What is Spilanthes Acmella?

If you are a man over the age of 30 – 40, you have probably noticed changes in the way you feel overall, as you get older.

There are many changes that our bodies go through as we get older. When a boy goes through childhood and arrives at puberty, the levels of testosterone being produced increase considerably.

I am sure you know that women also have testosterone. Theirs are just in much smaller amounts than men. And of course, men also have estrogen, just like women, but in a much smaller amount, as long as things are working correctly.

Both men and women need to maintain the proper hormone balance in order to look and feel great and to even maintain a good attitude.

Testosterone is responsible for males for many of their common characteristics, including body hair, physical strength, and muscle mass, a deep voice, enhanced libido, aggressiveness, and higher energy levels. After the age of 30, the testosterone production in your body begins to decline at a rate of 1 – 1.5% per year. As you age and your testosterone level decreases naturally, this can lead to a loss of muscle mass, strength, stamina, energy levels, body hair, lower libido and so much more.

In other articles on my site, I have discussed many natural herbs that will increase your testosterone levels. Today, I want to talk about a rising star in the supplement world that could become the new king in testosterone boosting supplements. As of today, it is only available by itself, not in any testosterone boosting supplement formulas.

This interesting potential testosterone boosting supplement ingredient is called Spilanthes Acmella. What is Spilanthes Acmella and what will it do for my low testosterone levels?

What is Spilanthes Acmella?

Spilanthes is a flowering herbaceous plant that is part of the daisy family. It is very popular in traditional and Ayurvedic medicine throughout Asia, South America, and India. The leaves can be and are used for food sources. In Brazil, it is used as an ingredient in salads because of its aphrodisiac qualities. The flowers of Spilanthes also helped the plant to be nicknamed, the “toothache plant”, because of its properties for numbing and pain-relieving, especially when it comes to your teeth and gums. Because Spilanthes also has been shown to stimulate your taste and improve your saliva flow, it is thought that it could help with the side effects caused by some cancer treatments like dry mouth, mouth sores, and inflammation.

This interesting herb is still in the preliminary stages of research, with not much human evidence. More on this later in this article.

Spilanthes has been found to increase testosterone, Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH), but currently, this is one study and was only done on rats. More on that later in this article. The results of this study were very impressive for us men!

Is Spilanthes Acmella an Effective Testosterone Booster?

From all my research, I could only find one significant, controlled, and published research study conducted on Spilanthes Acmella that was directly related to testosterone boosting ability. There have been multiple studies that tested its effectiveness for other medical issues, but essentially, as far as testosterone boosting characteristics, Spilanthes has been ignored by the testosterone supplement world, when it comes to scientific research and blind testing.

I am convinced that in the very near future, there will be many supplements that will include this ingredient for effectively boosting testosterone levels, along with the many other benefits as described later in this article.

Here is the information on the study I mentioned:

The study was conducted by members of the Department of Pharmaceutical Sciences in India in 2011. An extract of Spilanthes Acmella was administered to rats to determine sexual behavior after they had been given this herb. Any time sexual behavior is the intent of a study, testosterone levels are always measured before and after the study,

In this study, rats received 50 mg/kg of body weight, 100 mg/kg body weight, and 150 mg/kg body weight of the extract, for a total of 28 consecutive days.

The study found that testosterone serum levels, which are the levels of testosterone measured in your blood, did in fact increase considerably during the test.

The results of the study indicated increased testosterone levels by 20%, 68%, and 115% based on 50mg/kg, 100mg/kg, and 150mg/kg of body weight respectively after 28 days of supplementation with the Spilanthes extract.

The results of the study also indicated Follicle-Stimulating Hormone (FSH), increased 23%, 79%, and 120% at doses of 50mg/kg, 100mg/kg and 150mg/kg of body weight respectively, of the extract.

In addition, the study also showed Luteinizing Hormone (LH), increased by 5%, 13%, and 48% at doses of 50mg/kg, 100mg/kg and 150mg/kg of body weight, respectively of the extract.

So as you can see, this study clearly concluded that the traditional use of Spilanthes acmella was effective as a sexually stimulating agent, and apparently, can be quite effective as a testosterone boosting supplement.

But don’t forget, there are many other benefits of this awesome herb! Keep reading to check them out.

What are the Other Benefits of Spilanthes Acmella?

Here are the additional medicinal and dental uses for Spilanthes Acmella:


  • As a Diuretic – This helps increase urine output and early experiments on rats indicated that a cold-water extract of Spillanthes acmella acts as a diuretic.

