Maywort, those are all normal reactions to Kambo.
The posts in question that you guys are referring to can be located here:

http://kambo.me/smf/index.php?topic=280.msg1759#msg1759I had a discussion about this with Galega via PMs. I seem to have deleted all but one of them.
Read the first 2^^ first, but here is his response:
"Almost! You have to first wash off the Kambo with water to remove all traces. Then keep them as upright as possible and tell them to inhale slowly but only through the nose down into the belly and exhale only through the nose in a long slow blowing motion. Kambo closes the throat but almost never blocks the nasal passages fully until either the head is hanging down over a bucket or the purging has begun.
If they can't manage this, lie them down and do gentle Mouth to Nose - yukky I know but necessary in this case. Mouth to mouth doesn't work if the throat is swollen closed.
With luck the effects will reverse within 60 seconds of removing the Kambo so you don't have to keep this up for long. The biggest problem is panic!
If all else fails, grab your scalpel and do an emergency tracheotomy!

Hope he doesn't mind me sharing a private message, but in the interest of harm reduction.
And this reiterates his first post I linked to about the importance of respect & training, especially in regards to treating others.
hope this helps
cheers! =)
