Ask Kava Guru

While I’ve discussed the origin of Kava and the mythological accounts of Kava a bit – I’ve not really given a thorough account of the movement of Kava through the South Pacific ancestral myths to the Western world’s medicine cabinets. As the West is waking up to the potential of natural products in healing, legal statuses of certain plants are being changed to the point that people can now simply look up “marijuana dispensaries near me” online and find some natural products locally to help them out. So, now I will reveal the all-inclusive article on the origin of Kava. I will do this in hope of divulging a more detailed and rigorous account of the origin of Kava – from when it arrived on earth from the Kava gods to its growth by South Pacific locals, to its Western acquisition, and finally to the actual medicine cabinets of Europe and the rest of the Western world. It’s a lot, but I think it’s just about time I sit down with a cup of Kava and trace the history of this dear plant – fully.

Myth and the Origin of Kava:

To find the origin of Kava, we first need to take a look at the origin of the people who have Kava (or ‘awa as most throughout Oceania call it) deeply entwined within their culture and mythology – the Polynesians. Although historical references are unfortunately scarce and often recorded by “outsiders” such as the European missionaries, the Polynesians nonetheless offer many clues as to how deeply important Kava was to their daily existence and their sacred rituals. Many of these clues can be found trailed through their myths and oral traditions.

The oral traditions, or mythological accounts of the Polynesian people are considered to recount history or ancient happenings through non-written form. Oral tradition is a flexible method of relaying a particular story and is filled with dramatic story enhancers like metaphors and the personification of animals or gods. In oral traditions there isn’t a concrete structure to the stories being told and as a result the same story might vary from orator to orator. While the essential principles or message might remain the same, the setting or character names might change to suit the needs of the person telling the story [12].

While the Western conception of history is based in constructing a set knowledge about the past, Polynesian oral traditions are intended more to gain an understanding or legitimacy for the present way that things are [12]. Given the very different method of constructing the past as non-written, varying stories – it is needless to say quite difficult to determine any kind of factuality about Polynesian history, including the use of Kava.

The true origin of Kava essentially must be left to an account of the myths and legends of South Pacific localities and details of its arrival in the islands and use by the people are essentially left to the gods and deities that flow through Polynesian oral tradition.

From Myth to Cultivar:

While our exact knowledge basis of Kava and its use by the Polynesian people is quite limited — because of the nature of the historical records – we can nonetheless construct a semi-thorough understanding of the ancient use of Kava through an analysis of bits and pieces collected from research papers, myths, and other texts. One thing that many ethnobotanists seem to consistently agree upon is that Piper methysticum – the kava kava plant – came from Piper wichmannii, a wild plant that scientists say is in the direct botanical lineage of Piper methysticum. Given that Piper methysticum is a cultivar, it essentially cannot propagate or adapt without human interaction and as a result it is believed that it was adapted from a wild plant of the same species [7]. Vincent Lebot, along with several other authors on Kava, stated that essentially all of the worthwhile evidence on the topic indicates that the plant Piper methysticum is a cultivar of Piper wichmannii. Piper wichmannii is a fertile plant that is morphologically similar to Piper methysticum. Furthermore, Piper wichmannii is the only known varietal in the wild to carry a high quantity of kavalactones like Piper methysticum, and it has an almost identical chemotype as some Piper methysticum cultivars [1].

The points highlighted above only touch the surface of evidence indicating that Piper methysticum is the direct result of Piper wichmannii cultivation, but they nonetheless serve to illustrate just how vastly detailed the body of evidence is. Over the centuries each South Pacific region has established a unique cultivar with its own chemical profile [5].

