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

image showing someone using black stone1. First apply a couple of drops of water onto one surface of the 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.

Problems buying online

Following all the comments from readers asking where they can get it, in June 2017 I decided to do some research into the online sellers.

And sadly I could find nothing but problems with the main websites that claim to sell it.

For example:

jamaicanstone.com – the site redirects to malexhance.com where I couldn’t complete an order.

buyjamaicanstone.com – their order page doesn’t have a security certificate.

jamaicanblackstone.com – no security certificate on the billing details page.

jamaicanstone.org – accepts payment through Hipay, which has a terrible review score.

The moral of the story? Order this product online at your own risk!


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


  • 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.

    • 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.

  • 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.

  • 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.

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

  • 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.

  • 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 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.

    • 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.

  • 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.

    • 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.
