Jamaican Stone – Is The Strength Worth The Danger?

Jamaican Stone is one of the more unusual ways to last longer during sex that I’ve tried.

Not only is it marketed as a way to have longer sex, but it’s often advertised as giving stronger erection too. However, the phrase ‘too good to be true’ might apply in this case.

It was banned by the United States Food and Drug Administration after someone died from eating it, and the ingredients have been found by researchers to be potentially dangerous (more on that below).

Having said that, it’s still a popular product in a few communities around the world, where some men swear by its potency.

In this Jamaican Stone review, I’ll cover both my experience using it and some useful background information about the safety concerns.

What is Jamaican Stone?

Jamaican Stone is sold as a sexual performance enhancer. It’s said to be harvested from the tree sap of a tree native to Jamaica and some other Caribbean Islands.

It’s then molded into a block/stone shape, like the ones you can see in the image above. The standard size is between 0.5 and 1 inches.

It’s also known as Jamaican Black Stone due to the color of the finished product, though it’s possible to find it in other forms, such as drops or gels.

Strangely, nobody seems to know the name of the tree it comes from. It doesn’t say on the packet, and no supplier website mentions the name.

And here’s the worrying part – after it caused a death, it was reported that some versions contain toad venom from the Bufo genus.

Apparently, both the toad venom and the tree sap contain chemicals known as bufadienolides, which can disrupt the normal rhythm of the heart. So no matter where it comes from, it doesn’t exactly seem the safest option.

My experience using Jamaican Stone

I couldn’t find any scientific research into the effectiveness of Jamaica stone for premature ejaculation, so I was a little in the dark when testing it.

I ordered it online and it arrived a week later in an unmarked packet. I followed the instructions, but I don’t think I applied it correctly the first time using it.

A common problem with desensitizing products is working out how much you need. If you apply too much, you risk numbing yourself to the point of feeling nothing or having trouble getting an erection. On the other hand, if you use too little, it might not work at all.

Burning sensation

I had an unpleasantly hot sensation which took around 15 minutes to subside after washing it off thoroughly. It probably took another 30 minutes for the tingling sensation to go away completely.

The second time, I was more careful and just rubbed a couple of small drops on. This time there was still a hot tingling sensation, which again took a while to subside, but it was more tolerable.

It seems to take about 10 minutes to have a noticeable effect, but 20 to be at the maximum desensitizing potential.

Good numbing, but no change in erection strength

The numbing effect was definitely effective, and there’s no doubt that using Jamaican Stone allowed me to have sex for longer. However, it wasn’t as long as the four hours some sellers claim.

Did it have the other effect of giving me a stronger, harder erection? Not as far as I could tell. Maybe that part is a marketing gimmick, or maybe it just didn’t work on this occasion.

The numbing did last for several hours, which was much longer than most other delay products I’ve tried, which tend to wear off in a couple of hours.

I tested it a few more times and had a reasonably good improvement to my lasting time during sex each time I used it. So on the whole, it did what it was supposed to do, at least in terms of helping delay ejaculation.

I’d say the effect was similar to other desensitizing products, like those containing lidocaine. So considering the potential risks of Jamaican Stone, I’d personally prefer to stick with a delay spray instead.

Further information

How to use Jamaican stone

  • Apply a couple of drops of water onto one surface of the stone.
  • Rub the water on the stone in a circular motion until it turns into a milky colored liquid.
  • Gently rub that liquid onto the sensitive parts of your penis. Concentrate on the head as this has the most sensitive nerve endings.
  • You’ll need to test exactly how long you need to wait before having sex. It could be anything from 10 to 30 minutes, so some experimenting is needed.
  • Before you have sex wash off any excess liquid with some mild soap.
  • Dry the stone and store it. It can last for several months if you care for it properly.

Possible issues and side effects

  • The main side effect is the burning sensation if you put too much on.
  • Even when you get the amount right, you still have to put up with a hot tingling sensation.
  • It’s not a good idea to use Jamaican Stone during oral sex because of the dangers of eating it. It also has an unpleasant taste.
  • The numbing sensation is strong, so could reduce the pleasure of sex.
  • The risk of serious harm – see the following section.

