Medicinal uses(Warning!)

The Grecian foxglove is a widely used herbal medicine with a recognised stimulatory effect upon the heart. It is also used in allopathic medicine as the main source of the cardiac glycosides that are used in the treatment of heart complaints[3][4]. It has a profound tonic effect upon a diseased heart, enabling the heart to beat more slowly, powerfully and regularly without requiring more oxygen[4]. At the same time it stimulates the flow of urine which lowers the volume of the blood and lessens the load on the heart[4]. The plant contains cardiac glycosides (including digoxin, digitoxin and lanatosides). Digitoxin rapidly strengthens the heartbeat but is excreted very slowly. Digoxin is therefore preferred as a long-term medication[4].

The leaves are cardiac, diuretic, stimulant and tonic[5][6][7][8][9]. The leaves should only be harvested from plants in their second year of growth, picked when the flowering spike has grown and about two thirds of the flowers have opened[5]. Harvested at other times, there is less of the medically active alkaloid present[5]. The seed has also been used in the past[5]. The leaves also have a very beneficial effect on the kidneys, they are strongly diuretic and are used with benefit in the treatment of dropsy[5]. Great care should be exercised in the use of this plant, the therapeutic dose is very close to the lethal dose[10]. Their use should always be supervised by a qualified practitioner since in excess they cause nausea, vomiting, slow pulse, visual disturbance, anorexia and fainting[3]. See also the notes above on toxicity.

A homeopathic remedy is made from the leaves[6]. It is used in the treatment of cardiac disorders[6].

Cultivation

An easily grown plant, succeeding in ordinary garden soil, especially if it is rich in organic matter[12]. It prefers a neutral to acid soil[3] and also succeeds in dry soils and, once established, is drought tolerant[13][14]. It prefers semi-shade but succeeds in full sun if the soil is moist[13][15].

The Grecian foxglove is cultivated for the medicinally active glycosides that are contained in the leaves[3]. This species is preferred over D. purpurea as a source of glycosides for the pharmaceutical industry[3]. Plants are either biennial or short-lived perennials[3]. Members of this genus are rarely if ever troubled by browsing deer or rabbits[16].

This species can develop crown rot and root rot when growing in damp conditions[3].
