Medically reviewed by Debra Sullivan, Ph. We used to think that the main component was formic acid, the same compound contained in ant venom. Other chemicals contained in the stinging nettle venom, and the ones we now think are primarily responsible for the pain it induces, are histamine, acetylcholine, and serotonin.
When injected by the stinging nettle, however, it functions as an irritant, leading to pain. Acetylcholine is another neurotransmitter that can accomplish a similar effect, and you might remember histamine from previous discussions of allergies, particularly hayfever.
In the venom, histamine causes inflammation and pain. Additionally, tartaric acid and oxalic acid are two compounds, isolated in a different species of stinging nettle, which were implicated in the drawn-out effect. However, further studies could reveal that there are still gaps in our current understanding. In some countries, your immediate reaction would probably be to hunt for a dock leaf to rub on the affected area.
To many, this is almost second nature, but is it actually in any way effective? Another suggestion is that dock leafs contain a natural antihistamine, which prevent histamine in the venom from producing inflammation and pain. After a lot of hunting, the only paper I could find naming a specific compound references another paper that supposedly shows dock leaf to have high levels of chlorphenamine.
Another oft-suggested remedy is applying calamine lotion to the skin. Calamine is usually a mixture of zinc oxide and a small amount of iron III oxide, and is unsurprisingly the main ingredient in calamine lotion. Other, stranger methods of treating stings have also been suggested.
One remedy that will alleviate the pain of the sting somewhat is the use of antihistamine or corticosteroid creams. Both of these prevent the action of histamine. Currently, this is the only remedy for nettle stings for which there is concrete scientific evidence. But, even better, maybe have some antihistamine cream pre-packed as well! Don't flog yourself too much for letting this weed find its way into your garden.
You're a good gardener. Stinging nettle is a weed of damp, rich soils. Now, if only I could find some use for creeping Charlie and quackgrass, two other weeds of damp, nutrient rich soils.
