Anxiety Disorders/anxiety


I seem to have problem with anxiety and feeling uncomfortable during the day. It seems that I can drink tea (especially black tea) to calm down but I've heard from some sources that this would only make the problem worse. What do you think?

I too have read about contradictory information about black tea. On the one hand black tea increase adrenaline secretion on the other hand the L-Theanine in black tea is a calming agent.

To quote:
"L-theanine (N-ethyl-L-glutamine) or theanine is a major amino acid uniquely found in green tea. L-theanine has been historically reported as a relaxing agent, prompting scientific research on its pharmacology. Animal neurochemistry studies suggest that L-theanine increases brain serotonin, dopamine, GABA levels and has micromolar affinities for AMPA, Kainate and NMDA receptors. In addition has been shown to exert neuroprotective effects in animal models possibly through its antagonistic effects on group 1 metabotrophic glutamate receptors. Behavioural studies in animals suggest improvement in learning and memory. Overall, L-theanine displays a neuropharmacology suggestive of a possible neuroprotective and cognitive enhancing agent and warrants further investigation in animals and humans."
