Granny's remedies, made from simple, honest, and generally nearly poisonous 
herbs and roots, were amazing things. After one dose of stomache-ache 
jollop, you made sure you never complained of stomach ache ever again. In 
its way, it was a sort of cure. 
        -- No, not that Granny. The other one.