Are There any Risks, Side Effects or Warnings With Spilanthes Acmella?

Here are some things to consider if you decide to use this natural herb:

  • The plant can cause dermatitis if you come in contact with it.
  • Should NOT be used in high doses or for long periods of time.
  • When taken it quantities beyond the recommended dosages, it irritates the mucous membrane of the intestine which can lead to gastrointestinal issues.
  • Do not use if you have acid reflux or ulcers.
  • Should not be used by women, especially if they are pregnant or breastfeeding.
  • Topical application can cause some redness and itching.

The biggest issue I have found is, you cannot take this in large quantities!!

How is This Natural Herb Normally Taken?

In traditional medicine, the plant is normally cut and then its leaves and flowers are ground. After being properly cleaned and ground, they can then be chewed to obtain the juice from the leaves and flowers. Some people like to have it in their tea as it has a pleasant taste when boiled. Many Asian areas prefer it as steamed vegetables in their meals.

In more modern times, the Spilanthes extract is being used as a supplement, where the dosage is totally dependent on factors such as weight and age.

NOTE: Make sure you check with a professional before you start taking this herb since the effects of taking it with other supplements, prescription meds, and especially alcohol have not been fully researched.

My Opinion of Spilanthes Acmella.

Turns out, this is another amazing natural herb that has many benefits in both medicine and dental application. And, it does, in fact, appear to increase testosterone levels by a considerable amount.

There are some side effects, but only if you abuse the recommended dosage, so DON’T!

Currently, I could only find one testosterone boosting supplement that includes Spilanthes Acmella. It is called Ultimate-T and is made by a very reputable company called USP Labs. The only problem I have with Ultimate-T is that the Spilanthes Acmella is in a proprietary formula so we don’t know the actual amount included. That is a red flag for me because I want to see the exact dosages to make sure we know what we are taking.

There are some really good Spilanthes products on Amazon that I recommend. Here are some of these products:

  1. I use my own herbs and plants for our medical needs where I can, but I’ve never heard of Spilanthes acmella.  Is it known by any other name?  I am very interested in it’s uses especially it’s dental uses as well as Rheumatism.  I found it also interesting to see it was used to treat Scurvy, it must have a high content of Vitamin C.  I just harvested some Rosehips this last weekend…did you know that one tiny rosehip has as much vitamin C as 10 oranges?  

    • It is know by many other names, but the main one people know it by, is the “toothache plant”. It is also called Jambu or Paracress. 

      I am aware of all the Vitamin C in rosehips and it is awesome.

  2. I may be overly cautious about these things, but with that list of possible side effects I’d say there needs to be more than one study to prove that the possible testosterone benefits outweigh the risks! If it helps with gastrointestinal problems, for instance, I’m wondering why it also has gastrointestinal problems listed as a possible side effect? Are there other herbal supplements I might feel more comfortable recommending to men I know?

    • The gastrointestinal issues will only occur if someone overuses this herb. Used properly, it will help with internal issues since it is an anti-bacterial and anti-fungal. As you know with any herb or supplement, it has to be use properly and not abused, to get the most benefits. On my site, there are many more natural herbs and supplements that are proven and will provide the benefits you are looking for.

  3. Wow! This is a really interesting article. Hopefully I will not have to use it anytime soon but maybe in the future. 

    To be honest, I prefer organic medicines than synthetic but sometimes I doubt if they are effective or not. Thank you for sharing a journal article about the plant though. 

    Do you know what would the dosage be if you are to take it raw vs if you take it as an extract? Also, do you know which form is more potent;extract or the raw?

    Last one, will it grow in a greenhouse? I live in North America where winter kills every plants 😛

    • The dosage is based on a man’s age and weight so that will vary. That is as a supplement.

      As a plant, it is used in salads sparingly for its aphrodisiac qualities, but not to boost testosterone.

      The extract is stronger and is provided as a liquid as shown in my article.

      I don’t know if you can grow it in a greenhouse, but I would think so, as long as you can emulate the growing environment in South America or Asia.

      Thanks for you comments.

  4. Hi, Curtis!

    I remember reading about Spilanthes acmella when I was writing about neuronal cell death. I did find some great resources about this herb, and I was amazed to see that it had a high therapeutic potential. But like many herbs, it does have side effects. Good thing you warned potential users to check with a professional before taking it. Sometimes people think that because a herb or product is natural, they are 100% safe.

    I look forward to reading more of your posts.

    • Absolutely, I always post the side effects and recommend you consult with your doctor before taking any supplement, especially if you have chronic issues.

      I do a ton of research as well to provide the best possible information to you all.