Death reported in the news

jamaican black stone

In 2008, many U.S. news outlets (such as ABC), reported that the New York health department was warning people not to use Jamaican Stone. This was apparently because a man died after eating it.

The warning also reported that similar versions were behind poisonings and deaths in the 1990s. Obviously, it’s not meant to be eaten, but they do further warn that even applying it to the skin can be harmful.

In 2017, researchers published a report of a case of a man who died of heart complications after ingesting the stone.

Some clarity regarding the ingredients

In 2017, Spanish researchers undertook a rigorous scientific analysis of Jamaican Stone to identify the exact ingredients.

They concluded that it has toxic ingredients and described it as a ‘dangerous aphrodisiac’. You can read their full research article here.

Problems buying online

Following all the comments from readers asking where they can get it, I did some research into the online sellers.

I encountered one problem after another, mainly with security warnings about the websites and payment systems with low review ratings.

My personal view is that this product should be avoided, especially as there are safer alternatives.


There are alternatives that don’t present the same problems as Jamaican Stone. If you’re interested in trying a desensitizing product, I recommend taking a look at my overview of delay sprays.

  1. Hi Ethan.

    After applying it, how long should it take before I wash it off?

    And if am washing it off, should I wash it off thoroughly?

    • Hi Kwesi
      I would leave it a few minutes to soak in, then wash. If there is too much liquid at the start, then just wipe it off and then wait before washing better.

  2. Hey guys, I’ve recently purchased one of this item from morrisonsintl.com, came in like about 7 days, The product works I’m not sure about that 4 hours lasting time but it significantly improves my sex life. Be aware that this product is not to be used when participating in oral sex.

  3. The best ever I can recommend anyone to go for. My wife loves my sex life now.
    I believe it is men’s number one secret and must keep it from women.

  4. Just got a tiny piece of it today. Gonna try it with my wife tonight. I hope nothing bad will happen. Does washing it thouroughly makes the effect lesser? We always loved to do oral. I guess that would be a problem.

    • Hi Joseph
      All the best with it! I think washing well after using any desensitizing product is generally a good idea, just to be one the safe side. But really, the best way to reduce the effect is to put less on in the first place.

    • I Have tried it. It does numb a lot. Does not improve erection at all, I would probably say contrary.
      I washed it several times with soap, and for hours the burning stayed. I washed my hands 4-6 times and still felt it on my lips (numbing – I do not recommend oral sex). Also my wife complained about a burning sensation still after I washed it with loads of soap and water. Not sure if this is normal but it is something to think about.

  5. I’ve had a couple of pieces for a few years now and was thinking of using it again.. Pretty sure last time i took the top layer of skin off the head of my old boy due to the burning from the stone, not from hitting the missus unfortunately.. so just be wary on the amount you slap on and how long you leave it for before washing off or you to could be peeling layers..lol

  6. The best thing I ever used. The drawback was the burning sensation. I experienced the strongest erection and the longest sex I ever had. it made my penis swell up, and get hard as a rock, and numbed it. the erection lasted for hours. another downside was that it made reaching an orgasm extremely difficult. After a couple of hours, I took a break hoping to lose the erection and it would not go away. after a couple times of using it, my wife threw it way complaining of a sore vagina and aching body from excessive hours of sex.but then after a couple weeks of normal sex, she told me to get another one. When I went back to Adam and eves to buy it, it was no longer available. I think it’s safe to use as long as you use some common sense. Like not eating it. The only side effects I experienced was a sore penis and sore aching body from hours of sex.

    • Hi Doug
      Thanks for sharing your experience. Do you know what it was about it that gave you the stronger erection though? As far as I understand it, there’s nothing in the ingredients that can do that.

  7. I’ve been using this product for more than 2 decades and I got respect from you know who. If you use too much and it’s burning: just rub your penis with any toothpaste and seconds the burning is gone.

