1 86. RHGEAS. RED POPPY. The petals of Papa'ver rhce'as Linne, the red or 

 corn poppy of our gardens, growing abundantly as a wild plant in Europe. 

 Nearly round, 50 mm. (2 in.) broad, contracted below into a short blackish 

 claw; when fresh, they are of a scarlet-red color, but become brownish-purple 

 on drying, and have an opium-like odor and a somewhat bitter taste. All 

 parts of the plant contain the alkaloid rhceadine, which produces interesting 

 reactions with acid and alkalies. It does not appear to be poisonous. Acid 

 solutions produce a purple color, which disappears when neutralized. One 

 part of the alkaloid produces a deep purple with 10,000 parts of water, rose 

 with 20,000, and a perceptible redness with 800,000 parts. According to 

 Hesse, the milky juice also contains meconic acid. Red poppy is a weak and 

 uncertain opiate; used in pharmacy almost wholly in the fresh state for color- 

 ing preparations.
