I like Kavasseur's humility and thoughtfulness in such a posting, but I hope that tudeis don't disappear from cultivation, because they are possibly more medicinal than most other kavas for cancer. At the moment, I am trying to convince an oncologist at my institute to get a clinical trial going. One said last week that he will suggest a person he knows to try it. We'll see where it goes.
A person I know took a mix of tudei and noble kava on my recommendation, and found rapid diminishment of their tumor volumes within the first month. They ate it instead of traditional prep, because they misunderstood/didn't follow my instructions at first. The next 3 months, they used traditional prep, and also showed a decrease in tumor volume, but not as dramatic. Overall, their tumor volume is about 1% of what it was before drinking kava (a few months ago). Chemo was failing, and the tumor was growing rapidly prior to that. So, I hope that there is some availability of tudeis in the future, especially if a clinical trial can definitively show efficacy, because it could have great potential to expand the public perception of kava as a useful herb.
I have only tasted tudei kava twice, in small/moderate quantities. I don't personally feel a need for it, as long as I stay healthy. I understand the fear of what it can do to public opinion, but there should be a way for it to be properly acquired by folks not looking to get stupid, nauseous, and regrettable.
