sage

I'd like to mention that burning sage is a ritual,
it's the intent of banishment that does most of the work.

Sage and especially culinary sage is a great herb for boosting attention.
With a combination of choline supplements,
can be used to treat, maybe even cure ADHD.

I myself have found it to be extremely effective,
I use choline-bitartrate with pantheotic acid to generate acetylcholine.
they are essential-nutrients, which are typically absent from most food.

Sage itself is an acetylcholine reuptake inhibitor,
meaning that what you start focusing on,
you continue focusing on,
so long as you use sage.

so it's actually recommend to only use sage occasionally,
since obviously you need to switch your focus,
to maintain a healthy and balanced lifestyle.