Although New Guinea has the most varied population of Piper wichmannii, and is thus a contender for the origin of its cultivar Piper methysticum, there isn’t enough concrete evidence or historical data to determine just where Piper wichmannii came from or how it evolved. Where Piper wichmannii came from is perhaps a story that must be left to the gods of South Pacific mythology. One myth tells of a godly and heroic entity named Mwatiktiki, who comes from some far off place to Tanna – an island in Vanuatu. This being places the original kava kava plant between rocks by the shore. Two local women happen upon the plant and have pleasurable experiences with it. They then bring it back to their localities and cultivate it, eventually sharing its joys with their fellow villagers [10]. Presumably, this mythological story is speaking of the discovery of Piper wichmannii, which was then farmed and cultivated by the people of Vanuatu.

European Acquisition, Captain Cook and the Missionaries:

While many history texts construct Captain Cook as a hero of sorts, a person of great determination and one to be thanked for many things – the account of locals from the places he landed during his adventures tells of quite a different character. Even the historical references recorded by “outsiders”, such as the European missionaries and Captain Cook himself, offer many clues as to how deeply important Kava was to the South Pacific Islanders’ daily existence and their sacred rituals and how this divine root made its way to Europe and other continents.

The sources are inconsistent with regard to Captain Cook and his involvement with Kava and the culture surrounding it. Some sources depict his adventure to the South Pacific Islands as one of great immersion and enjoyment in Kava culture, while other sources emphasize his and his crew’s disdain for the drink and their especial disgust with the process of making it: “Kava is made in the most disgustful manner that can be imagined…they swallow this nauseous stuff as fast as possible…” [13].

One source that highlights Cook’s disapproval of the drink states the following as coming from Cook’s own texts:

“The Excess with which the Chief[s] drink the Kava, destroys their Strength & makes them sad objects of Debauchery, they far outdo in the use of this pernicious root all the other Indians we have vist’d; the more Scaly their bodies are, the more honourable it is with them. . . . Many before they are forty are miserable Objects, their whole frame trembles, their Eyes are so sore & reddened, that they seem in Constant pain; yet I believe in a short time by disusing this liq- uor the soreness of the Eyes goes away; at least we made some of our friends refrain & they re- covered amazingly”[5].

Yet, Gananath Obeyesekere – the author of The Apotheosis of Captain Cook: European Mythmaking in the Pacific – illuminates another side to the story:

“Sociability and decorum drew Cook into the Kava circle of Tongan chiefly life. They were repelled by the way that it was brewed, but Cook was impressed by the sociability it fostered. Cook was invited to a Kava circle by Paulaho the “king” on 7 June, only four days after landing in Nomuka. Soon Cook was fully ensconced in the Kava circle, so that Lieutenant Williamson noted on 17 July that ‘Captain Cook often drank of it, holding it as an argument that seamen should eat and drink everything…'” [8]

While it’s unclear whether or not Captain Cook actually favored the Kava drink, given that the sources on the matter are inconsistent – it can be said for certain that the missionaries loathed the entire concept of Kava and Kava culture and its religious underpinnings. Unfortunately, even from a purely objective viewpoint, these European missionaries, according to their own recorded documents, went to great lengths to obliterate the culture of the Polynesians in order to overlay Christianity onto various peoples with a brutality that I will do my best to only touch upon as necessary to illustrate key points on this particular journey of discovery. As part of this, the missionaries made it their Christian duty to obliterate Kava and its consumption.

First, it appears that Polynesians were so intricately connected with nature, that they had no concept of the “supernatural” or “spiritual” as defined by modern or “book” religions as I call them. To the Polynesians, everything belonged to nature, whether it was their own existence, the plants and animals they coexisted with and often consumed, the living gods among them as chiefs (we would call them demigods), or the gods who ruled the plants, the land, the seas, the skies, and the stars that guided their daily lives and controlled the forces of nature.

The Polynesians revere their gods as “departed ancestors” who lived among them long ago. The Polynesian reverence for their elders thus makes complete sense, as their elders are the closest living connection to their gods. Chiefs were typically chosen because of their physical prowess, their robustness in size and stature, and were trained in warfare from the time they were boys. Chiefs were also on the front lines in battles, and weren’t just warriors, but were also decision makers in every aspect of Polynesian life.

