Diuretics operate through the kidneys in the same way.

Diaphoretics aid depletion of the blood by pouring water in the form of
sweat from the surface of the skin and stimulating the discharge of
waste material out of its glands, which has the same effect on the blood
pressure.

Antipyretics are remedies to reduce the temperature. This may be
accomplished by depressing the center in the brain that controls heat
production. Some coal-tar products are very effective in this way, but
they have the disadvantage of depressing the heart, which should always
be kept as strong as possible. If they are used it must be with
knowledge of this fact, and it is well to give heart tonics or
stimulants with them. The temperature of the body may be lowered by cold
packs or by showering with cold water. This is a most useful procedure
in many diseases.

Depressants are drugs which act on the heart. They slow or weaken the
action of this organ and reduce the quantity and force of the current of
the blood which is carried to the point of local disease; they lessen
the vitality of the animal, and for this reason are now used much less
than formerly.

Anodynes quiet the nervous system. Pain in the horse, as in the man, is
one of the important factors in the production of fever, and the dulling
of the former often prevents, or at least reduces, the latter. Anodynes
produce sleep, so as to rest the patient and allow recuperation for the
succeeding struggle of the vitality of the animal against the exhausting
drain of the disease.

The diet of an animal suffering from acute inflammation is a factor of
the greatest importance. An overloaded circulation can be starved to a
reduced quantity and to a less rich quality of blood by reducing the
quantity of feed given to the patient. Feeds of easy digestion do not
tire the already fatigued organs of an animal with a torpid digestive
system. Nourishment will be taken by a suffering brute in the form of
slops and cooling drinks when it would be totally refused if offered in
its ordinary form, as hard oats or dry hay, requiring the labor of
grinding between the teeth and swallowing by the weakened muscles of the
jaws and throat.

Tonics and stimulants are remedies which are used to meet special
indications, as in the case of a feeble heart, and which enter into the
after treatment of inflammatory troubles as well as into the acute
stages of them. They brace up weakened and torpid glands; t