  8. The Stone is one of the best apart from China Brush. My friend actually got his British Passport for banging the Mrs… cudos to the Stone!. It work magic if you use it safely. Never swallow it and make sure you wash the willy really well if you are not bagging up. Some women can still feel the burning sensation even after a thorough wash.

  9. i got some in the 90s and the guy told me u only put on the top ring of the penis, let set five to ten min, wash off excess, you only need just a little bit in right place, just on top of the rim of the penis head, i mean not much. the trick is not how much but where and how long left on before washing off with just water, 5 minutes was ALWAYS long enough for me but make sure u wash off, don’t want her numb, lol…

    • Hi there
      Thanks for sharing your experience and advice about using it. I think with all these kinds of products, the key is all 3 factors – how much, where to apply it, and how long to leave it on.

  10. Okay so before my first time of use, I came to this article to read carefully before use. Been using it for a month now. And she never gets enough of me. She calls me Conan, lol.

    I personally recommend to anyone who wanna impress that girl. Read well on how to use it. And you will be just fine. Good luck. Im from Ghana and its quite expensive here. I very little tinny piece of it cost 7$.

    • Hi Straw
      Thanks for sharing your experience. There’s no question that it can help some men – turn you into Conan as you say! Just be careful with it!

    • Hi Abed
      Sorry to hear you had that experience!
      If it’s still feeling numb when you read this reply, then I would definitely speak to your doctor about it.
      I hope you’re ok now though.

  11. Hello … many many years ago … maybe 25 yrs My husband returned from the Caribbean with this stone and it does the job. I was just remembering the product and decided to look it up online. Hoping to find a source for this product.

    • Hi Rick
      Some sellers claim it might, but it’s not it’s main purpose. Generally products that help with PE by desensitizing aren’t the best if you have erection problems, so I’m skeptical it can help with that.

    • nope it does not help erectile dysfunction, if they told you yes they lied for marketing. i use it all the time, and it doesnt keep you hard, you will need to purchase something else for getting and staying hard

  12. I’ve used this product for a year. it works. I’m mad as hell that the store i bought it from doesn’t sell it anymore. after using china brush for years this product is better. yeah, it stings but you get used to it after you establish your personal dosage. mine stone lasted a year. i preferred to apply mine at least 2 hours b4 sex. for me it gave me the performance i desired. I was able to have sex with my woman on a consistent basis. it’s even better if you are physically active in other aspects of life also. now that someone provided a supplier i can resume.

  13. Hi Ethan
    Just wanted to ask a stupid question
    After applying Jamaican stone, can one have sex without condom. Like is it ok for the other person (wife / girl friend )

    • Hi there
      That’s actually a very good question. I think it’s fine as long as you make sure you wait a while and wash off any excess before having sex, to make sure there’s no transference to them.

    • Yes you can have sex without condom with wife girlfriend whoever, just afer 30 mins make sure wash it off with soap and water

  14. Been using product for years it’s the best last longer than any product in market if get it right can last 45 mins and more resercher must say not good cause making other expensive products look bad for $10 and get 45 min of fun well worth it .

    • Hi Badshah
      Well, I don’t think the Spanish researchers I mentioned had a reason to rubbish it. They would also have fallen into disrepute if they simply lied about the ingredients, so I doubt they made that up.

  15. Bought from the first website suggested before reading the reviews. Ordered to Spain and it arrived within 5 business days.

    First tried it and I applied to much, little bit of a burning sensation which hasn’t gone away yet (applied 1,5h ago) little bit annoying but my own fault. As regards for the stronger erections it’s not the case but I’ve had sex successfully for over 30minutes and not been able to finish which is my intention as I usually last anywhere between 1-3 minutes. I’d rate this as a sucess.

  16. Thanks for the advice about ordering it Ethan. I’ve also looked at some sites for delivery and am suspicious of them. Time to look elsewhere I think.

