Jamaican Stone – Is The Strength Worth The Danger?

photo of 3 pieces of jamaican stone

Jamaican Stone is one of the more unusual ways to boost your sexual stamina that I’ve tried.

And not only is it supposed to help men last longer, but it’s often advertised as giving stronger erections too.

As with so many things in life though, the phrase ‘too good to be true’ might have to apply in this case.

It’s now banned by the United States Food and Drug Administration (FDA). This is because someone died from eating it, and the ingredients have been found by researchers to be potentially dangerous.

Having said that, it’s still a popular product in some communities, with many guys saying it works very well – as long as you use it carefully.

So in this Jamaican Stone review, you’ll find all the important information you need to know if you’re thinking about trying it.

What is it?

Jamaican Stone is sold as a natural 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 the stone from which 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, although 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.

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.

My experience

There have been no official studies or scientific research done on 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 above, though didn’t get it quite right the first time.

A common problem with desensitizing products is working out how much you need. Apply more than you need to, and you risk numbing yourself too much; too little and it won’t work.

I had an unpleasantly hot sensation which took around 15 minutes to subside after washing it off thoroughly. And 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.

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 4 hours some sellers claim.

Did it have the other effect of giving me a stronger, harder erection? Well, no not really – at least 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 a record in comparison to all other delay products I’ve tried, which wear off in around an hour on average.

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 the taste is strong and unpleasant.
  • 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 US news outlets, such as time.com, 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.

Maybe that explains the burning sensation I experienced.

Update – 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 decided to do 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.

So I’d be very cautious about buying it online if I were you.


There are alternatives which don’t present the same problems as Jamaican Stone.

So if you’re interested in trying a desensitizing product, I recommend taking a look at my overview of different desentizing sprays.

  1. 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.

      Hi Junior
      First time I’ve seen that site. Thanks for mentioning it.

  2. Hi Ethan, I see many reader ask buy at where? I try buy from JamaicanStoneSale.com
    Thats recomended.
    Because now many fake item.
    Hope can help all reader here.

    1. Hi Zha
      I know many people have asked. I just don’t want to recommend any particular online seller because I am not personally sure how legitimate they all are. But readers are welcome to share their thoughts on the sellers.

  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.

    1. Hi Ebo
      I don’t think women would agree with you! If it’s that good, I’m sure many women would be happy to know about it and ask their man to try it.

  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.

    1. 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.

    2. 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

    1. Hi Marty
      That sounds messed up! Why don’t you try something else instead of one you already had a bad experience with? Personally, if that happened to me, even the thought of using it would make my balls shrink!

    1. Hi
      To be honest, I don’t recommend any particular place because most of the websites have some issues with trustworthiness or not. You’ll have to weigh up the potential risks of the payment system and security of each site.

  6. I bought a piece of the stone in Ghana for 14 Dollars. This is too good to be true, I am at the office and she is still calling me for more action…

  7. 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 rock, and numbed it. the erection lasted for hours.the other down side was that it made reaching an orgasm extremely difficult. After a couple 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 have sense not been able to find it anywhere. 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.

    1. 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.

  8. 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.

  9. 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.

    1. Hi Will
      I’m guessing your mate didn’t explain that in his immigration interview! Sound advice on using it safely though.

        1. Hi
          You either buy it in stores in some countries, or online in most others. I can’t recommend a reliable source though at this point.

    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…

    1. 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.


        Yes you can but excessive sex will give your manhood cuts that may end up in defections. Get protected

  11. 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$.

    1. 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!

  12. Hi

    Has there’s been any update on the Jamaica stone ? Like if it’s now safe or been re checked etc

  13. black chocolate + melon juice + pineapple juice = PROVEN AND TESTED

    1. Hi Nilesh
      Considering the reported death was from someone eating jamaican stone, I would think twice about using it with oral sex. The amount transferred would probable be minimal, but it just sounds a bit risky to me. Having said that, it’s just my thought – I can’t say for sure what would happen. Perhaps some unpleasant numbing in your partner’s mouth.

  14. Please I’ve tried it and have been experiencing the numbing sensation for about a week. What should I do. Thanks

    1. 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.

  15. Hi, I do i know if i order this Jamaica store that i’ll get it? i order one before didn’t get it, so how will you assure me that if i order i’ll get it.

    1. Hi Mustafa
      I only review Jamaican Stone, I don’t sell it. So I can’t make any assurances about delivery from anyone that does sell it.

  16. Malik Waheed

    hi there i never tried this and how you sell the pill and how long to takes to deliver any side affects ?
