Jamaican Stone – Is The Strength Worth The Danger?

jamaican stoneJamaican 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 guys 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’ may unfortunately apply in this case.

It’s banned by the United States Food and Drug Administration (FDA), partly because someone died from it, and also because the ingredients are now known 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 form 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 scary 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

2. Rub the water on the stone in a circular motion until it turns into a milky colored liquid. This should take no more than a minute.

3. Gently rub that liquid onto the sensitive parts of your penis. Concentrate on the head as this has the most sensitive nerve endings.

4. 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.

5. Before you have sex wash off any excess liquid with some mild soap.

6. 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. But in the name of experimentation, that didn’t put me off.

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.

The main problem with desensitizing products in general 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 stoneIn 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.


There are alternatives which don’t present the same potential risk as Jamaican Stone. So if you’re interested in trying a desensitizing product, I highly recommend taking a look at my overview of different desentizing sprays.

  • Hello,

    Could anyone suggest if Jamaican Stone is availble to be purchased in Thailand?

    Any advise shall be greatly appreciated.

  • 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 .

    • Hi Joseph
      It sounds like maybe you just used too much and didn’t wash it off in time. Hopefully your penis will recover fully from the numbing.

  • 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

  • Please, how do i get this jamaican stone to buy. I will appreciate it if i can get the contacts of the manufacturer.

    • Hi Clemo
      There isn’t just one manufacturer, but several I think. The best thing is to look online for companies that sell it. If you do a search, you’ll find several.

    • 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?

  • 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!

  • 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$

  • Dear Ethan, I enjoyed reading your article. However, I must take the time to point out that there is only a single death reported from the use of Jamaican Black Stone. I also want to point out that the single death that occurred form the use of the Jamaican Black Stone had resulted from improper usage.

    But, while there is that single death, there are thousands who have died from the use of erectile dysfunction drugs such as Viagra. My preference is the Jamaican Black Stone, which is a herbal product that I can use topically. And what I like most about this product is that I do not have to ingest it….It does not goes inside my stomach which is a no no for me.

    • Hi Johnny
      I’m glad you enjoyed the article. Yes, you’re right in that comparatively Viagra has caused more deaths. The difference though is that Viagra is approved for use – as long as it’s used carefully and not by people with certain pre-existing heart conditions. But yes, essentially I see your point that other drugs do cause serious problems too. I think if it were only for that one death through improper use, I might not warn against Jamaican Stone so much. But the other problem of causing burning, which is very common it seems, is what makes me most concerned.

  • Hi Ethan happy new year. this great post bout premature Ejaculation. I just suggest to all reader here, can buy online via JamaicanStoneSale.com the item high quality and cheaper, because they focus for reseller. Hope can help all reader here. Keep post great info Ethan.

  • Hi
    I would like to try the black stone. I saw a few for sale on eBay, most of them based overseas but I am not sure if I can trust them . I am based in the us. Any supplier website you would recommend ?

    • Hi Ric
      I understand your concern. To be honest though, considering my for mistrust of the product generally, I avoid affiliating myself with any particular seller. Sorry!
