White Horsenettle

White horsenettle is a consumable item in Fallout: New Vegas.

Characteristics
White Horsenettle is a plant, which has, rather interestingly, managed to survive the thermonuclear apocalypse with virtually no change in morphology. The White Horsenettle is one of several dozen species of so-called "Stinging" Nettles; the plants themselves have thin, hair-like thorns along its leaves and stalks. When touched, the plant injects a compound derived from Formic Acid into the hapless unfortunate that got a nettle or two in their skin. Larger doses of nettle poisoning can cause itchiness around the wound site, inflammation, and blistering. They have a straight, tall stem and heart-shaped leaves. In maturity, tiny clusters of flowers form where the leaves and stem meet.

Like all other Mojave Wasteland plants, ripe White Horsenettles found in the wasteland will eventually regrow after being picked by the player; making them an unlimited supply of free food.

Uses
White Horsenettles are a useful plant; whilst eating them is not recommended (they have a very nasty effect on a player), they are used in several creations including several poisons, including Mother Darkness, Tremble, Silver Sting, and Bleak Venom. It is also used to tan Gecko hides, resulting in much more valuable versions, such as the (Tanned Gecko Hide, Tanned Fire Gecko Hide, and Tanned Golden Gecko Hide.

Locations
Horsenettles tend to grow near civilized areas. It can be found in large quantities near Primm (North of the fence, area containing the casino) and Goodsprings. You can also find horsenettle on the flatlands and in the ruins surrounding Boulder City. The surroundings of Lake Mead have some horsenettle growing. It can also occasionally be found on legion soldiers.

Other good locations are outside the Freeside North Gate at the nearby farm areas and under the water tower in the Crimson Caravan Company.
