Evidence indicates that certain herbs can have powerful anti-anxiety effects.  Herbal supplements for anxiety are considered safer than prescription medications and are less lively to result in addiction or long term dependence.  However bear in mind that herbal supplements are not comprehensively evaluated by the FDA and some may not be effective.  It is always worth sticking to products that contain specific herbs whose effects  have been widely researched.  The following are generally considered to have potent properties:

The effects of Valeriana officialis (Valerian root) to reduce nervous tension has been backed up by clinical trials.  It is relatively quick acting and also appears to be effective for insomnia.

L-theanine is considered to have strong anti-anxiety properties and is not habit forming.  It is an amino acid derived from green tea.

There is growing evidence to support the claim that passion flower extract containing vitexin is effective for anxiety conditions.  It is often used in combination with valerian.

Kava, generally taken as a sedative beverage, has long been known for its calming properties but concerns have arisen over its potential for liver damage.

Although not backed up by clinical trials many anxiety sufferers have reported positive results after taking St John’s wort.

Although not strictly speaking a herbal supplement, vitamin C and vitamin B both help contribute to a healthy nervous system.

It is sensible to speak with your doctor before taking an anxiety supplements.  This is vital if you are taking medical anti-depression drugs. As mentioned at the outset, herbal supplements are not closely regulated by the FDA.  They should also only be taken as part of an holistic approach for stress management.  It’s no point taking an anxiety supplement if you also do not ensure that you are getting adequate rest, exercising regularly or eating well.  It also makes sense to consider emotional and spiritual factors that could be effecting your well-being.
