Hellebore is a white powder, consisting of the finely ground roots of 
the plant known as white hellebore (veratrum album). It is of little 
value unless it is fresh, or has been kept in a tightly closed vessel. It 
is poisonous to the larger animals when taken in sufficient quantity. 
It may be used dry oras a spray. If it is to be used dry, mix it with 
flour at the rate of one pound of the powder to three pounds of flour, 
and let the material stand over night in a closed vessel. It may then 
be dusted on the plants in any convenient manner. There is no dan- 
ger of burning the foliage. If to be used as a spray, steep one ounce 
of the powder in one gallon of water. 
Hellebore has the advantage that it loses its poisonous properties 
after exposure to the air for three or four days, and therefore may be 
applied with safety to ripening fruits; for example, currants that are 
about ready to use.