There are several “venerated spirits” in Polynesian culture that stand out from the rest. These gods were the most distant ancestors, and the greatest providers of “mana” (spiritual power). These gods are “Tu” (Ku in Hawaiian), “Tane” (Kane in Hawaiian), “Kongo” (Lono in Hawaiian), and “Tangaroa” (Kanaloa in Hawaiian). All were children of the sky father and earth mother. Kava is often mentioned in Hawaiian culture along with Kane and Kanaloa; Kane is a god of good and Kanaloa is a mischievous, rebellious god often associated with the Christian devil.

One example is a standard prayer of offerings in exchange for health for individuals and their families; “O Kane, O Kanaloa, here is the taro, the bananas, here is the sugar-cane, the ‘awa.”

According to Hawaiian Mythology, “Kane and Kanaloa are described in legend as cultivators, ‘awa drinkers, and water finders, who migrated from Kahiki and traveled about the islands. It is as ‘awa drinkers that the water-finding activities of these gods are employed in some stories, because ‘awa is their principal food and they must have fresh water with which to mix it.”

‘Kahiki’ is the Hawaiian, somewhat out of use, name for Tahiti – a region in the South Pacific. The Hawaiian people revere Kahiki as the ancestral land from which the Hawaiian people came from and from where their ‘akua’ or supernatural being originated [3]. This understanding of Kahiki, as an ancestral land, probably also sheds some light on the question of how Kava came to Hawaii. As mentioned above the Polynesians believed their gods to be born from their ancestral lineage. Furthermore, much of Kava mythology explains that Kava came from the gods or a god [10], thus providing the link between Hawaiian ancestry – as understood by them – and the acquisition of Kava.

However, given this indigenous religion of the South Pacific island communities, Christian missionaries found it fit to invoke a dogmatic cleansing of the culture – a cleansing that included banning and destroying Kava. In Hawaii during the 1820’s, Queen Ka’ahumanu declared that neither chiefs nor anyone else were permitted to drink ‘awa and that it was also not to be planted; this happened just a few years after the missionaries arrived and were implementing Christianity. However, one missionary – John S. Emerson – wrote of how these prohibitions were being greatly violated. As a result of further pressures and dogmatic action, ‘awa was thrown into the legal books and laws surrounding its use were enacted – its permitted use was solely medicinal. Sadly, there are far fewer cultivars now in Hawaii as a direct result of this ‘purity cleansing’ – some estimate that there may have been up to 35 various cultivars prior to missionary involvement [5].

Yadhu Singh explains how when the evangelical missionaries arrived in various places within the Polynesian islands, there was a “disruption of the traditional way of life”, and that alcohol and other more pharmacological substances began to be introduced and replaced Kava.

Despite the missionaries’ attempted indoctrination of the Polynesian communities, Kava survived and has made a comeback and is actually very much still popular in most South Pacific island communities. Singh suggests that the resurgence might have been due in part to the development of the John Frum cargo cult, which was an uprising directly in repudiation of Christian teachings. Carlton Gadjusek – a noble Laureate – noted that the Kava-drinking tradition of Tongariki was more like that of the Kava-drinking tradition of the Frum cult out of Tanna, given its lack of formality and restraint [10].

Transition into Western Medicinal World:

There was however one beneficial result of the missionaries’ circulation throughout the islands. It’s quite likely that many of the nations neighboring the Polynesian Kava-growing communities learned about Kava from the missionaries who had traveled through those islands. Singh tells us how the Australian Aborigines were unaware of Kava until the early 1980’s when missionaries came from islands like Fiji and Tonga [10]. Although, other island nations like Hawaii, probably received ‘awa from neighboring island communities, as their mythology suggests [5].

