There are lots of articles which hail and glorify jiaogulan tea in every aspect and say it is effective for anxiety disorders. I cannot find any resource that explains the mechanism it works on brain. Is it gabaergic? How does it exactly work on brain? They only say adaptogen which doesn't say anything. Does this thing cause tolerance and therefore dependence? Does it cause withdrawal aftef extended use? If not than how is it possible? Brain gets adjusted to anything, how can it be helping for a long time? And does it? Or benefits are short lived. Hundreads of pages online never detail this much.
