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.
