|Giovanni Battista Ferrari, Hesperides (1646)|
"For a Cold and stuffing in the Head, to draw Rheum from the Head, and comfort the Brain. Take an Orange, and pare off very thin the yellow Rind; rowl it up conveniently to thrust up into the Nostril, turning the inner moist side outward to be next your flesh within the Nose; put a rowl into each Nostril. It will cause sneesing, and will make much water run down at the Nose, and comfort the Brain."
G. Hartman, The True Preserver and Restorer of HealthIf you like your martini with a twist, try your head cold with a twist!
