Sheep feeding on pastures infested with John's wort, frequently exhibit
an irritation of skin about the nose and face, which causes the hair to
drop off from the parts. The irritation sometimes extends over the
entire body. If this plant is eaten in too large quantities, it produces
violent inflammation of the bowels, and is frequently fatal to lambs,
and sometimes to adults.
_Treatment._ Rub a little sulphur and lard on the irritated surface. If
there are symptoms of inflammation of the bowels, this should be put
into the mouth of the sheep with a flattened stick. Abundance of salt is
deemed a _preventive_.
