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.

  3. Dear Ethan,

    I have a serious problem of premature ejaculation ?. I always come very fast.

    For the first time I tried this stone. I wet my finger tip, rubbed on the stone for few seconds and applied the glue like on the tip of penis. I applied a little only.

    I waited for one minute and didn’t feel any burning sensation at all. I washed penis and went to sex, but again came fast. I don’t know what the problem is. Am I doing anything wrong or the stone is not genuine…?

    Please help me……???

    1. Hi Jaffy
      It could either be because it was a fake, but more likely it just doesn’t work for you. No desensitizing product works perfectly for 100% of guys unfortunately. So it’s sometimes a case of trial and error until you find one that works. Equally, for some guys, it’s just not the right answer full stop. So you might be better off trying to control your arousal levels naturally rather than the physical sensitivity option.

    2. Hi Jaffy, did you say you waited for just a minute and the penis for sex? No man, wait for at least after 35 min. Do not rush for sex. Relax completely. Take your mind off “the match”. I also think if No heat on the penis after you have applied the liquid and waited then NO effect. By the way any help I really need some in Ghana. tkx

  4. Hi I’m Von
    I read all the comments. The stone works better than anything I’ve ever used . I live in Atlanta Ga. I’ll like to know a retailer in Georgia or in the US.

    1. Hi Von
      Thanks for your comment. If it works for you, then great! I don’t know any specific retailers there. You’ll probably have to find a website you feel looks trustworthy.

  5. Hallo guys..

    Best Regards

    1. Hi Kamal
      Sorry you had that experience. I’m not sure myself where you can get it – perhaps some readers will have an idea for you.

    2. Sex shop in the red light district Amsterdam
      In the langeniezel and the korte niezel.
      They sell it openly


      1. Sorry Donny, I never publish people’s contact details. You would have lots of strangers contacting you! If you know a shop though, feel free to say.

    3. In Amsterdam you can buy the original blackstone at……Red Rose Novelty, Oudezijds Achterburgwal 129a, 1012 DE.

    4. I have a trust worthy friend who sells it here in the UK if this will help you

        1. Hi there
          I don’t publish people’s emails in these comments. However, if you can provide details of a shop or website Kayy that would be great.

  6. What’s the difference between Jamaican stone and Jerusalem stone . they are both called black stone right are they then the same??

    1. Hi Dichi
      I’ve never heard of Jerusalem stone as a desensitizing sex product, which to me would be the difference. Did you find a website or shop selling it as such?

  7. hi i am using this jamica stone but i used only one drop of this i having lot of burning sensation to my head of penis and where it will touch it that’s also getting burning sensation. how can i reduce this sensation immediately.

    1. Hi Mouttou
      Sorry to hear you’ve had that reaction to it. Presumably by now you’ve managed to find a way to reduce the burning. But if not, I’d get some doctor’s advice. I also wouldn’t recommend taking it again if you’ve had that reaction to it with just one drop.

  8. Bought a small stone in a sex shop in Amsterdam about 8 years ago. Works wonders. The stone is now about a quarter of its original size. I use a very small quantity of hot water in a glass and put the stone in for about 30 seconds. I then rub the stone on the head of my penis for another 30 seconds. If I wash off after 5 minutes with soap and water it works great. If I leave it on for 15 minutes it is really hard to cum… takes forever.

    1. Hi Ray
      Thanks for your comment. It’s always interesting to hear people’s stories. I think the idea is to rub it on with your hand, not directly on. That might help reduce the extra numbing!

    1. Hi Sami
      I’m not sure – search online for a distributor who sends it there. I can’t reccommend any personally though, sorry!

  9. Please I wanna ask if the jamaican stone affect semen.. can the sperms impregnate her when using jamaican stone?

      1. Hi James
        To be honest, I can’t really vouch for the legitimacy of any particular seller. Though I do know this company has been around for some time, and seems quite popular with people as others have also written to me about them. Beyond that I can’t tell you. If you decide to use them, then let me know if it works!

    hi ethan.

    i am from malaysia, the borneo side of it not the peninsular, here we have a product similar to that black jamaican, it basically do what the black jamaican can do, and also the same side effect. we call it GAMBIR SARAWAK. but it is much safer than black jamaican, and it helps with the erection, when i use it last night, i had sex an hour with my wife,i am happy i was able to make love to her that long.

    today, we will do it again, and i will try up to 2 hours this time.

