The plant is primarily cultivated for the production of bast fiber from the stem. The fiber may be used as a substitute for jute in making burlap. Hibiscus, specifical roselle, has been used in folk medicine as a diuretic and mild laxative. The red calyces of the plant are increasingly exported to the United States and Europe, particularly Germany, where they are used as food colorings. It can be found in markets (as flowers or syrup) in places, such as France, where there are Senegalese immigrant communities. The green leaves are used like a spicy version of spinach. They give flavor to the Senegalese fish and rice dish thieboudienne. Proper records are not kept, but the Senegalese government estimates national production and consumption at 700 t (770 short tons) per year. In Burma, their green leaves are the main ingredient in chin baung kyaw curry.
Centaurea cyanus, commonly known as cornflower or bachelor's button, is an annual flowering plant in the family Asteraceae, native to Europe. In the past it often grew as a weed in cornfields (in the broad sense of corn, referring to grains, such as wheat, barley, rye, or oats), hence its name. It is now endangered in its native habitat by agricultural intensification, particularly over-use of herbicides, destroying its habitat. It is also, however, through introduction as an ornamental plant in gardens and a seed contaminant in crop seeds, now naturalised in many other parts of the world, including North America and parts of Australia.

Tagetes is a genus of annual or perennial, mostly herbaceous plants in the sunflower family (Asteraceae). It was described as a genus by Carl Linnaeus in 1753. The genus is native to North and South America, but some species have become naturalized around the world. One species, T. minuta, is considered a noxious invasive plant in some areas.

Matricaria chamomilla (synonym: Matricaria recutita), commonly known as chamomile (also spelled camomile), Italian camomilla, German chamomile, Hungarian chamomile (kamilla), wild chamomile or scented mayweed, is an annual plant of the composite family Asteraceae. M. chamomilla is the most popular source of the herbal product chamomile, although other species are also used as chamomile.

Stinging nettle redirects here. For the Australian plant, see Urtica incisa. For other plants that sting, see Stinging plant with stinging hairs. Urtica dioica, often known as common nettle, stinging nettle (although not all plants of this species sting) or nettle leaf, or just a nettle or stinger, is a herbaceous perennial flowering plant in the family Urticaceae. Originally native to Europe, much of temperate Asia and western North Africa, it is now found worldwide, including New Zealand and North America. The species is divided into six subspecies, five of which have many hollow stinging hairs called trichomes on the leaves and stems, which act like hypodermic needles, injecting histamine and other chemicals that produce a stinging sensation upon contact (contact urticaria, a form or contact dermatitis). The plant has a long history of use as a source for traditional medicine, food, tea, and textile raw material in ancient societies.

Citronella grass (Cymbopogon nardus and Cymbopogon winterianus) grow to about 2 m (6.6 ft) and have magenta-colored base stems. These species are used for the production of citronella oil, which is used in soaps, as an insect repellent (especially mosquitoes) in insect sprays and candles, and in aromatherapy. The principal chemical constituents of citronella, geraniol and citronellol, are antiseptics, hence their use in household disinfectants and soaps. Besides oil production, citronella grass is also used for culinary purposes, as a flavoring. East Indian lemongrass (Cymbopogon flexuosus), also called Cochin grass or Malabar grass, is native to Cambodia, Vietnam, Laos, India, Sri Lanka, Burma, and Thailand, while West Indian lemongrass (Cymbopogon citratus) is native to maritime Southeast Asia. While both can be used interchangeably, C. citratus is more suitable for cooking. In India, C. citratus is used both as a medical herb and in perfumes. C. citratus is consumed as a tea for anxiety in Brazilian folk medicine, but a study in humans found no effect. The tea caused a recurrence of contact dermatitis in one case.

M. oleifera is a fast-growing, deciduous tree that can reach a height of 10 -12 m (32- 40 ft) and trunk diameter of 45 cm (1.5 ft). The bark has a whitish-grey colour and is surrounded by thick cork. Young shoots have purplish or greenish-white, hairy bark. The tree has an open crown of drooping, fragile branches and the leaves build up a feathery foliage of tripinnate leaves. The flowers are fragrant and hermaphroditic, surrounded by five unequal, thinly veined, yellowish-white petals. The flowers are about 1.0 - 1.5 cm (1/2) long and 2.0 cm (3/4) broad. They grow on slender, hairy stalks in spreading or drooping flower clusters which have a length of 10 -25 cm. Flowering begins within the first six months after planting. In seasonally cool regions, flowering only occurs once a year between April and June. In more constant seasonal temperatures and with constant rainfall, flowering can happen twice or even all year-round. The fruit is a hanging, three-sided brown capsule of 20 - 45 cm size which holds dark brown, globular seeds with a diameter around 1 cm. The seeds have three whitish papery wings and are dispersed by wind and water. In cultivation, it is often cut back annually to 1 - 2 m (3 - 6 ft) and allowed to regrow so the pods and leaves remain within arm' s reach.
