"CONSTITUENTS: Lobeline, Lobelachrin, Lobelia acid.
PREPARATIONS: Extractum Lobeliae Fluidum, Fluid Extract of Lobelia; dose: from one to ten minims. Tinctura Lobeliae, Tincture of Lobelia; dose: from five to thirty. Specific Medicine Lobelia; dose: from one to twenty minims. Subculoid (hypodermic) Lobelia; dose: from two to sixty minims; usually from ten or thirty minims repeated as occasion demands.
Therapy: In spasmodic asthma, if given in a dose of from thirty minims to one dram during the paroxysm, the benefit is apparent almost immediately. Small doses are of but little or no benefit in such a case. This full dose may be once repeated, but this is seldom necessary, and a single dose seldom produces vomiting. It is useful in asthmatic breathing. When continued with other agents it must be given in doses not to exceed ten minims three or four times a day.
Lobelia is of value in whooping-cough. It is a reliable expectorant, and either alone or in combination with other indicated remedies, is useful in all cases of dry, hard, barking cough, or where the expectoration is difficult to raise, in spasmodic croup, and in membranous croup without depression.
Children are less liable to be unpleasantly affected with Lobelia than adults...."
