Edible Uses
Edible Parts: Leaves Seed Shoots
Edible Uses:
Young shoots - cooked[105, 172]. See the notes above on toxicity. Seed - raw. A delicious nutty flavour but rather difficult to harvest[172], mainly because of their exploding seed capsules which scatter the ripe seed at the slightest touch[K].

Medicinal Uses
Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Antiseptic Diuretic Emetic Laxative
The plant is antiseptic, diuretic, strongly emetic, laxative and vulnerary[4, 9, 61]. It has been used in the treatment of stranguary and haemorrhoids[4]. The plant is occasionally used internally in the treatment of haemorrhoids and as a laxative and diuretic, but the dose must be carefully adhered to since large quantities are strongly emetic[9]. The plant is harvested at any time in the summer[9].

Cultivation details
Succeeds in any reasonably good soil[1]. Grows well in heavy clay soils. Prefers a moist well-drained humus rich soil in a cool site[200]. Self sows in areas where the minimum temperature is no lower than -15°c[200]. This plant has seed capsules that spring open forcibly as the seed ripens to eject the seed a considerable distance. The capsules are sensitive to touch even before the seed is ripe, making seed collection difficult but fun[K].

Plant Propagation
Seed - sow spring in a greenhouse. A period of cold stratification may help to improve germination rates. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. If you have sufficient seed, it is worthwhile trying an outdoor sowing in situ in the spring or the autumn[4].
