Respiration flower

Rhoeadine (R = CH3) was isolated for the first time by Hesse (665) in 1865. It has always been considered to be ineffective physiologically as well as poisonous. In children, the sedative and slightly expectorant effect of the syrup prepared from the flowers of P. rhoeas L. (where rhoeadine is the major alkaloid) could not be explained, nor can it be explained why cattle avoid P. rhoeas (666). Hakim (667) observed, after administration of seed oil and extracts from poppy heads of P. rhoeas, an increase in intraocular pressure in rabbits. Lieb and Scherf (372) administered rhoeadine to rabbits and found a significant decrease in intraocular pressure, mydriasis, and a slight stimulation of respiration. For details refer to Section II, N on the benzophenanthri-dine alkaloids. The increase in intraocular pressure is apparently not caused by rhoeadine. Awe (668) observed spasms after administration... 

The inflorescence of the dead horse arum Helicodiceros muscivorus (Araceae), distributed in the western Mediterranean regions, mimics a dead mammal and emits an oligosulfide odor, which includes dimethyl sulfide, dimethyl disulfide, and dimethyl trisulfide.104 The flower odor is crucial for attracting blowflies, which serve as important pollinators for this flower. In addition, the thermogenesis and respiration of the inflorescence reinforce the stimulation for fly pollination.10...

WATER DROPWORT Oenanthe aquatica, L., Poir., Family Apiaceae, grows in ponds and small lakes in Europe. The flowers are the most poisonous, followed by root, fruit and stem. Phellandrene, which has an abortive action, gives first a stimulating effect and then inhibition of respiration. Oenanthin provokes vomiting and oenanthotoxin is a poison that gives epilepsy-like convulsions.

Overdose of coltsfoot flower bud may cause restlessness, excitation, irritability, and increased respiration (Chen and Chen 2004). 

The LD50 values of different preparations of coltsfoot flower bud in mice are 124 g/kg after oral administration of a decoction, 112 g/kg after intraperitoneal administration of an alcohol extract, and 43 g/kg after intraperitoneal administration of an ether extract (Chen and Chen 2004). Overdose of the flower bud led to restlessness, excitation, mania, increased respiration, muscle stiffness, tremor, and muscle spasms (Chen and Chen 2004). 

Another early convert was Count Carlo Lodovico Morozzo (Mouroux) (Turin 5 August 1744-2 July 1804), general in the army of Piedmont, who published on the purification of air by plants, the composition of air, the colours of flowers and other vegetables, eudiometry of pure air and air vitiated by animal respiration, the gases obtained from dew, animal colours, the absorption of air by charcoal, and the respiration of oxygen. ...
