**IMPORTANT INFORMATION REGARDING THE ACETONIC TEST 3/2018** Please note that the results of the "at home" acetonic test are not 100% accurate. In lieu of this we suggest purchasing from vendors who have their kava lab tested and provide access to those results. Introduction Regarding Kava's safety, I will outline what we know so far. Only experts (researchers with a PhD who have authored peer reviewed research) will be included as experts. If you haven't already, please read these thread before continuing so that you can better understand the terminology being used: http://www.kavaforums.com/forum/wiki/kava-definitions/ Dr. Vincent Lebot Dr. Lebot's name will come up quite a bit in the coming article. Therefore, take a little bit of time to read about him below. For those who aren't familiar with Dr. Lebot, he is a (if not, the) leading researcher and authored the book "Kava: The Pacific Elixir". He has a PhD and is a botanical geneticist and has authored 15 peer-reviewed articles, seven of which are related to kava. This link will show you all of his articles in PubMed [there are most likely others, in other databases too]: [http://www.ncbi.nlm.nih.gov/pubmed/?term=lebot, vincent] He has helped to write a piece of legislation called the "Kava Act of 2002" which remains as the only piece of legislation (other than interdictions) for kava. This can be found here: http://faolex.fao.org/docs/html/van38473.htm For more of his thoughts on certain aspects of kava, including safety please see: http://www.kavaforums.com/forum/threads/dr-vincent-lebot-the-kava-expert.2519/ Noble, Tudei, ISA, Explanation and Information Now, when the word "noble" comes up, that means "suitable for everyday drinking". They are interchangeable. "Tudei" is also interchangeable with "ISA", "two-day" and "tuday" as found in the link above regarding definitions. While the Kava Act of 2002 (above) outlines what "noble" kava is, that was referring to Vanuatu specifically. Please keep in mind that the word noble does not refer only to Kava from Vanuatu, as we have as a community, agreed upon. Many kavas outside of Vanuatu are "noble" and Dr. Lebot has confirmed this: A Standard for Kava The industry is working on a way to set up a standard for all Oceanic kava producing nations. You can find that here: http://www.kavaforums.com/forum/attachments/codex-madang-na12_kava_draft-pdf.64/ Also, please see the American Kava Association as they are working tirelessly to do similar things here in the United States. Their mission statement, per their website is: "The American Kava Association is the only national trade association that is focused primarily on Kava Kava. The 3,000 year old traditional Polynesian medicinal root, Kava, has experienced a tremendous resurgence in the United States in the past 10 years. With this resurgence, the need for a regulating body has arisen to oversee the responsible distribution of Kava and ultimately ensure its long term availability in the US market, free from the threat of bans or legislation which would devastate the Kava Market both domestically and abroad. All of AKA’s activities are focused on this mission." Safety of Kava Dr. Vincent Lebot: These studies confirm that kava, as outlined and described by Dr. Lebot above, is completely safe to drink every day. http://www.ncbi.nlm.nih.gov/pubmed/22585547 http://www.ncbi.nlm.nih.gov/pubmed/21112196 http://www.ncbi.nlm.nih.gov/pubmed/21756963 http://www.ncbi.nlm.nih.gov/pubmed/21377431 Kava Historically Safe “As A Water Extract” This from the World Health Organization (found in Codex linked above) "The kava drink, has been consumed in Pacific Island Countries for centuries without any reported ill-effects on the liver , is made from a water extract of the root and/or rhizome of Piper methysticum. A recent WHO risk assessment concluded that “clinical trial of kava have not revealed hepatoxicity as a problem  suggesting that “water extracts are devoid of toxic effects”  and recommending that “products should be developed from water-based suspensions of kava” . The safety of water based kava drinks is supported by long-term ethno-pharmacological observations ." [4.] WHO (2007): Assessment of the risk of hepatotoxicity with kava products, p.4 [5.] WHO (2007): Assessment of the risk of hepatotoxicity with kava products, p. 62 [6.] WHO (2007): Assessment of the risk of hepatotoxicity with kava products, p. 59 [7.] WHO (2007): Assessment of the risk of hepatotoxicity with kava products, p. 62 . Loew & Gaus (2002) in:WHO (2007):, p.11 Regarding Flavokavain B (FKB) As you can see from the abundance of information above, there is no reason to worry. You might, however, have heard of recent discussions about Flavokavain B, or FKB for short. This article is meant only to inform consumers as to the possible risks so that they can make informed decisions about their purchases and consumption of kava. Right now, there is a possible risk with FKB, as research has shown both in vivo (in living organisms) and in vitro (in isolated cells) http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2992378/ These articles demonstrate FKB to be a potent cytotoxin (something that kills cells) in vitro, in isolated cancerous cell lines. This means that they are effective at killing cancerous cells, but doesn't study any other effect they have: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3681603/ http://www.ncbi.nlm.nih.gov/pubmed/22729748 http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3405181/ http://www.ncbi.nlm.nih.gov/pubmed/21377431 The problem is we don't have enough evidence to prove it's safe or dangerous in the amount found in normal daily drinking amounts. However, there is research being conducted currently by Dr. Xing as well as work he has already finished and is awaiting publication that will shed much more light on this subject. What we know from him so far is this statement he made in a recent video interview which can be found here: http://www.kavaforums.com/forum/thr...ultivar-and-that-cultivar-is-tudei-kava.2557/ Taken from transcript compiled from video: Dr. Lebot on tudei kava and FKB: The truth is that no one knows the comparative toxicity of tudei kava to substances like Acetaminophen or alcohol. That sort of information is not available because of how scientists in the research world work, as well as the lack of actual studies testing this specific issue. It is up to you to decide if the risk is worth the benefit based on the evidence outlined above for tudei/ISA kava. Simple Test to Determine if you Kava is Noble ["The Solvent/Acetone Test"] In Dr. Lebot's research, he has created a very simple, cheap and quick way to test a small amount of kava to determine if it is "Noble" or "Tudei" shown in this video: Read on to learn how to test your kava! For information on why this works [New Information Available], please see the comments below because much of the "mystery" behind this test has been addressed by Dr. Lebot. Introduction: Note from KF Mods: This information provided by the acetone test may not be 100% reliable as stated. Science tends to trail behind reality, and as science catches up we will edit and remove that which is no longer relevant. We have removed (as of 3/27/2018) the section regarding the acetone test as being 100% accurate, as it is not. How to Get Started Now: The beauty of this test is its' simplicity and cheap cost. You only need four, cheap and easily accessible things! All you will need is a small glass container, some acetone, and a small amount of kava. Regarding the container, all you need is a small (preferably) glass container of some sort with a lid. I found the vials below for $0.99 as "spice containers" in a big box store. Acetone can be purchased at any home improvement store and is very cheap. Furthermore, all the acetone I came across was quite pure (over 99% purity) The amount of kava doesn't need to be more than a tablespoon (2 flat teaspoons is what I used), so you don't have to worry about wasting your kava! The Method (How to): The test is usually performed with 10g of powder, and 30ml of acetone. However, you do not need a scale if you do not have one. 1. Add 30mL of acetone to (10g) or 2 teaspoons (approx. 10mL) of each kava in a small glass container. If you want to keep it simple, just use the measuring glass and keep the ratio of kava/solent at 1/3 2. Agitate- (shake lightly) for 4 minutes then leave to settle for 24 hours. 3. Then, visually examine the liquid portion (called supernatant) of the suspension for hue, saturation and darkness as described by Lebot as the method of determination of tudei, wichmanii and noble kavas. As a side note, the amount of kava is approximately 10mL if measured in a measuring device, but mL is a measurement of liquid but this might make the ratio easier to understand.
