Irritation and itching of the skin, which assumes a bluish
red colour.

_Medicines_. Arnica montana, taken internally or used as outward
application, unless the chilblain be broken, when arsenicum should be
used. If the swelling and irritation do not yield to these remedies
use Belladona and Rhus toxicodendron.

937. Cholera.

i. Bilious or English cholera.

_Symptoms_. Nausea, proceeding to vomiting, griping of the bowels,
watery and offensive evacuations, in which much bile is present,
accompanied with weakness and depression.

_Medicines_. Bryonia, with ipecacuanha at commencement of attack.

ii. Malignant or Asiatic cholera.

_Symptoms_ as in English cholera, but in a more aggravated form,
followed by what is called the "cold stage," marked by great
severity of griping pain in the stomach, accompanied with frequent
and copious watery evacuations, and presently with cramps in all
parts of the body; after which the extremities become chilled, the
pulse scarcely discernible, the result of which is stupor and
ultimately death.

_Medicines_. Camphor, in the form of tincture, in frequent doses,
until the sufferer begins to feel warmth returning to the body, and
perspiration ensues. In the later stages, Cuprum and Veratrum.

938. Tincture of Camphor

Tincture of camphor is one of the most useful of the homoeopathic
remedies in all cases of colic, diarrhoea, etc. In ordinary cases
fifteen drops on sugar may be taken every quarter of an hour until the
pain is allayed. In more aggravated cases, and in cases of cholera, a
few drops may be taken at intervals of from two to five minutes. A
dose of fifteen drops of camphor on sugar tends to counteract a chill
if taken soon after premonitory symptoms show themselves, and act as a
prophylactic against cold.

939. Colic or Stomach-Ache.

This disorder is indicated by griping pains in the bowels, which
sometimes extends upwards into and over the region of the chest.
Sometimes the pain is attended with vomiting and cold perspiration. A
warm bath is useful, and hot flannels, or a jar or bottle filled with
hot water should be applied to the abdomen.

_Medicines_. Aconitum napellus, especially when the abdomen is tender
to the touch, and the patient is feverish; Belladonna for severe
griping and spasmodic pains; Bryonia for bilious colic and diarrhoea;
