Thank you for all that.
If someone had the genetics that made them susceptible to this "dermopathy", would they know right away, or does it often occur later on ?
We don't know to what degree genetics play a role in dermopathy, the genetics I was referring to was in reference to kava's overall safety.
It does seem however, that some people are more (and less) prone to acquiring kava dermopathy. It might be genetic, it might be diet related, not quite sure. But dermopathy is a benign(yet annoying) reversible skin condition, that isn't a real cause for worry, just nuisance.
Dermopathy typically shows up after some steady amount of usage, the time can vary depending on the person. We know that dry kava powder (99.9 % of every kava you can buy online is dry) brings it on worse than fresh kava and that dosage/frequency are the biggest determining factors in getting it, along with the amount of root particles you consume. For example, "toss-n-wash" consumption or drinking a lot of micronized kava are more likely to rapidly produce dermopathy than traditionally prepared medium grind that was strained with a 80 micron or 100 micron bag. If you wanted to avoid dermopathy, then you
would have to cycle your usage, or only drink small daily amounts. There is no guaranteed cycle to avoid it, you'd have to experiment to find what works for you, but drinking it everyday will almost certainly bring it on eventually...the higher the dose, the more severe and quickly it will come on.
