can anyone help me on this,years ago i was bushwalking and i brushed past a tree i think it was a peppermint tree
but im not sure.
the reason i ask is i had a drink and wiped my lips and they went num

later on down the track as years went by i hear of people talking about a tree that act's like an anaesthetic or a numing agent.
I would like members help and ideas on this one.

Cheers Simmo
