There are many common effective herbal remedies for anxiety which have been used for centuries to calm down the nervous system, relieve emotional tension, as well as for reducing anxiety and improving sleep. However, there was a certain lack of scientific evidence of the fact that these herbal remedies do work well. A group of specialists at the Global Neuroscience Initiative foundation located in Los Angeles carried out a study on the effects of the most known herbal remedies and dietary supplements for nervous tension and anxiety.
The scientists analyzed 24 related scientific studies which involved more than 2,000 participants. It turned out that the combination of such amino acids as L-Iysine and L-arginine can be the best solution for combating anxiety and other mental instabilities. These compounds belong to so called “20 building blocks of proteins”, and numerous experiments on animals have shown that these amino acids are linked to improved function of those parts of our nerve system which are responsible for better resistance to anxiety, stresses and instability.
In this context, the researchers claim that extracts of kava-kava (Piper methysticum) and passionflower (Passiflora incarnata) are the most effective herbal remedies for anxiety as they have the highest content of the above mentioned amino acids. At that same time, it was a great surprise to learn that one of such powerful herbal remedies for anxiety and depression as St. John’s Wort has actually not given positive results during clinical tests. The same can be said about various natural magnesium supplements which were also considered to be effective for reducing anxiety.
One of the leaders of this research, Shaheen Lakhan, comments on the outcomes of the analysis as the following: “Our review and summary of the literature on herbal remedies and dietary supplements for anxiety should aid mental health practitioners in advising their patients and provide insight for future research in this field.” The findings of this scientific study were published in early October in the Nutrition Journal.
