kava plant leaf alternative medicine

One of the folk medicines commonly used by South Pacific Islanders is a root called Kava or kava kava. In this article, we will discuss some of the important information about this emerging plant-based substance, its effects to human health, and the buzz surrounding it.

What is Kava?

Kava is also known as piper methysticum. Its roots and stems are made into non-alcoholic beverages commonly enjoyed socially and in ceremonies for many centuries in Fiji, Hawaii and Tonga.

Due to its calming effect, its action is very much similar to anti-anxiety drug like diazepam. It also has the ability to prevent convulsions and aid in muscle relaxation. Kava is prepared as a tea, and is also available in powder or tincture forms.

Kava is also known in the following names:

  • Lewena
  • Yaqona
  • Grog
  • Sakau
  • ‘awa
  • ‘ava
  • Wati

Kava comes in different forms such as:

  • Drops
  • Extracts
  • Capsules
  • Brownish-colored drinks
  • Brown powder

Uses of Kava

The calming effect from taking kava may relieve the following conditions:

  • Stress-related symptoms such as muscle tension and spasm
  • Restlessness
  • Sleeplessness
  • Anxiety
  • Urinary tract infection
  • Migraine
  • Epilepsy
  • Leprosy (skin application)
  • Muscle pain
  • Venereal disease

What is good about kava is that when it is used to treat anxiety or stress, it does not interfere with mental sharpness. Kava contains compounds that are responsible for the psychoactive qualities in the brain that offers a non-narcotic action against anxiety. This means that it is safe to use compared to the usual prescribed antidepressants.

Duke University Medical Center discovered in a study that apart from it being effective is that it doesn’t produce dependence or adverse effects in blood pressure, heart rate or sexual function. It is a good candidate for future research as treatment in improving attention disorders in children.

Another study showed that kava may be helpful for women who are going through menopause. One of the significant symptoms of menopausal women is having mood swings. Using kava may somehow help them to have a more pleasant mood without affecting the therapeutic actions of estrogen. It was also found out that it has helped increased libido among menopausal women.

The government spends a huge budget in treating addiction. Some studies have shown that using kava as a treatment for addiction may be an effective and inexpensive solution. Kava can help in reducing drug cravings with the help of a compound called kavapyrones.

When it is taken as a sleep aid, it generally promotes deep sleep without affecting restful REM sleep.

The only thing that should be strictly avoided is taking kava with alcohol, which may produce unfavorable effects like impaired reflexes, increased drowsiness and risk of liver damage. Meanwhile, taking kava with antidepressant induces sedation.

How is Kava prepared?

Kava is prepared by placing both roots and stem into a sack, submerging them in water, and squeezing out its juice into a bowl. The liquid extract may be placed in individual cups for drinking.

Its effect is experienced shortly after taking one to two cups. It has an earthy flavor which may take time to get used to.

Experts in studying kava recommend using it not more than three months; otherwise, it may lead to liver failure. Prior to taking kava, you should be aware of the following facts:
