How do you take the sting out of a bee sting?
Hopefully you used a card or something similar to "flick" off the remainder of the stinger. If you were like me and simply pulled it out with tweezers, then you have injected …the full load of the venom and are in for intermittent itching and pain for a week or so. I used anti-itch cream and then periodically iced the area to cool it down. There are over the counter topical sting treatments. As for home remedies, I have used a combination of baking soda and water mixed into a paste with cigarette tobacco added, this has worked as well as anything else for me. (MORE)

What makes a stinging nettle sting?
Stinging nettle is a dioecious herbaceous perennial, 1 to 2 m (3 to 7 ft) tall in the summer and dying down to the ground in winter. It has widely spreading rhizomes and stolo…ns, which are bright yellow as are the roots. The soft green leaves are 3 to 15 cm (1 to 6 in) long and are borne oppositely on an erect wiry green stem. The leaves have a strongly serrated margin, a cordate base and an acuminate tip with a terminal leaf tooth longer than adjacent laterals. It bears small greenish or brownish 4-merous flowers in dense axillary inflorescences. The leaves and stems are very hairy with non-stinging hairs and also bear many stinging hairs (trichomes), whose tips come off when touched, transforming the hair into a needle that will inject several chemicals: acetylcholine, histamine, 5-HT or serotonin, and possibly formic acid. This mixture of chemical compounds cause a sting or paresthesia from which the species derives its common name, as well as the colloquial names burn nettle, burn weed, burn hazel. The pain and itching from a nettle sting can last from only a few minutes to as long as a week. [ citation needed ] Taxonomy The taxonomy of stinging nettles has been confused, and older sources are likely to use a variety of systematic names for these plants. Formerly, more species were recognised than are now accepted. However, there are at least five clear subspecies, some formerly classified as separate species: .
U. dioica subsp. dioica (European stinging nettle). Europe, Asia, northern Africa . .
U. dioica subsp. galeopsifolia (fen nettle or stingless nettle). Europe. (Sometimes known as Urtica galeopsifolia ) .
U. dioica subsp. afghanica . Southwestern and central Asia. (Gazaneh in Iran) .
U. dioica subsp. gansuensis . Eastern Asia (China). .
U. dioica subsp. gracilis (Ait.) Selander (American stinging nettle). North America. .
U. dioica subsp. holosericea (Nutt.) Thorne (hairy nettle). North America. Other species names formerly accepted as distinct by some authors but now regarded as synonyms of U. dioica include U. breweri, U. californica, U. cardiophylla, U. lyalli, U. major, U. procera, U. serra, U. strigosissima, U. trachycarpa , and U. viridis . Other vernacular names include tall nettle, slender nettle, California nettle, jaggy nettle, burning weed, fire weed and bull nettle (a name shared by Cnidoscolus texanus and Solanum carolinense ). Distribution .
D. urticaria : close-up of the defensive hairs .
Stinging nettles are abundant in northern Europe and much of Asia, usually found in the countryside. It is less gregarious in southern Europe and north Africa, where it is restricted by its need for moist soil. In North America it is widely distributed in Canada and the United States, where it is found in every province and state except for Hawaii and also can be found in northernmost Mexico. It grows in abundance in the Pacific Northwest, especially in places like Vashon Island (Tristin) where annual rainfall is high. In North America the stinging nettle is far less common than in northern Europe. The European subspecies has been introduced into North America as well as South America. In the UK stinging nettles have a strong association with human habitation and buildings. The presence of nettles may indicate that a building has been long abandoned. Human and animal waste may be responsible for elevated levels of phosphate and nitrogen in the soil, providing an ideal environment for stinging nettles. This seems particularly evident in Scotland where the sites of crofts razed during the Highland Clearances can still be identified. [ citation needed ] Ecology Nettles are the exclusive larval food plant for several species of butterfly, such as the Peacock Butterfly [1] or the Small Tortoiseshell, and are also eaten by the larvae of some moths including Angle Shades, Buff Ermine, Dot Moth, The Flame, The Gothic, Grey Chi, Grey Pug, Lesser Broad-bordered Yellow Underwing, Mouse Moth, Setaceous Hebrew Character and Small Angle Shades. The roots are sometimes eaten by the larva of the Ghost Moth Hepialus humuli . Medicinal uses .

