Digitalis Purpurea
« on: June 10, 2015, 01:43:08 pm »

Digitalis is a genus of about 20 species of herbaceous perennials, shrubs, and biennials commonly called foxgloves.

Due to the presence of the cardiac glycoside digitoxin, the leaves, flowers and seeds of this plant are all poisonous to humans and some animals and can be fatal if ingested.  Symptoms of Digitalis poisoning include a low pulse rate, nausea, vomiting, and uncoordinated contractions of different parts of the heart, leading to cardiac arrest and finally death.

It is used to increase cardiac contractility and as an anti arrhythmic agent to control the heart rate, particularly in the irregular (and often fast) atrial fibrillation. Digitalis is hence often prescribed for patients in atrial fibrillation, especially if they have been diagnosed with congestive heart failure.
