Anyone tried this or got any info on it ? The name in chinese characters would be most useful. I have been asking for "yun shih" in herbalists in Guangdong and have been shown a root but I need more research to work out if it is the same "plant of the gods".

Also wondering if the root is effective and with what quantity / method.

I asked the guy in a shop if their root would help me see other worlds and he looked a bit taken aback. Maybe safer to ask if it enhances mental capabilities. Language is, of course, an issue !!!
