Study finds evidence to back herbal remedies

TWO herbal remedies used for centuries to alleviate anxiety have won the backing of scientists.

Researchers found "strong evidence" that both passionflower extract and kava combat anxiety disorders.

Pooled results from an analysis of 24 studies involving more than 2,000 participants also indicated that combinations of the amino acids L-lysine and L-arginine may be useful anxiety remedies.

But the herbal medicine St John's Wort, which is commonly taken to relieve depression, and magnesium supplements were not found to be effective.

The findings were published today in the Nutrition Journal.

Passionflower has a long history of treating anxiety in folklore all over the world. It treats restlessness and nervousness. However, it is unclear which of the thousands of chemicals in the plant explain its effects.

Kava is a drink prepared from the plant Piper methysticum to also treat anxiety.
