	Digitalis BP
		Digitalis is contra-indicated in ventricular tachyrardia, and in sinus tachycardia, unless there are definite signs of congestive failure Caution should be exercised, and large doses avoided, in acute lesions of the myocardium, such as rheumatic carditis and cardiac infarction.
		Other responses to digitalis, such as slowing of the heart-rate, increase in cardiac output, decrease in cardiac enlargement, reduction in venous pressure and improvement in renal function, are all explained on the basis of this action.
		If digitalis cannot be given orally the tincture may be given by rectal injection, or suppositories of powdered digitalis may be employed; the doses, intervals between doses, and the time necessary to obtain cardiac effects are the same for rectal as for oral administration.

	Poisonous Plants: Foxglove, Digitalis (Digitalis purpurea & lanata)
		Digitalis is a perennial herbaceous plant, up to 120 cm high, and has long leaves.
		At that time, digitalis was used in enormous doses exclusively as a laxative drug that led to many severe poisonings and deaths, which is why it was consequently rejected.
		However, it was not until 1850 that the effect of digitalis on the heart muscle was revealed by the German pharmacologist Traube.

	Digitalis - Wikipedia, the free encyclopedia
		Digitalis is a genus of about 20 species of herbaceous biennials, perennials and shrubs that was traditionally placed in the figwort family Scrophulariaceae.
		Digitalis toxicity (Digitalis intoxication) results from an overdose of digitalis and causes anorexia, nausea, vomiting and diarrhoea, as well as sometimes resulting in xanthopsia (jaundiced or yellow vision) and the appearance of blurred outlines (halos).
		Digitalis is a classic example of a drug derived from a plant formerly used by folklorists and herbalists: herbalists have largely abandoned its use because of its narrow therapeutic index and the difficulty of determining the amount of active drug in herbal preparations.

	eMedicine - Digitalis Toxicity : Article by Vinod Patel, MD
		Digitalis toxicity was well known in previous centuries, and some have suggested that the toxic visual symptoms of digitalis may have played a role in Van Gogh's use of swirling greens and yellows.
		Furthermore, the magnitude of the inotropic effect of digitalis is proportional to degree of inhibition of the enzyme.
		Incidence of digitalis toxicity has declined in recent years because of a decrease in digitalis usage, improvement in digoxin formulation with more predictable drug bioavailability, better understanding of pharmacokinetics, increasing awareness in drug-to-drug interactions, increased appreciation for factors that can increase the risk of toxicity, and availability of other drugs to treat heart failure.

		Despite improved pharmacologic knowledge, digitalis poisoning continues to be a serious problem in infants and children because of its wide availability and narrow therapeutic index.
		Digitalis increases phase 4 of the action potential in most myocardial tissue, leading to a reduction of conduction velocity with increased automaticity and ectopic activity.
