Mure proved this plant. The most peculiar symptoms were: Saliva profuse,
- milky.
- Ulceration of commissures of lips.
- Costiveness with red urine.
- Vertigo after eating.
- Pain
in humerus on lifting anything. Hot arms with cold hands. "Many of the plants of this genus are
acrid and caustic in the highest degree. The root of P. scandens, the Herbe du Diable of San
Domingo, is a most energetic blistering agent when fresh; so also is that of P. rosea. The beggars
employ P. europea to raise ulcers on their body to excite pity; and used internally it is said to be
- as effectual an emetic as [pecacuanha" (Treas.
- of Bot.
- ).
- In Mure's proving "Aversion to
everything" is noted; also "ulceration of commissures of lips," which is an evidence of its
acridity.
