first memory enhancing substance, works through ampa receptors.
Ginkgo Biloboa- Energy and focus enhancer,variety of unknown mechanisms.
Uridine- Increases Nerve growth factor.
Forskolin & Artichoke- Increases neuronal memory mechanisms.

Do the memory enhancers deal with Working memory or Long-term memory? Encoding or Storage?

Piracetam and gingko biloboa work with working memory.
Uridine and forkskolin & artichoke work with long term memory.

Thanks! That's really good to know.
