In this blog article, we will discuss what Kava is commonly used for and the positive and negative health effects. 

What is Kava? 

Kava is a drug that depresses the central nervous system and acts as a muscle relaxant.

It is commonly used to reduce stress, anxiety, migraines, and insomnia. It is often considered a substitute to intoxicating drink due to hypnotic and muscle- relaxing effects.

The root of the kava plant is ground down and often mixed into various drinks and teas, although it may also be found in the form of a tablet over the counter. 

On the contrary, there is a brand coffee, known the Black insomnia coffee which causes insomnia and still relaxes the muscles.

Background of Kava

Kava is made from the root of the Piper methysticum plant, which is a member of the pepper family.

It originated in the Pacific islands. There, it was ground down and mixed with cold water to create a special drink used in rituals and in ceremonies.

The drink was believed to connect people with spirits. The drink was also a status symbol, drank by those of higher ranks.

Kava was then brought to Australia in the 1980’s, as it was commonly used as a substitute for intoxicating drink due to its muscle- relaxing and hypnotic effects.

Even today, there are café’s selling Kava drinks that market these drinks as an alternative to intoxicating drink. 

Effects of Kava

Kava usually produces the effects of feeling happy, a feeling of well- being, and a feeling of relaxation. It may also lead to sleepiness.

Kava has also been known to produce effects of reduced or loss of appetite as well as a feeling of numbness in the mouth and the throat.

After taking large amounts of Kava, additional effects may be experienced: drowsiness, loss of muscle control, mild fever, nausea, pupil dilation, and eye redness.

Some long- term effects of Kava may include: mood swings, apathy, shortness of breath, dry skin, weight loss and malnutrition.

Kava has also been linked to irreversible liver damage, especially if mixed with intoxicating drinkor an acetonic extract.

For this reason, it is important to avoid drinking intoxicating drink with products including Kava, and to take caution if you have a pre- existing liver condition. 

Overall, the effects of Kava depend on a variety of factors.

It depends on how much Kava you’ve ingested, as well as your size and your overall health.

The effects of Kava may also vary depending on other drugs you are currently taking at the same time.

The effects of Kava also vary if you have taken it in the past. 

Anxiety and Kava

As stated before, the primary use of Kava is to relieve tension and anxiety, and many studies have been performed to investigate this.

The results of the studies show that Kava was in fact more successful at reducing anxiety symptoms than the placebo was.

However, experts say that more studies should be performed in order to fully evaluate the side effects of Kava before it can be a recommended therapy.

Many take it for sleep disorders, as they claim the relaxing effect of Kava can help aid in getting a more restful night’s sleep.

However, studies show that there is no positive nor negative effect of Kava on sleep disorders compared to placebo. 

Risks of Kava

Overall, Kava should be avoided while taking other medications, as minimal research exists on its interactions with other drugs.

You should especially take caution if you are taking benzodiazepines and antidepressants.

Those have similar effects to those of Kava on your central nervous system, and it may create too large of a depressant effect.

You should also not take Kava if you are pregnant or breastfeeding, or if you drive and operate heavy machinery.

Kava should be avoided in children as well.

It should be avoided while drinking intoxicating drink and should also be avoided if you have a preexisting liver condition, as its risk of permanent liver damage is higher in this population.

Despite the research performed on Kava and its effects, the mechanism by which Kava can damage the liver is still not fully clear.

Because of the known risks of Kava as well as the lack of studies available to further elucidate the side effects of this drug, many countries have banned Kava.

However, it is in fact legal in the United States, because various studies have found a very clear positive benefit- to -risk ratio.

The Food and Drug Administration does still issue caution against its use.