      Thank you for reading my articles and your great comments.

  5. I have been a farm man all my life and I always believe that nature can give the cure for many illnesses. I think we need to comeback to the natural medicine and left the drugs because the side effect are worst. Thank for this helpful post because can help many people not just in testosterone but in other areas as well. I think this herbs and nature can be useful for a lot of people. What is the recommended dose for toothache?

    • I grew up on a farm as well and I completely agree that natural herbs and minerals are the way to go if at all possible. There isn’t a dosage for toothache exactly. You just chew on some leaves until the pain is relieved.

      Thank you so much for reading my article and for your generous comments.

  6. Hi Curtis.

    I’ve not heard about this plant before now. From what you wrote in this article, it’s indeed an awesome herb. Thanks for sharing your thoughts and research about how to and if Spilanthes Acmella is a sure herb to boost one’s testosterone.

    Great contents on this website. Keep sharing.

    • Many people have not heard of it and that is why I did this review. I want people to learn about the natural alternatives to the terrible synthetic products that are out there today.

      This is a great herb with many benefits and will help with naturally boosting a males low testosterone.

      Thanks for your comments.

  7. Very interesting article.  It does seem there may be some issues if you use the actual plant.  But it surprises me that it is not recommended for women at all.  How do people use it traditionally in their foods?  I would expect that if you’re using it in cooking, the plant itself needs to be handled and would be part of a meal for the whole family.  The extracts seem to be more practical for medicinal use in any event.  Thank you for sharing.

    • Yes, it can be used sparingly in salads and is used that way for its aphrodisiac qualities for both men and women.

      It is used in dosages for men and is dependent on age and weight. Men just have to follow the recommended dosages on the label of the product.

      Thank you very much for reading my article and for your comments.

  8. You mentioned benefits of Spilanthes Acmella and I see that this herb is one of the boosters of testosterone. I would recommend a herb for dietary supplement and health booster if they have been tested through the years with no side effects.

    Since findings prove that Spilanthes Acmella is really for human being let this help men to recover and gain their testosterone for their efficiency in life.

    It is proper that you centered on this subject and your post is recommended to educate and inform us.

    • Thank you very much for your kind comments.

      Yes, this is to help men with their testosterone issues, but has many other benefits as I mentioned in the article.

      I am glad you found my article useful and educational.

  9. Liked reading your post, Curtis.  Very informative and promising but, if there has only been one study and it was on rats, how soon will a study be done on humans and when can we expect to see the results? 

    Correct me if I am wrong but humans are a lot bigger than rats so I would think that the dosage would have to be significanly higher to get the same results.  Would I be right in that assumption??

    The other uses for this herb are pretty amazing.  People were using herbel remedies in the home for thousands of years before humansthought they could do it better.  Maybe there will be a time in the not too distant future where we will return more and more to these natural remidies. 

    All the best and let us know if you come accross an update to this post. I would be interested.


    • The human study and some scientific proof is already available. And, yes of course the dosage for humans will be different and proportional as I mentioned in the article.

      I love researching natural herbs and minerals, because I learn so much more with each one. I only review natural products. I don’t trust synthetic products.

      Thank you and I am glad you found this information useful. That is always my hope.

  10. What an interesting herb! I have had a strong interest in herbs for over 30 years and always reach for nature’s medicine before running to a Dr. It seems to me this herb should be used with caution though, since it seems to be able to deaden pain on contact, similiar to Lidocaine in some ways? What dosage to you think would be therapeutic for a testosterone dose? Would chewing on it for tooth pain, release a certain amount of the T hormone?

    • No, chewing on it for tooth pain is not enough to have an effect on hormones. You are only supposed to chew on it long enough to stop the tooth pain.

      As far as dosage for men, it is dependent on age and body type and weight. They would follow the recommended dosages on the label of the supplement.

      Thank you so much for reading my article and your comments.

  11. Hi Curtis

    I kind of agree, I would also be concerned with the possible side effects. I personally would not be able to use it since I have a very delicate stomach. 

    What would the proper dosage be?  And would the dosage be the same for women and men ?

    I would want to maybe read a little more on maybe other studies that may be going on.The list of possible

    side effects it a little worrisome. I notice that most articles I geared for men, you mention on the article that 

    women also need testosterone. So if is in small amount why would it be good for women to that this supplement?

    • As I mentioned in the article, “Should not be used by women, especially if they are pregnant or breastfeeding.”.

      This is for men to increase testosterone.

      Dosages for men are dependent on their age and body style and all men should follow the recommendations on the label of the supplement.