  17. i’ve been using the Jamaican Stone for a few years and it’s been wonderful. You should only leave the milky cream on your penis for about 15-20min tops then rinse it off good with soap and water. If you wait around an hour before having sex, after rinsing, you’ll last the perfect amount of time (long enough to change positions, confident pumps, and have your mate happy but not too long to never climax). I’ve made the mistake and left it on for over a 1/2 hour before rinsing and that will leave you feeling quite numb and you may take FOREVER to orgasm. Also if you rinse off your penis good and wait around an hour, your mate can give you oral and she/he won’t taste a thing. Hope this helps.

  18. I used the stone, on the recommendation of a Jamaican friend, back in 1994. It worked like a charm, no side-effects. The girl whom I was screwing on the side immensely enjoyed anal and so, being 32 at the time, I knew I needed all the help I could get! Long story short, during one encounter, we did it non-stop for nearly an hour. I thought my heart would give out before my johnson would! I actually had to take a break and go wash it off in order to finally come. While it never harmed me in any way, I don’t know that it doesn’t possess some potentially harmful side-effects for other guys.

    • Hi Bill
      Thanks for sharing your experience. There’s no denying the evidence that it seems to help some guys, as you so graphically illustrate! It’s just the risks that are the worry.

  19. I tried it several years back and just as the direction states rub it til its milky and rub it on the tip of your penis and let it dry then wipe it off with soap. Avoid oral sex it can burn the mouth. But it’s does give you stamina and no feeling on the tip of the penis. So don’t expect to reach your climax, cause it not going to happen. So if you want a first impression that the route to go. I’m a living witness.

  20. Hello, please I used the Jamaican stone as to rub on the tip of the penis, but stay like an hour before washing it off, that was the direction I got from a friend that gave it to me in Paris , so after washing I did good , but refused to wear off , I feel heavy and dead at the tip of my penis. But it works . The only issue now to release me .

  21. Hmmmmm.I was once told by a friends that I can prevent ur penis from erecting when it been used too much meaning u will bee impotent

  22. 1. Don’t eat it (duh!)
    2. Don’t leave it on for more than 15 minutes the first time you try it out
    3. Everyone’s skin has a different level of sensitivity; start small and for shorter periods until you find what works best for you.
    4. If you leave it on too long, you get excessively desensitized and sex becomes boring anyway. You clearly want to enjoy sex while pleasing your partner right?

  23. Black stone is simply amazing, I have been using it for the last 20 years and all I can say is? One can keep on going for 2/3 hours, women enjoy the stamina and will always return for more.
    I got mine from Antigua.

    • Hi there
      Thanks for sharing that – it’s good to hear from guys and their experience of Jamaican Stone. I know many readers say good things about it, even if some don’t. It all points to it being a personal choice and a bit of a gamble!

  24. i can confirm its ok. It’s not a daily usage affair, its just good once in a while to feel like superman and keep her thighs hot

    • Hi Gary
      Well, some claim it can help with erection strength, but really it’s purpose is to help with lasting longer during sex. You can apply it before or after getting an erection – it will still work the same.

    • I bought this from a Jamaican 4 years ago in Texas. Wow. Got home put it under water with thumb middle and index fingers for about 30 seconds. Next rub only your three fingers around the helmet of penis about 3-4 circles. You will not come but she will pull out her check book. Yes very powerful hard on insane. I used it 2 times a week for a year. Do not rub up to ten circles as I did cause I didn’t believe. Man it was numb. Best stuff ever. Every Jamaican has the wood. Look up a restaurant or something but by it from them. It’s very important family stone Enjoy. That stone will last 2 -3 years 10$

      • Let’s say if I use it today and go for like 30 minutes sex, and I don’t use it the next time I have sex, will I last long enough like I did when I applied it?

        • Hi Kwesi
          It depends how long it is before the next time. If it’s an hour or two later, you might still find it works. If it’s 2 days later, then no, probably not.

  25. Gents,
    I have purchased this on E Bay and it took a while to reach me but, I did get it. And I also purchased some a few weeks ago while in Jamaica. This stuff is great !! I have been using the stone for a few years now.

  26. Hey I am from Jamaica and I came across this blog because I wanted to know if what was doing was ok well I think am a bit more clearer on the matter. Used stone a couple times, #BestSex lol. Dusk till dawn