As Old English Stiðe , nettle is one of the nine plants invoked in the pagan Anglo-Saxon Nine Herbs Charm , recorded in the 10th century. Nettle is believed to be a galactagogue [2] and a clinical trial has shown that the juice is diuretic in patients with congestive heart failure [ citation needed ] . Urtication, or flogging with nettles, is the process of deliberately applying stinging nettles to the skin in order to provoke inflammation. An agent thus used is known as a rubefacient (i.e. something that causes redness). This is done as a folk remedy for rheumatism, providing temporary relief from pain. [ citation needed ] The counter-irritant action to which this is often attributed can be preserved by the preparation of an alcoholic tincture which can be applied as part of a topical preparation, but not as an infusion, which drastically reduces the irritant action. Extracts can be used to treat arthritis, anemia, hay fever, kidney problems, and pain. [ citation needed ] Nettle leaf is a herb that has a long tradition of use as an adjuvant remedy in the treatment of arthritis in Germany. Nettle leaf extract contains active compounds that reduce TNF-α and other inflammatory cytokines. [3] [4] It has been demonstrated that nettle leaf lowers TNF-α levels by potently inhibiting the genetic transcription factor that activates TNF-α and IL-1B in the synovial tissue that lines the joint. [5] Nettle is used in hair shampoos to control dandruff and is said to make hair more glossy, which is why some farmers include a handful of nettles with cattle feed. [6] It is also thought nettles can ease eczema. Nettle root extracts have been extensively studied in human clinical trials as a treatment for symptoms of benign prostatic hyperplasia (BPH). These extracts have been shown to help relieve symptoms compared to placebo both by themselves and when combined with other herbal medicines. [7] Because it contains 3,4-divanillyltetrahydrofuran, certain extracts of the nettle are used by bodybuilders in an effort to increase free testosterone by occupying sex-hormone binding globulin [8] Fresh nettle is used in folk remedies to stop bleeding because of its high Vitamin K content. Meanwhile, in dry U. dioica , the Vitamin K is practically non-existent and so is used as a blood thinner. An extract from the nettle root ( Urtica dioica ) is used to alleviate symptoms of benign prostate enlargement. Nettle leaf extract, on the other hand, is what has been shown to reduce the pro-inflammatory cytokines TNF-α and IL-B1. Food .
A young red-tinted variety of American stinging nettle..
Stinging Nettle has a flavour similar to spinach when cooked and is rich in vitamins A, C, D, iron, potassium, manganese, and calcium. Young plants were harvested by Native Americans and used as a cooked plant in spring when other food plants were scarce. [9] Soaking nettles in water or cooking will remove the stinging chemicals from the plant, which allows them to be handled and eaten without incidence of stinging. After Stinging Nettle enters its flowering and seed setting stages the leaves develop gritty particles called "cystoliths", which can irritate the urinary tract. [9] Stinging nettle contains 40% protein, [ clarification needed ] which is high for a leafy green vegetable. [10] [11] [12] [ citation needed ] The young leaves are edible and make a very good pot-herb. The leaves are also dried and may then be used to make a tisane, as can also be done with the nettle's flowers. Nettles can be used in a variety of recipes, such as polenta and pesto. Nettle soup is a common use of the plant, particularly in Northern and Eastern Europe. Nettles are sometimes used in cheese making, for example in the production of Yarg [13] and as a flavouring in varieties of Gouda [14] In the UK, an annual Stinging Nettle Eating Championship draws thousands of people to Dorset, where competitors attempt to eat as much of the raw plant as possible. Competitors are given 60 cm (20 in) stalks of the plant, from which they strip the leaves and eat them. Whoever strips and eats the most stinging nettle leaves in a fixed time is the winner. The competition dates back to 1986, when two neighbouring farmers attempted to settle a dispute about who was responsible for controlling the weed. [15] In Nepal and in Kumaon region of Northern India, Stinging Nettle is known as Shishnu. It's a very popular cuisine and cooked with Indian spices. Stinging Nettle is a listed ingredient of Maynards Sports Mix, a candy sold in the United Kingdom (MORE)

Why is your bee sting stinging?
If you are asking why a bee stings, it is for protection: to defend herself (only female bees have stingers) when the bee feels attacked or when she feels her nest is being th…reatened. If you are asking why you feel a stinging sensation when a bee stings you, it is because she has embedded her stinger into whatever part of your body received the sting (your arm, or your leg, for example). The stinger needs to be removed and medicine needs to be put on the sting. There is a link below about what to do in case you are stung by a bee. (MORE)
