It is a very powerful, hence very poisonous drug, its action being due to an active principle known as digitalin.
The effects on animals are identical with those of digitalin.
Give chloride of ammonium in 30 grain doses to prevent delirium; strychnine or digitalin hypodermically.
After distillation the digitalin remains as a grumous crystalline mass, now only contaminated with the coloured oil.
The minutest trace of digitalin moistened with sulphuric and treated with bromine vapour gives a rose colour, turning to mauve.
Prof. Boehm found that digitalin likewise re-established heart action when suspended by the action of muscarin.
digitalin and digitoxin are par excellence the poisonous principles of the plant.
Crystals are in this way obtained, and by removing all substances soluble in ether by that solvent, digitalin may be separated.
Hot water will now dissolve out picrotoxin, colchicin, and digitalin, but not cantharidin.
The alcohol, on evaporation, leaves a mixture of digitalin mixed with other principles and fatty matter.
