Family: Balsaminaceae
Genus: Impatiens
Kingdom: Planta
Order: Ericales

Common Names: Impatiens, Jewelweed, Touch-me-not, Snapweed
Part Used: Herb.
Habitat: Members of the genus Impatiens are found widely distributed in the north temperate zone and in South Africa, but the majority are natives of the mountains of tropical Asia and Africa. It grows in lowlying, damp, rather rich soil, beside streams and in similar damp localities.
Description:
Some species are annual plants and produce flowers from early summer until the first frost, while perennial species, found in milder climates, can flower all year. Regardless of their lifespan, the largest impatiens grow up to about 2 meters (about 7 feet) tall, but most are less than half as tall. The stems somewhat translucent, the foliage showing a brilliant silvery surface when immersed in water, which will not adhere to the surface. The leaves are entire and shiny; their upperside has a thick, water-repellent cuticula that gives them a greasy feel. Particularly on the underside of the leaves, tiny air bubbles are trapped over and under the leaf surface, giving them a silvery sheen that becomes pronounced when they are held under water.They are thin, ovate oval, more or less toothed, of a tender green colour.

The flowers, up to 2–3 cm, around 1 inch long, in most species are made up by a shoe- or horn-shaped spur for the most part, with at least the upper petals insignificant by comparison; some have a prominent labellum though, allowing pollinators to land. Others, like the busy lizzie (I. walleriana), have flattened flowers with large petals and just a tiny spur that appear somewhat similar to those of violets (Viola), an unrelated genus. A few Impatiens species have flowers intermediate between the two basic types.The oblong capsules of both species when ripe explode under the slightest disturbance, scattering the seeds widely. Most of the popular names refer to this peculiarity, others to the shape of the flowers.
The slipper-shaped, yellow flowers, in bloom from July to September, have long recurved tails, those of the first-named species being of a uniform pale-yellow, those of the second species, orange-yellow, crowded with dark spots, hence its common name of Spotted-touch-me-not.
Constituents: Impatiens contain 2-methoxy-1,4-naphthoquinone, an anti-inflammatory and fungicide naphthoquinone that is an active ingredient in some formulations of Preparation H.
Medicinal Uses:
North American impatiens have been used as herbal remedies for the treatment of bee stings, insect bites, and stinging nettle (Urtica dioica) rashes. They are also used after poison ivy (Toxicodendron radicans) contact to prevent a rash from developing. The efficacy of orange jewelweed (I. capensis) and yellow jewelweed (I. pallida) in preventing poison ivy contact dermatitis has been studied, with conflicting results. A study in 1958 found that Impatiens biflora was an effective alternative to standard treatment for dermatitis caused by contact with sumac, while later studies found that the species had no antipruritic effects after the rash has developed. Researchers reviewing these contradictions state that potential reason for these conflicts include the method of preparation and timing of application. A 2012 study found that while an extract of orange jewelweed and garden jewelweed (I. balsamina) was not effective in reducing contact dermatitis, a mash of the plants applied topically decreased it.
Impatiens glandulifera is one of the Bach flower remedies, flower extracts used as herbal remedies for physical and emotional problems. It is included in the “Rescue Remedy” or “Five Flower Remedy”, a potion touted as a treatment for acute anxiety and which is supposed to be protective in stressful situations. Studies have found no difference between the effect of the potion and that of a placebo.
All Impatiens taste bitter and seem to be slightly toxic upon ingestion, causing intestinal ailments like vomiting and diarrhea. The toxic compounds have not been identified but are probably the same as those responsible for the bitter taste, likely might be glycosides or alkaloids.
?-Parinaric acid, a polyunsaturated fatty acid discovered in the seeds of the makita tree (Atuna racemosa racemosa), is together with linolenic acid the predominant component of the seed fat of garden jewelweed (I. balsamina), and perhaps other species of Impatiens. This is interesting from a phylogenetic perspective, because the makita tree is a member of the Chrysobalanaceae in a lineage of eudicots entirely distinct from the balsams.
Certain jewelweeds, including the garden jewelweed contain the naphthoquinone lawsone, a dye that is also found in henna (Lawsonia inermis) and is also the hair coloring and skin coloring agent in mehndi. In ancient China, Impatiens petals mashed with rose and orchid petals and alum were used as nail polish: leaving the mixture on the nails for some hours colored them pink or reddish.
Impatiens has been listed as one of the 38 plants that are used to prepare Bach flower remedies, a kind of alternative medicine promoted for its effect on health. However according to Cancer Research UK, “there is no scientific evidence to prove that flower remedies can control, cure or prevent any type of disease, including cancer”
Other Uses: A yellow dye has been made from the flowers.
