Herbs that can help calm anxiety in some people include lemon balm, valerian root, passionflower and kava, according to LiveScience. Essential oils extracted from herbs, such as lavender, sandalwood, geranium and jasmine, can also help ease tension, notes About.com.
There is little evidence to support that herbs alone treat anxiety in the long run, and experts suggest using herbs in conjunction with other therapies. Yoga, meditation and controlled breathing are all techniques that people can try to curb stress, notes LiveScience. Massage therapy and shiatsu may help by improving sleep. The amino acid GABA appears to counteract anxiety by affecting receptors in the brain, but it requires more study, states About.com.
