A toxic principle is present in very small quantities in the plant[14][15][3][5][13]. It is poorly absorbed so poisoning is unlikely[13].

Pheasant's eye has a long history of medicinal use and is still retained in the Pharmacopoeias of several European countries[9]. The plant contains cardiac glycosides similar to those found in the foxglove (Digitalis purpurea)[8]. These substances improve the heart's efficiency, increasing its output at the same time as slowing its rate[8]. It also has a sedative action and so is generally prescribed for patients whose hearts are beating too fast or irregularly[8]. The herb is not often prescribed, however, due to irregular absorption[9]. The herb is cardiotonic, diuretic, sedative and vasoconstrictor[10][14][15][3][11][7]. It has sometimes been used internally as a cardiotonic with success where the better known foxglove (Digitalis purpurea) has failed - especially where there is also kidney disease[10]. The herb is also used in the treatment of low blood pressure and its strong diuretic action can be used to counter water retention[8]. It is included in many proprietary medicines, especially since its effects are not cumulative[7]. The plants are harvested every third year as they come into flower[14], they are dried for use in tinctures and liquid extracts[7]. The herb does not store well so stocks should be replaced every year[7]. Use with great caution[15], see the notes above on toxicity. The plant is used in homeopathy as a treatment for angina[8].

Propagation
This section contains historical Plants For A Future notes marked noncommercial.
Seed - best sown in a cold frame as soon as it is ripe or else it can be slow and erratic to germinate[6][7]. Sow the seed in partial shade in rich soil in September or March[2]. Prick out the seedlings when they are large enough to handle and grow them on in the cold frame for their first season. Plant out when dormant in the autumn[K]. Division in early spring or in autumn. The divisions can be difficult to establish[6], so it is probably best to pot them up and keep them in a cold frame or greenhouse until they are growing away well.
Cultivation
This section contains historical Plants For A Future notes marked noncommercial.
Grows well in any ordinary garden soil that is not too heavy[1]. Prefers a moist well-drained soil in sun or semi-shade[10][6]. Easily grown in a very well-drained rather dry soil in sun or part shade[4]. Plants flower better when growing in a sunny position[9]. This plant is adored by slugs and is therefore very difficult to grow in the open garden where slugs are common[4]. A very ornamental plant[1], it is rather rare in the wild so only cultivated plants should be harvested[14]. A greedy plant inhibiting the growth of nearby plants, especially legumes[12].
