Should I take Kava extract for my anxiety?

Generalized anxiety is a common medical ailment in North American society. This medical disorder can present with a range of symptoms. In severe cases, anxiety can be disabling and affect one’s life style. For decades, the only treatment available for generalized anxiety has been pharmaceutical drugs. There are many drugs which have been used to treat anxiety, and while effective, drugs also possess adverse side effects. For this reason, many patients have been turning to alternative health care for managing their anxiety.

One of the products frequently consumed by individuals with anxiety is kava. Kava is easily available in most health food stores and estimates indicate that sell of this herbal extract brings in hundred of millions of dollars. The question remains, "is Kava effective for treating anxiety?"

Cochrane reviews recently published the results of twelve trials that looked at kava versus placebo in the management of anxiety. The study looked at the oral preparation of kava extract. Out of the 12 studies, results of 7 studies were compared and assessed using stringent clinical criteria.

Compared with a sugar pill, kava extract was more effective for symptomatic relief of anxiety. Even though the number of patients assessed was small, the results did show a mild to moderate improvement in patients treated with kava. Further, kava was also found to be safe and relatively free of side effects when treatment was conducted anywhere from 1-24 weeks.

So what does mean for the consumer who has anxiety?

For once at least, some herb appears to be effective in treating a medical ailment. Kava has been shown to be safe for short-term usage and it does relieve anxiety. What is not known so far is whether kava works in all people with anxiety. Kava is a lot cheaper than all currently available pharmaceutical medications. For the individual with anxiety, one should perhaps try out kava for at least 4-6 weeks to determine if it works. If kava makes no difference after a 2-month period, it is not going to work at all. Before doubling up on the dose, perhaps one should discuss this situation with a health care professional. In the end when all else fails, one has no choice but to revert back to the pharmaceutical drugs.

Herbs and Anxiety

Anxiety can be a troublesome disorder often associated with both physiological and psychological changes in the body. The emotional and behavioural symptoms can be very unpleasant and typically include apprehension, excessive worry or a feeling of impending doom. In most people, anxiety is a typical response to stress and helps one cope with a difficult situation. However, in some individuals the symptoms do become excessive and start to dictate behavior.

The majority of individuals who have chronic anxiety are referred to a psychiatrist or a psychologist. The treatment of anxiety is often a combination of drug therapy and cognitive behavior counseling. However, a number of individuals do poor with conventional medical therapies and have started to seek out alternative health care remedies. One of these therapies is the use of herbs.

There have been a number of herbs which have been evaluated for their role in treating anxiety. The most common herbs used to treat anxiety are kava, passion flower, valerian and theanine.

Kava has been the most studied and is probably the one which is the most sold in health food stores. Several short term studies have shown that it can reduce anxiety in within a few days after starting the herb. The majority of individuals who have taken kava are now unwilling to take any conventional medications.

However, recently there have been reports of Kava and liver damage. There are reports in the literature that after short term use Kava can induce a form of hepatitis and liver failure. In Europe, Kava has been banned from health food stores. In the USA, the FDA has issued warnings to health stores about this herb. Kava is currently widely available in the USA and the FDA is still deciding on its future.
Passion flower, valerian and theanine have also been shown to reduce anxiety and are considered safe. So far the side effects reported have been mild and of a short duration.

One of the major problem with herbs is that the quality and quantity is variable in each formulation. Herbs are sold as dietary supplements and thus often do not undergo the strict quality control required of a drug. Recent reports also indicate that many herbal products from the orient have contaminants; and fake products are not unheard of.

So if you are considering taking a herbal supplement for your anxiety, discuss this with your health care provider. Even though herbs are cheaper than pharmaceutical medications, you do not want to end up paying more to treat complications of these natural remedies.
