Cactus spines are modified leaves that resemble needles. Cactus may lose less water in hot and arid environments because of its needle-like adaptability. Additionally, they give out some shade and are a fantastic deterrent to animals that might try to eat them.
Some cactus feature camouflage-producing spines, which further helps to defend them from predators who could try to consume them. Less light reaches the stem of the plant because the cactus spines reflect light (reducing water loss).
What types of cactus spines are there?
Various cactus plants may have one of a few different types of cactus spines. Some spine types could be more difficult to remove and hurt more when pricked. Types of cactus spines include:
- tiny, hair-like spines (such as in genus of Cephalocereus)
- Stiffened spines (such as in Mammillaria gracilis)
- rounded spines (such as in Sclerocactus papyracanthus)
- Glochids (such as in Opuntia rufida)
- bent spines (most cacti)
One of the sorts of cactus spines that causes the most discomfort is the glochid. This is due to the glochids’ brittleness and easy skin-breaking. This makes removing them from the skin extremely difficult.
This also applies to cholla or barbed spines. They are extremely painful and easily penetrate skin and soft tissues. These cacti belong to the Opuntioideae subfamily, which also includes Chollas and Cylindropuntia.
Because they adhere to flesh, clothing, and fur with ease, cholla cacti are sometimes known as jumping chollas. They must be carefully removed from the skin since if done by hand, they would cling to the fingers.
What to do if a cactus is touched?
Cactus spines can be easily removed with a pair of tweezers if you manage to get one or two stuck in the flesh. But what if you end up being one of the unfortunate people who gets stuck with a hand, foot, or butt full of needles? Elmer’s Glue works well for this, just spread a thin layer of it over the surface.
Once the glue has had time to dry completely, allow it to sit for a while before peeling it off. Your skin-piercing needles will rise to the surface and be pulled out by the glue. If you get a good foot- or handful, you might need to repeat a number more times.
Using duct tape is a different choice that I haven’t personally tested but that has received excellent recommendations (should you be out of glue.) However, since you’ll have to apply pressure in order to trap the needles, this seems uncomfortable.
In either case, when you remove the spines, make sure to thoroughly cleanse the area with antibacterial soap. You don’t want the injury to contract an infection.
If portion of the needle does not stick out above the skin, you can find it more challenging. You could want to leave it in your skin for a few days if it isn’t hurting you. The needles are pushed to the top by the body, which makes them simpler to catch.
Call an ambulance if you experience a serious fall and become coated in needles, but in reality, it would be best to stay clear of the cacti altogether.
Is touching a cactus poisonous?
Are Cacti Toxic to People? Humans cannot be poisoned by cacti. Cacti are only harmful if you eat them, which might result in diarrhea and stomachaches. It’s advisable to avoid touching or eating cacti because some people may be allergic to their thorns.
Can you get sick from a cactus?
You may have heard that if you ever become stranded and dehydrated in the desert, a cactus may provide you with water. Although it seems like a good survival tip to keep on hand, is it really that simple? It transpires that a cactus is not essentially a freshwater basin covered in spines. In a dry environment full of thirsty creatures, such a plant would not survive for very long. In addition to their frightening spines, most cactus species further guard their spongy flesh with acids and powerful alkaloids since water is a very valuable resource in a desert. Most people find these substances to be too bitter to tolerate, and ingesting them puts a strain on the kidneys. Some cactus species’ meat can also result in temporary paralysis, vomiting, and diarrhea—none of which are helpful for your survival in a crisis. The prickly pear and one species of barrel cactus, the fishhook barrel, stand out as prominent outliers to this norm (Ferocactus wislizeni). While both of these plants are fairly unpleasant to consume raw, they contain fewer harmful compounds and could provide some hydration in an emergency. Better options include cactus fruits, however many are unpleasant to eat raw.
*Of course, all of this assumes that you are stranded in a desert in the New World with real cacti. Members of the Euphorbiaceae family, which resemble cactus plants, are poisonous and can be found in the deserts of Madagascar and southern Africa. If this plant’s milky sap gets in your eyes, it can permanently blind you and burn your skin and mucous membranes. Do not attempt to consume those.
