Yes, didn't want to go much into details because it's not my field either, since I see some of us here like science, I'll share some more of what I found:
What I'm interested in is applications of plants to some psychiatric conditions, specially bipolar disorder, which is one of the toughest to cure.
Pills given to patients have many side effects which you may or may not want to tolerate, but I came to an idea that there must be a solution in plant world.
So, instead of eating a bunch of plants or cutting up mice, I did some research prior.
Since I'm not as scientific as you, I went by simple logic and lots of googling:
1. Seems like bipolars have low GABA levels:
"The distribution of pGABA in bipolar patients, whether manic or depressed, was similar to that in symptomatic unipolar depression, with 30% to 40% having pGABA levels lower than the control range. These data indicate that low pGABA is not specific to the depressed state, as it is also found in the manic phase of bipolar disorder. Low pGABA may represent a shared biologic correlate between bipolar and unipolar illness."

"These results suggest that one common mechanism of action of lithium and carbamazepine is mediated by GABAB receptors and that GABA is involved in the pathophysiology of affective disorders."
http://www.sciencedirect.com/science/article/pii/00142999899068703. S.baicalensis has GABA agonists? Interesting!
"Baicalein and Wogonin are both potent GABAA agonists, and can activate this receptor. This is thought to mediate some of the depressant and anxiolytic effects of scutellaria baicalensis"
Oh wait, it has GABA antagonists too? No way.
"Oroxylin A is a relatively effective GABAA antagonist at the benzodiazepine binding site and has been confirmed to be active following oral ingestion, its properties oppose that of baicalein and wogonin"
https://examine.com/supplements/scutellaria-baicalensis/Well, I researched lithium, which is readily given to bipolar patients all over the world, and it's not as studied in this field of science; also has many negative side effects and requires extraction from limited resources. While this plant works, grows easily, and as you can see it IS known to science for some time. Maybe they just take too long to make it into a pill. And Im'ma just take the roots, boil it and drink the sh* out of it, see what happens
Peace
