Medical Properties and Uses. Calumba root is considered a 
powerful antiseptic and tonic, and also possessed of some astrin- 
gent properties ; on which account it is highly recommended in 
diarrhoea, cholera morbus, general debility, and in the last stages 
of phthisis pulmonalis, and in hectic fever ; it has been found to 
check colliquative diarrhcea, to allay nervous irritability, and to im- 
jjart some degree of vigor to the stomach. It has also been con- 
sidered useful in allaying the distressing nausea and vomiting 
which accompany pregnancy ; and in the low stage of puerperal 
fever. It is also an excellent remedy in dyspepsia. Calumba root 
may be given in powder, in doses of from fifteen to thirty grains, 
and repeated once in four or six hours. It is usually, however, 
taken in the form of infusion, either alone, or in combination with 
neutral or alkaline salts, aromatics, or opiates, according as cir- 
cumstances may indicate. By the natives of Mosambique, and 
also by those at a remote distance, this root is considered almost a 
specific for every disorder of long standing ; but more especially 
for dysenterial and venereal disorders. 
The calumba root is considered a most valuable tonic, and is 
most commonly prescribed in the state of infusion. The dose of 
the powder is from ten to thirty grains, and can be repeated three 
or four times a day. It is frequently combined with powdered 
ginger, carbonate of iron, and rhubarb. 
Infusion. — Take of calumba root, bruised, one ounce ; water, 
half a pint. Macerate for six hours in a close vessel, and strain. 
The dose of the infusion thus prepared is one fluid ounce. It 
should be remembered that all infusions of roots prepared in wa- 
ter very soon spoil : therefore, there should be added sufficient 
alcohol to keep it
