Kava dreams can be amazing. As long as it's good dreaming and not nightmares. The anti-inflammatory effects are very good too. I rarely take NSAIDS anymore unless I don't have kava available. Interesting on the athletes foot. Was it used topically?
Oddly, I also enjoy nightmares on kava, which are fundamentally different than nightmares were before kava. I call them "happy nightmares" because they are not upsetting and usually even have a happy ending, or at least, a satisfactory resolution.
As for athlete's foot, I think kava is effective both topically (I use the greasy green clay like makas left after a Manoan prep, just stick a chunk in there between the toes), but I believe to to be effective also just from drinking kava. What I think happens is rather than boosting the immune system directly, kava deals with a lot of stuff that the immune system would otherwise be occupied with, which frees it up to do what it was originally evolved to do, fighting little infections and such. So, drinking kava doesn't heal the athlete's foot directly, but rather it frees up your immune system to do its job and ward off the fungus.
Of course, this fits in with my grand (and possibly crackpot) theory of kava as the safe uber-anti-inflammatory, and inflammation and immunity problems as being the single source of so many of the different things which ail modern health: cancer, depression, obesity, anxiety, addiction, etc etc. Basically I think modern man suffers inflammation as a result of modern life overwhelming our immune systems, weakening us and making us vulnerable on many many fronts, but the problem is a single one, and so is the answer. Listen to the kava.