While there is no direct documentation of how Kava first arrived in Europe and other continents outside of the Polynesian regions, it’s fairly safe to assume it was brought over by the missionaries and crew of the Captain Cook voyages. However, until the mid 1990’s the major demand for Kava remained within the South Pacific islands – after 1996, import into Europe and elsewhere began to increase dramatically, with a decrease during the reign of Kava bans [10]. While there was a growing interest in Kava – throughout Europe and elsewhere – with an especially keen interest in its anxiolytic qualities, there was a ban in the early 2000’s that reverberated throughout many North American and European countries, nearly wiping out the export of Kava from the South Pacific islands. I speculate and draw out the details of this ban in other articles and so I won’t go into much detail here. But, essentially the ban was initiated by the German Bundesinstitut für Arzneimittel und Medizinprodukte (in English, Federal Institute for Drugs and Medicinal Devices) and was later (fairly recently) declared to be unfounded and the ban was lifted in Germany; the ban was lifted in North America and other places prior to the recent developments in Germany [9].

Today, some places such as Australia still have restrictions on the import of Kava [2] – however, the restrictions are minimal and Kava is generally accepted worldwide now, slowly recovering from the bans placed throughout the 1990’s and early 2000’s. For example, in Canada, Kava is no longer banned and the sale of Kava to individuals for personal consumption is permitted – although it’s unclear what the exact status is on commercial sales within Canada [6].

Outside of the South Pacific, Kava is predominantly used as a social beverage for personal relaxation and anxiety relief. For example, in the States there is a growing number of Kava bars – a social place where people can go to hang out with friends, relax and drink Kava beverages. However, probably its most widespread notoriety outside of the South Pacific islands is the use of Kava as an anxiolytic (anti-anxiety) substance in alternative medicine [5]. Many studies have been conducted that conclude that the use of Kava to treat anxiety is effective, and even better than pharmaceutical options, given that it is non-addictive and actually improves cognitive function rather than impairing it as other options do [11]. Many people are increasingly looking towards alternative methods of relieving their anxiety. One such method is the use of CBD and, as people learn more about the substance, they are improving the ways in which it can be absorbed into the body, like developing it in a water-soluble form for easy absorption. Also, when it comes to using cannabis-based products for de-stressing, most people prefer smoking medical or Recreational Cannabis, although there are a lot of other ways to consume CBD or other cannabis-related products. For instance, many people who use cannabis or CBD often vape, use tinctures, or eat edibles. In fact, you can even buy edibles online as well as the other forms of CBD and cannabis-based products from an online or local dispensary.

Ahhh, well I’m now through several shells of Kava and ready for a lovely snooze. I hope this somewhat historical document outlining the route of Kava, from myth to alternative medicine, has been helpful. Kava certainly has had quite the journey, from its divine origin, to its mainstream island culture, to its Christian prohibition, and finally to its more recent debut in Europe and North America. I sure am grateful that the missionaries didn’t have complete success in their dogmatic infiltration and I’m also glad that Captain Cook didn’t totally hate Kava (as some sources might suggest) – as was noted above, even Captain Cook couldn’t resist the lure of the mystifying Piper methysticum.

There have actually been quite a number of studies regarding reaction times with Kava on its own, when combined with benzodiazepines, and even alcohol.  The results are quite interesting, and definitely score another clear victory for Kava.

First, in 1993, a group of researchers investigated the effects of kava extract, a benzodiazepine (a general group of anti-anxiety drugs), and a placebo on behavior and event-related potentials in a word-recognition memory task.  The task was structured as a memory task designed as a double-blind crossover study in 12 healthy volunteers.  In the word-recognition test, oxazepam elicited “a pronounced slowing of reaction time and a reduction in the number of correct responses… observed.”  Wow.  They go on to further state, “The behavioral indices indicated a greatly impaired performance after oxazepam and an enhanced memory performance following kava.”[1]  Wow again!

Across the board, kava not only did not decrease reaction time, it was shown to improve reaction time in word-recognition tasks.

