Impatiens pallida - Nutt.

Common Name Pale Jewelweed, Pale touch-me-not
Family Balsaminaceae
USDA hardiness 7-10
Known Hazards Regular ingestion of large quantities of these plants can be dangerous due to their high mineral content[172]. This report, which seems nonsensical, might refer to calcium oxalate. This mineral is found in I. capensis and so is probably also in other members of the genus. It can be harmful raw but is destroyed by thoroughly cooking or drying the plant[K]. People with a tendency to rheumatism, arthritis, gout, kidney stones and hyperacidity should take especial caution if including this plant in their diet[238].
Habitats Moist woodland and wet meadows, usually on calcareous soils[43].
Range Eastern N. America - Newfoundland to Saskatchewan, south to Georgia.

Edible Uses

Edible Parts: Leaves;  Seed.
Edible Uses:

Young leaves and shoots - cooked[62]. Added to sukiyaki, chow mein and other oriental dishes[183]. When used as a vegetable on their own the cooking water should be changed once or twice during the cooking[183]. Some caution is advised, see the notes on toxicity at the top of the record. Seed[62]. No more details are given but the seeds are difficult to harvest in quantity, 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.

Skin;  Stings.

The whole plant is diuretic, emetic and purgative[238]. It is only used externally, the soothing and medicinal sap is a proven remedy for nettle stings and poison ivy rash[62, 207, 222, 238, 257] and is also used in the treatment of warts, corns, ringworm and haemorrhoids[238].

Other Uses

Fungicide.

A fungicide is obtained from the plant. It is used to treat skin diseases[62]. There are no more details but it is probably obtained from the fresh juice of the plant and can be concentrated by boiling up the juice.

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]. The plant is hardy to about -5°c[238]. It should be possible to grow it as a spring-sown annual in most parts of Britain. 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].
