My mom has always been a proponent of marijuana use for medicinal purposes ~ two of her sisters were very ill, one with cancer and the other with asthma. My grandmother (this was in the thirties and forties before marijuana usage became illegal in SA) used to make a tea out of the leaves for her daughters and this would alleviate the symptoms a great deal.
My mom did tell me once that she tried the tea and nearly threw up because it was bitter, bitter.
