If this idea is so dangerous, maybe this community shouldn't have it listed in the first post of a thread that will be one of the first places newcomers are likely to look for guidance. Especially since this is a substance that is currently very easy to obtain and any random fool could take it upon themselves to use the idea and harm themselves.
I was hoping for a more open-minded and educational response but alas. I do see where you're coming from.
By the way, don't worry, I'm not going to rush into anything stupidly or use kambo without sufficient research. I was hoping someone had already tried this method and simply hadn't written about it here, but I'm certainly not going to experiment with it if no one else has. I do think more knowledge about non-burning methods would be helpful especially for USA people since we have a very large stigma around self-injury. Perhaps more people could be helped spiritually if there were "easier" ways. However, I do understand respect for tradition and don't wish to be in any conflict with it, or the medicine itself.
