Okay acetone test started.
If it is the yellow ill say ok, Must be some kind of personal reaction. But my urine was brown, dunno why. Same with another person who had brown as i linked. I would love to hear from the person who had brown urine from the kona kova and ask what came of that..
But if its that dark color ill take pictures.
Without having a known-noble and a known tudei to test alongside your sample, it's not likely you will be able to tell what you have, unless the result is extremely blatant. There is a sliding scale of hues within the acceptable hues for noble, there is also a varying range for tudei and a mix of noble-tudei can make it even harder for you to perceive the differences.
Just so you know, even pure tudei consumption, though not recommended, is not known to cause immediate liver injury or brown urine in healthy people. Many people drank tudei, or tudei adulterated kava for a long time without experiencing symptoms like you described. When we say kava is safe, that comes with some caveats. Kava is known to be safe when consumed in the appropriate, traditional way and when you and your vital organs are healthy. As you say you are a heavy alcohol drinker who might have liver damage and also consumed a non-traditional extract, those things negate the promise of safety. Most of the rare, but reported cases of kava-related liver injury that emerged in the late '90s, were usually associated with alcoholics drinking non-traditional kava extracts or supplements that were made with kava of unknown quality and/or extracted with alcohol or some other solvent other than water.
I'm not recommending you do this regularly, but there have been studies that show supplementing with Glutathione (or perhaps also NAC), can basically negate any damage that Fk-B does. If you want to drink kava to get yourself off alcohol, it might be a good idea to use that for a while, even if you drink noble kava.
It's typically recommended that alcoholics should ween off alcohol and confirm healthy liver tests before starting kava however.
Also note, in some cases, since noble kava has a varying range of Fk-B in it, albeit in lower quantities than Tudei, it is possible to drink enough noble kava in one day to be equivalent or near equivalent to some varieties of tudei, consumed at a lesser dose. For example, when I drink 9-12 Tbsp of Noble kava, I could ingest the same amount of Fk-B as someone who drinks 3-4 Tbsp of Tudei.
One more thing to note, and again, this is not an endorsement for drinking tudei or for vendors selling it, but the cancer researchers that study Fk-B note that while Fk-B does have the ability to cause cell death, it is many times more likely to destroy cancer cells than normal cells. It is for this reason that they are looking at it to be a possible chemoprevention drug.
The fact is, there isn't enough research done on the human consumption of Fk-B and all the possible variables involved to say precisely how safe or dangerous it is. But we do know that Fk-B heavy kavas will often have a more unpleasant, nauseating effect in most people...and we know that noble kava, prepared traditionally is generally considered to be safe, more desirable in it's effects and we know it's what the natives preferred to drink over the centuries...so we err on the side of caution. That being said, the extreme reaction you appear to have had to what may or may not be tudei is not common or expected and is indicative of something more than simply tudei kava or Fk-B levels.