Also in 1993, a group of researchers assigned 24 subjects (11 male, 13 female) to receive a drink consisting of kava and fruit juice.  The drink containted 500 mL of 0.2 g/mL kavalactone, blended with 500 mL of fruit juice.  The test group was subjected to a wider range of tests that included cognitive performance, physiological functions, and mood.  No differences were found between the kava drinkers and the control group in measurements of various psychological parameters, including respiration, heart rate, blood pressure, and stress levels.  Although what was not measured is what was most interesting, the researchers did conclude that kava, at least at the above dose, does not impair one’s cognitive functioning[2].

As a third example to present you with, there was a study conducted in 1989 by Saletu and co-workers.  The purpose of their study was to measure the physiological effects of kavain, a main kavalactone in kava, on brain activity compared to the benzodiazepine drug clobazapam [3]. In this placebo-controlled double-blind study, 15 healthy volunteers received single oral doses of either an inactive placebo, 30mg of clobazapam, or synthetic kavain at either 200, 400, or 600mg [3].

The researchers recorded the subjects’ EEG (electroencephalogram, a measure of brain wave activity) and other psychophysiological measures every 2 hours for 8 hours during each study session. The EEGs showed that, though kavain exerted a significant effect on brain waves, it modulated this activity differently than the clobazapam; specifically, the kavain increased delta, theta and alpha waves while decreasing beta waves (the clobazapam showed the opposite effect)[3].

Even more encouragingly, the psychophysiological tests given by the researchers determined that subjects who had taken the kavain showed behavioral improvements in attention, reaction time, motor reflex, and intellectual performance. The people in the kavain group also noted improvements in mood, alertness and feelings of well-being after taking 200mg of kavain. The 600mg dose produced greater sedation, but still less than the clobazapam [3].

The last example I’ll offer is a study in 1987 by a team of researchers led by Russell [4].  The purpose of their study was to assess the effects of a low dose of kava on alertness, as well as the speed of accessing information from long-term memory. Posner’s letter-recognition task was used to measure the speed and accuracy of long-term memory access: subjects have to press a button within a time limit to indicate whether a pair of letters appearing on a screen is identical to a previous pair, the same sequence in a different font, or a different letter pair [4].

Russell’s study involved two rounds of testing. In the first, 9 healthy subjects (5 male, 4 female) were given 250ml of water infused with 30g of kava root and tested against a control group given no kava. the Posner test was then repeated a few days later with the same experimental group, this time given 500ml of water infused with kava at a rate of 1g/kg of body weight [4].

And surprise, surprise… the researchers reported no differences in speed of long-term memory access or error rate between the control group and the people who had taken kava! In their conclusion, they wrote the result demonstrated that kava acts to induce relaxation without impairing memory, reaction time or mental focus–indeed, [3] and [1] show mental focus actually improves with kava. So you can imbibe your kava with confidence, knowing that not only will kava not impair reaction time, it can actually benefit it!

This is a question I get asked so often, and it’s a wonder at how much literature there is on the topic. Well, if you think about it, ‘Kava combinations’ is quite a broad topic, since the combinations of interest can range from herbal to pharmaceutical and everything in between! So, there’s a lot of information here – and I’ve done my best to break it down and pick out the most important Kava combinations from the masses of research that there are on various combinations with Kava and their interactions. If you don’t see your combinations of interest here – go ahead and summon my guru wisdom. How can you summon my wisdom? By simply asking!

Herbal Combinations:

Naturally, many people instinctively combine other medicinal herbs with kava kava, thinking something along the lines of “Hey it’s all natural – why not throw it all together and reap multiple benefits!” But, it’s important to realize that- as with Kava – many medicinal herbs (such as the duke nukem strain of cannabis) have biochemical interactions with the body that could alter the functioning of enzymes, hormones, or other biochemical components of the body. For comfort reasons, people often try to partake of this one via a fat buddha glass bong, or a similar product, as this can help those biochemicals enter the body. For example, Kava inhibits the CYP 450 enzymatic pathway, and as a result any herbal treatment that is metabolized by these enzymes cannot be properly metabolized and there may be resultant health risks [5]. It’s possible then that certain chemical reactions or states might not mix well with each other. As a result – it’s always wise to err on the side of caution and do a bit of research before combining Kava with other herbs or plants. So, to help you out I’ve put together some of my own research with regard to combining Kava and other popular herbal remedies.