    1. Hi Calelthan
      Thanks for that idea. I don’t think Gambir Sarawak has the best reputation ever, but if it works well for you, that’s all that matters.

      1. Hi im 28 years old im going to get marry I have problems erection very soon it good to use Jamaican store are gambir sarawak but in gambir sarawak website it is telling good to use gambir Sarawak then Jamaican store

        1. Hi Pasha
          I haven’t personally used Gambir Sarawak, so I can’t help much I’m afraid. However, I’d suggest looking for reviews rather than only trusting what the seller’s website says.

  11. Hi Ethan,
    When I was in my 30’s my friends and self used it and no one complained about it other than the burning sensation and everybody said that they lasted much longer. The same for myself.

    But whilst in Holland I saw it being advertised for sale, but they had sold out of it. The owner of the store said that it can cause cancer and therefore I have never used it again.

    My friends and self only stopped using as we could not purchase it any more, I have been to Jamaica several times in the last two years and can not get it.

    Finally can you email me and tell me Where did you get yours from?

    1. Hi Dunz
      That’s curious about the owner stopping selling it because of the risk of cancer!
      I haven’t bought it for some time now, and when I did I ordered it online from a wholesalers. My advice would be to google it and check out the top few sites selling it and make a judgment call yourself on how trustworthy they seem.

  12. hi there,
    i bought it from Panama,right now. but im still not clear to use this black stone properly and correct amount to apply. one more things is to apply on the penis or penis head?
    Dear Ethan, could u reply to me clearly?

    Many thanks

    1. Hi Paing

      Ok, so do this:
      1) put a little water on the stone and rub it lightly with your fingers until a kind of film/residue appears.
      2) take that residue and rub it onto the head of your penis (not inside the opening though).
      3) After 5-10 minutes wash it off, wash your hands well also with soap.
      4) If you feel a hot sensation, you know it’s working and can start having sex.

      Hope that helps

  13. Hello, ethan green!
    Please how can I access Jamaica stone am from Nigeria…

    1. Hi gago
      I’m not sure. You wold have to search online for a distributor either in your country, or abroad and ask them directly if they send to your country.



    Hiya readers, I need advice on this because I was given a Jamaican stone by a friend and apparently it is illegal to have it in your possession according to the Army because it contains bufetaine. Is it Illegal in the United Kingdom. Army trying to charge me for it.

    1. Hi Prof Liquid

      Sorry to hear you’re in such trouble! As far as I’m aware, Jamaican Stone isn’t illegal in the UK. But bufotenin is a class A drug. So presumably if you have some as part of another product, it might be considered illegal. To be honest though, I’ve not heard of any cases like yours. Perhaps one of the other readers following these comments will be able to shed more light on it.

  15. Hello Ethan,
    I found your review while looking to find out if Jamaican stone is poisonous. Your review is very informative thank you for it. I have tried it and it made me last for hours. All I needed was some energy drink to keep me firing. Jamaican Stone and other similar products don’t keep you hard or bigger like sellers say. They only reduce over-sensitivity so you don’t come quickly. The rest is in the mind, how turned on you are and how sexy your partner might be, etc. As long as you have something to keep you turned on, you can ride on for a while.
    Let’s also note that we react to things differently, hence our different experiences. Fortunately, I’m Black, so even if my penis turns red, I can’t tell. It gives some uncomfortable feeling, though. Especially if you keep it on for too long. It remains one of the best numbing agent I’ve ever used. I also feel its effects after 24hrs sometimes.

    1. Hi Kallu

      Thanks for your comment, and it’s always good to hear from people who’ve had good experiences as well as bad. Thanks for adding the info. about it not helping with all the things sellers say it does. That’s my belief as well – that really, it’s a numbing agent and no more. And you’re absolutely right about people having different experiences. That’s one reason why finding a good desensitizing product needs a bit of trial and error – albeit carefully!
