[DL] shaman power "remedy" opinions

[Deadlander@aol.com]

hi folks, the remedy favour in hexarcana says it can cure supernatural 
poisons and dieseases, do you think this can negate elixers??
i ask because the texas ranger in my group brought a bottle of hair growth 
tonic from a ms and overdosed the apachie shamen with it on purpose and he 
now suffers from alot of long hair that regrows when its cut.
it is very amusing but has really p' ed off the shaman. he has bought the 
above to get rid of it, but im in two minds weather an elixer is a 
supernatural poison, and the fact that as two members of the posse have used 
life giving elixers this would mean the shaman can kill them by using the 
above power.
 any thoughts on this?
