Parsley, Petroselinum Sativum. The fruit is official in the U. S. P. IX and in Sweden and Switzerland, the oil in Denmark and Norway, the root in Austria, France, and Spain.

The oleoresin of parsley seed (Oleoresina Apii or Oleoresina Petroselini) is used in doses of 5 to 15 minims (average, 8 minims) in soluble elastic capsules. Apiol, Parsley Camphor, produces cerebral excitement, as does coffee, followed by a similar intoxication, but vertigo may supervene, with ringing in the ears and severe frontal headache. The dose is 2 to 5 grains in capsules as an emmenagogue in amenorrhea, scanty menstruation, and dysmenorrhea. It should be given immediately preceding the period, so it will stimulate ovarian activity. As shown by Macht {Jour. Phar. and Ex. Ther., July, 1913), apiol inhibits uterine contractions, being paralyzant in action; hence the combination of ergot and apiol is illogical. Apiol is also an inferior antiperiodic in 5-grain doses, and is said to be antipyretic in doses of 5 to 15 grains. These large doses produce cerebral irritation and are not to be commended. Apiol is not an aborti-facient.
