when i first went to californai we had this big ole picnic
way up in pine valley....
and i met a whole bunch of relatives and their kids
so we were all having fun ..... ya know
and then it became time to play hide and seek...
so i hid right in poison OAK which is similar to
poison IVY ok except its a redish color instead.
looks like those poinsettias at christmas-time ...
all i had on was a pair of friggan shorts
so i caught poison IVY (oak) real real bad like on 85%
of my body and it was spreading fast. hospitalization????
there was no pregnazone in those days.
then i stumbled apon "brewer's yeast " a nutritional yeast
left over from making our favorite beverage....
BEER!!
and i started taking it in ice cream milk shakes
wham bam thankyou mam...it turned that situation
around and within a week i was almost poison ivy free.
get it at you nearest health food store....
and any kid with acne - same deal - bye bye 
so use anything ya want topically but give brewers yeast a try
......because it has all the B vitamins and works GREAT!
