Hence the specific name Noli-me-tangere, and the English 
names of Quick-in-hand and Touch-me-not. The elasticity of 
the capsules has furnished names for this plant in most Euro- 
pean languages. In German it is called Spring-same, Spring- 
kraut, &c.; in Swedish, Springkorn ; in Danish, Springkorn or 
Springurt ; in French, Impatiente, Ne me touchez pas, and also 
Balsamine-jaune ; in Italian, Erba impaziente, Balsamina gialla ; 
in Spanish, No quieras tocarme, Balsamina amarilla; in Por- 
tuguese, Melindre nao me toquis. The leaves are said by 
Villars to hang pendant at night; we have not observed this. 
The whole plant is considerably acrid, and no quadruped, except 
perhaps goats, are said to eat it. Notwithstanding this, it 
was formerly used as a diuretic and vulnerary, and was given to 
relieve the hemorrhoids and the strangury. Boerhaave regarded 
it as poisonous.