Christopher Columbus claimed to have seen mermaids off the coast of what is now the Dominican Republic; however, they were manatees, and he described them as “not half as beautiful as how they were drawn.”
Why can touching a cactus cause pain?
Anyone who has come into contact with a jumping cholla cactus can attest to the fact that it is both excruciatingly painful and challenging to resolve because the cactus’ spines are notoriously difficult to remove.
Cactus spines have a variety of purposes, including defense and the storage of essential water in arid regions, although some are considerably more difficult to remove than others. Researchers have now determined the cause.
Microstructure Matters
The function of the spines, particularly their capacity to pierce animal skin, was tested by Stephanie Crofts and Philip Anderson of the University of Illinois on six different cactus species. Their findings, which were reported in the Proceedings of the Royal Society B, demonstrate that the microstructural characteristics that enhance a spine’s capacity to pierce flesh also raise the barrier to removal.
With their shingled, overlapping barbs, cholla and other barbed cactus spines in particular resemble porcupine quills. Compared to non-barbed spines, these barbs more easily pierce and entangle flesh.
According to Anderson in a news statement, “The barbs grab on your muscle fibers, making it tough to remove them.
The two also experimented with golden barrel, brittle prickly pear, and a few other common cactus species in addition to jumping cholla. They pierced skinless chicken breasts, hog shoulders with the skin still on, and a succession of rubbers with various densities to determine the structure of each plant after studying the spines under a scanning electron microscope to learn more about it. According to their experiments, barbed spines function as razor-sharp blades that may readily pierce skin.
According to Anderson, the cholla spine needs to be able to penetrate the target with just a mild brush in order to puncture the target efficiently. ” It must also be quite challenging to remove at the same time.

Stuck On You
Barbed spines, like cholla, emerged out of the chicken breasts with a tissue-coated exterior. The researchers believe that some of the barbs were left behind in the flesh because they did not emerge clean from the pork samples.
The plains prickly pear’s spines checked out took the most effort to remove from chicken breasts. On the other hand, cholla spines proved to be the most difficult to extract from pig tissue; tests revealed that one cholla spine was capable of hooking into flesh with sufficient force to lift half a pound of pork by the skin.
That’s both quite frightening and clever. Cholla spines also have a reproductive function. Chollas have spines that hook onto a person or animal’s muscle fibers so strongly that it frequently tears off a piece of the cactus, which is then moved to a new area and can start growing as a new plant.
Are cactus needles skin-soluble?
Maybe you’re hiking through a small desert canyon twenty miles off the beaten path. Or perhaps you take a wrong turn through your aunt’s succulent garden after two martinis at her cocktail party. Cactus spines can hurt, whether you encounter them in the wild or in a botanical garden, and if you’re not careful, the tiny, hairy ones known as glochids may even endanger your health. The best course of action is to avoid getting into contact with cactus spines, but if that is not possible, here is how to fix the problem.
Cactus spines can be divided into two categories. The majority of cacti have the thick kind, which is easiest treated like a splinter, and the glochids mentioned before, which need to be extracted using a whole other technique.
First, let’s talk about the common spines. Unless you really wail on the plant, as I did here with my bare foot, most cacti’s spines won’t come away from the plant when you brush up against them. The best approach to treat a cactus spine puncture wound that then has the decency to remain attached to its parent plant is to treat it just like you would any other scratch or puncture wound, despite how terrible it is. Ensure the cleanliness of your new piercing. In the wilderness, this might call for moist towels and a product resembling hand sanitizer. If you’re close to a plumbing system, soap and water will do the trick. After that, simply monitor the wound as it recovers to prevent infection.
It’s considerably more likely for thin-spined cacti to break off and stab your skin. Most of the time, you ought to be able to remove these by treating them like a small splinter. If you don’t have tweezers, you should use the blade of a pocketknife to scrape the spines loose. It should go without saying that you should use extreme caution when doing this.