Sedatives: (lavender, passionflower, valerian, chamomile, hops)

The general consensus within the field of herbal interactions is that you will experience a heightened sedative effect when combining any other herbal sedative with Kava; this is an effect that may or may not be desirable [1, 3, 6]. Since Kava is in some way also a sedative and acts on the same enzymatic pathways – the two naturally coincide. In terms of safety there isn’t really any information with regard to Kava and herbal mixture health concerns or precautions. But, nonetheless you should always research your combination of interest or ask a health practitioner.

Passiflora (Passionflower): One study directly monitored the effect of passionflower and Kava alone and in combination. The results indicated that there was a doubling effect, meaning that the combination of the two increased the effect of each individually by 50%. The study demonstrated that in terms of sedative effects, there was a 91.6% prolongation of sleep duration when the combination of kava kava and passionflower was administered [3].

Valerian: There was an extensive study conducted on the effects of Kava and Valerian independently and combined with each other. The results indicated heightened levels of stress reduction and anxiety alleviation in three categories: social, personal and life events. Also, there was a significant improvement with subjects experiencing insomnia – ie. insomnia was decreased. One of the most common effects indicated by the subjects who took the combination of Kava and Valerian was vivid dreaming [8].

Stimulants: (coffee, kola nut, máte, guaraná)

Unfortunately, there isn’t too much information available with regard to the safety of combining Kava with herbal stimulants or their interactions. But, generally speaking, it’s unwise to combine kava kava with any herbal stimulant, and probably any synthetic stimulant as well. Quite generally – it’s unwise and counterproductive to combine stimulants and sedatives, because of their counteractions on the same or relatively similar biochemical compounds [6]. If you’re looking for something to calm you down, you take a sedative — you don’t want to then take a stimulant and undo what you’re trying to accomplish.

For example, coffee and Kava probably interfere with each other and their relative performance. It’s quite possible that Kava aggravates dopamine or dopamine receptors, meaning that it interferes with its release [2]. If this is the case, then something like coffee – a natural substance that stimulates the release of dopamine [7] – will naturally compete with Kava because each is trying to do a different thing to your biochemical system.

Combination with Alcohol:

Ahhh, now to discuss the single most commonly searched Kava combination – alcohol and Kava. I won’t go into too much detail here, as I’ve unloaded much of my wisdom on another post with regard to combining alcohol and Kava; I’ve posted the link below.

But, I will say very generally that although people often combine Kava and alcohol and have remained alive to tell the story – it isn’t necessarily very safe or wise to do so. There are several studies on the combination of Kava and alcohol and the general consensus of all of these studies is that you should never combine Kava and alcohol, as the combination of the two greatly increases your chance of hepatotoxicity (toxicity of the liver).

Besides, why not just drink Kava instead of alcohol altogether? Many people actually prefer to drink Kava over alcohol – given that it has very similar effects, and is generally considered to be a nonaddicting and healthy alternative to drinking alcohol.

More Information on Combining Alcohol and Kava

Pharmaceutical Drug Interactions:

In the case of Kava combinations with pharmaceutical drugs – it is imperative that you seek medical advice from a practitioner or at least do some research on the interaction of the two substances. Yadhu N. Singh suggests that pharmaceutical interactions could be the most significant of the Kava combinations. Kavalactones – the beneficial compounds in Kava – inhibit cytochrome P 450 (CYP 450) [5]. CYP 450 is an enzyme that acts as a catalyst in the process of oxidizing organic substances. However, most importantly, it is a major enzyme category used by the body for the metabolization of drugs [8]. Given that these enzymes are inhibited by Kava, Kava may then prevent the body from properly metabolizing pharmaceutical drugs [5]. As a result it is extremely important that you do your research before combining Kava with any pharmaceutical drug. I’ve put together some information on the most common Kava and pharmaceutical interactions – hopefully you’ll find your answers!

