Moderator's Note: Keep in mind that SAMe and chamomile tea are very

good remedies for your anti-anxiety medicine cabinet. These

combinations work well for those difficult days we all experience.

An Anti-Anxiety Agent in Tea?

 

I've read that L-theanine is a good anti-anxiety product. It is a

form of green tea extract. What are your thoughts on using this for

anxiety?

 

-- J. Tyler

 

L-theanine, an amino acid found in tea plants, is responsible for

the unique flavor of green tea. This compound is said to promote

relaxation and modify the stimulating effects of the caffeine

present in green tea.

 

Some research has suggested that L-theanine has calming effects. In

one study, young women were given either water, 50 mg of L-theanine,

or 200 mg of L-theanine once a week. Afterward, their brain waves

were measured. Those who received the highest dose (200 mg) produced

more alpha waves, an indication of increased relaxation, about 40

minutes after getting the L-theanine. Results of this study were

published in the June 1999 issue of Trends in Food Science &

Technology. However, more research will be needed to confirm the

findings.

 

Other studies, including animal studies, have suggested that L-

theanine has an anti-cancer effect, may enhance learning in animals,

and lowers blood pressure in hypertensive rats. But none of these

benefits have been demonstrated in humans, at least not yet.

 

As far as combating anxiety is concerned, I recommend breathing

exercises, which are the most effective and fastest-acting method I

know. Aerobic exercise is also helpful, and I would recommend

avoiding caffeine because its stimulating effects can heighten

anxiety.

 

You also might try tincture of passionflower (Passiflora incarnata),

which is mildly relaxing. The dose is one dropperful in a little

water, up to four times a day, as needed. Valerian (Valeriana

officinalis) is more powerful – use a capsule of the standardized

extract only as needed.

 

For the calming and relaxing benefits of L-theanine, I recommend

drinking green tea in moderation rather than taking a supplement. If

you find the tea too stimulating, look for a decaffeinated form.