It will be much harder to remove the spines if none of them stick out above the skin. You might be able to locate the spine with a sterile needle if it is close to the surface of a rough patch of skin, on a heel, a kneecap, or another location comparable.
You may rationally opt to leave the spine in place to dissolve gradually over a few weeks if doing so would be too similar to surgery and it isn’t causing you too much discomfort. Many individuals who frequently come into contact with cacti do precisely that. However, putting any foreign body in your skin does dramatically raise your risk of contracting an infection. Additionally, you have no idea what type of terrible stuff may have covered the spine before it became your new home, from bird feces to a decaying carcass.
The best course of action for badly lodged spines that you can’t remove on your own is to have them removed for you by a doctor, skilled First Aid professional, or other knowledgeable individual. The advantage of this is that you can ask them to check the wound for infections and assist you in keeping it clean while you recover.
There can never be just one glochid wound. A glochid that penetrates your skin most likely brought several hundred of its companions with it. Glochids make their way into your flesh to the point where their hilt would be if they had hilts, and because their shafts are barbed, it is more difficult than it should be to remove them. Glochids detach with the slightest wind.
The good news is that only a small number of cacti, including cholla and prickly pears, have glochids. There are a lot of cholla and prickly pears out there, which is bad news. The bad news is that even the best methods for getting rid of glochids on your skin only work approximately 95% of the time, leaving 5% of them behind. And when you rub that patch of skin in the wrong manner, the stupid things hurt a lot more than their size would suggest, creating pains that range from bothersome to terrible.
If you get punctured by several glochids, there is one thing you must do immediately: keep the affected area of your body away from your mouth. Unbelievably often, when someone has a patch of glochids trapped in their hand, they go for their lips and almost instinctively try to suck the irritating spines out of their skin. The risk with this is that it occasionally succeeds in sucking the glochids out of your skin and into your mouth. There, they can become lodged in your tongue, gums, or even your windpipe, where the consequences can be lethal or extremely uncomfortable.
Similarly, you should never touch your face, especially the area around your eyes.
Tweezers are your first line of defense when dealing with glochids, just as you would be with their larger, less irritable relatives. When using tweezers carefully, in bright light, with patience, and good vision, you can remove somewhat more than half of the glochids that are typically transferred during accidents. The fact that the organisms frequently fall off the plant in groups is advantageous; you may be able to remove a few dozen glochids with a single tug.
Adhesives can also be used to mass remove glochids. I’ve successfully covered the troublesome region with duct tape, ripped it off, and used it again. This effectively destroys between a third and a half of the glochids, any local hair, and sporadically the top millimeter of skin.
The best way to remove glochids appears to be a two-step procedure. With tweezers, first get rid of as many as you can. After that, wrap the damaged region in gauze and thoroughly cover it with white glue. Peel off the gauze when the glue has had time to cure. You can remove all but 5% of the glochids using a combination of the two techniques.
Unfortunately, even the most successful removal techniques frequently leave the glochids’ barbed points buried in skin. This doesn’t bother many people or simply makes them slightly uncomfortable. However, these lingering barbules can lead to extremely bothersome dermatitis, which is best treated by scraping the sores open and removing the barbules using dissecting equipment and a microscope.
It goes without saying that admiring glochids from a distance is the best course of action.
The image up top suggests one more cactus spine removal scenario: frequently enough, an entire portion of cholla will lodge in your skin and refuse to come off. It’s best to avoid the urge to use your free hand to try to pull the part away because you’ll almost surely wind up impaling it. More essential, avoid vigorously shaking the limb the cholla stem is clinging to in an attempt to remove it. The cholla has been known to come off at a high rate of speed and strike more than one person in the face.
Instead, pry the part away from you using a foreign item. A huge comb is a common item carried by desert rats who are used to live in cholla country since it is an effective tool for removing the stems of chollas by hand. If you don’t have a comb, get a clean stick—not a cactus skeleton, since those frequently still have spines attached—and use it to carefully peel the stem off by yourself with the least amount of throwing. Then look for glochid areas on your skin and prepare the tweezers and white glue.
