Marg. A maid, and stuffed! there's goodly catching of cold.--From Much Ado About Nothing--
Beat. O, God help me! God help me! how long have you professed apprehension?
Marg. Even since you left it. Doth not my wit become me rarely?
Beat. It is not seen enough, you should wear it in your cap. By my troth, I am sick.
Marg. Get you some of this distilled Carduus Benedictus, and lay it to your heart: it is the only thing for a qualm.
Hero. There thou prickest her with a thistle.
If you take Echinacea because people say it will fight a cold, why not try Carduus Benedictus? Shakespeare recommends it and he's better than "people", isn't he?