Central Nervous System Agents (Benzodiazepines): Given that Kava and Benzodiazepines act on the same CNS receptors, it is likely that the combination adds to the effects caused individually by each and/or has at least a synergistic pairing with each other (ie. increases the effects of each substance). Also, Kava will add to the drowsiness that is stereotypically experienced by those who use benzodiazepines [2]. With this being said, there are many alternatives to benzodiazepines that you can look into, if you are noticing that you are experiencing many side effects from taking this medication. It is important to speak to a professional first, before making any decisions regarding your health. This is due to the benzodiazepines’ addictive ability. There are many who find themselves addicted to the medication, with some needing professional help to break the addiction. Rehab centers often use drug tests in order to determine whether or not patients are using the drug while staying with them. To learn more about benzodiazepine drug tests – see https://www.countrywidetesting.com/collections/benzodiazepines-bzo-drug-tests.

Anesthetic Agents: Kava is actually considered to be an anesthetic itself and has been reported to have muscle relaxant effects as well as inducing numbness. Since anesthetics are intended to essentially do exactly the same thing – relax and numb muscles/tissues – there will inevitably be synergistic effects and Kava will prolong and intensify the effects of the anesthetic [2]. It’s actually recommended to not ingest Kava before going in for surgery for precisely the reason mentioned above – that there will be an interference with the functioning of the pharmaceutical anesthetics that you will be given [1].

Analgesics or Painkillers (Acetaminophen, ibuprofen, aspirin, Percocet): There is an increased chance of liver damage or hepatotoxicity and kidney damage when Kava and pharmaceutical painkillers are taken simultaneously. As a result it is simply wise to avoid this combination [2].

Diuretics (acetazolamide, amiloride, furosemide and ACE inhibitors such as benazepril, captopril, lisinopril, quinapril and ramipril): Kava is a diuretic itself and also does cause dehydration, so if Kava is combined with pharmaceutical or herbal diuretics it will likely add to the effects and increase dehydration [10, 1].

Psychoactive Drugs (Xanax): While there is one reported case of coma induction, which is possibly linked to the combination of Kava with Xanax [4], it is nonetheless unclear what the exact biochemical interaction is like.

Dopamine agonists/antagonists (Xanax, prozac, droperidol, haloperidol, risperidol, metoclopramide, and other antidepressants or anti-anxiety medications): As was mentioned above in relation to coffee – Kava is reported to be an antagonist of dopamine; meaning, Kava inhibits dopamine receptors and transmitters. As a result Kava can either act as an additive to the effects of pharmaceutical dopamine antagonists or an inhibitor in the case of the combination with dopamine agonists [1].

As you can see there are a TON of possible interactions that Kava may have with herbal and plant-based remedies or pharmaceutical medications. If your health is as important to you as it is to us – then hopefully you have read this article and are doing further research on the particular Kava combination you have in mind. If you don’t see information on the Kava combination you seek to gain knowledge about, please do ask me! My guru wisdom is pretty much endless when it comes to many topics and I would love to share as much as possible with my readers – but of course sometimes it’s not possible to cover everything. That’s where you come in! I love to get some direction from my readers telling me what it is exactly they want to know about. In the meantime, I hope that this has helped!

A few quick tips to remember:

– It is unwise to combine Kava with alcohol – rather, use Kava as a healthy alternative!

– Always consult a physician when wanting to combine Kava with a pharmaceutical drug.

– Kava acts on CYP 450 enzymes, as do many herbal and pharmaceutical remedies – so, be careful when combining them! These enzymes metabolize some herbs and medicines, so Kava could interfere with the metabolization process or have other undesirable biochemical interactions.
