Does the term “low testosterone“ sound painfully familiar to you? Or maybe “low sex drive“? How about having certain “problems“ in the bedroom?

Or maybe you just haven’t been feeling it in the gym, or at work, having no drive and focus anymore. In all of the above, low testosterone can often be to blame, and the older we get the less of it we have. 

But what if we told you there is a simple way of fixing many of the hormonal problems that can stem from stress and aging?

Meet Butea Superba, a plant that has been extensively used to help treat side effects of aging in males. It offers a cheap fix to many of the most common problems such as lack of energy, erectile dysfunction, and poor sex drive.

In this Butea Superba review, we'll dig into all of these matters, so keep reading.

What Is Testosterone?

Testosterone is the primary androgen (male sex hormone). Essentially, it's a steroid produced in the Leydig cells of the testes (95% of all T) and in the adrenal glands (5%) from cholesterol.

A man’s testosterone levels peak during his twenties, and then slowly decline more and more with the years. By the age of 80, most men have about 20 to 50% of their peak testosterone. Ouch.

But why is testosterone important in the first place? Well, testosterone is the hormone that ensures male fertility, muscle synthesis, physical performance, and virility in general. Basically, everything that's traditionally associated with being a man strongly depends on having healthy testosterone levels.

To summarize, testosterone makes you a stronger man, increases your sex drive, boost physical performance, and makes you more assertive and dominant in general.

What Is Butea Superba and Why Take It?

At this point you may be wondering what exactly Butea Superba has to do with your testosterone levels, so let's get straight to the matter.

Also known as Red Kwao Krua, Butea Superba is a shrub native to Thailand. Its root has been a staple component of Thai traditional medicine for as long as any local healer can remember, helping men reclaim and increase their virility.

Long story short, it boosts testosterone.

What's amazing is that the health benefits of this plant are backed by both science and by centuries of eastern tradition. The right Butea Superba dosage provides you with a whole bunsh of health benefits that any man would like to have in his life.

Butea Superba Health Benefits for Men

First, Butea Superba increases DHT, a metabolite of testosterone which is responsible for much of its mental effects. For instance, it boosts your libido, enhances erectile function, and may give you that confident alpha male feeling. Also, there's some scientific evidence pointing out that DHT may help in promoting facial hair growth, so that's just one more reason to love this powerful hormone.

Second, Butea Superba is a cAMP phosphodiesterase inhibitor. According to some studies, this inhibition may help in enhancing testosterone production in men in the same way as it's seen with Forskolin. Traditional usage in Thailand also suggests that Butea Superba is potent in increasing free testosterone levels.


This is blood lab results that a user of Butea Superba root extract has sent us. In his case, Butea Superba has clearly increased free testosterone levels after 3 months of use.

Third, there is evidence of Butea Superba having anti-estrogenic properties. This feature basically makes it the perfect supplement for restoring male hormonal balance, since it will be inhibiting female hormones and boosting androgens at the same time.

Fourth, there are animal studies pointing out that Butea Superba can significantly increase sperm count (by up to 16%) and sperm motility, making it great natural way to help in improving and maintaining one's fertility. This effect works especially well together with the plant's ability to boost free testosterone and DHT, which are crucial hormonal factors for this matter.

Butea Superba General Health Benefits

As you may have guessed, the health benefits of Butea Superba don't end on male sexuality and hormonal health. This little beauty has so much more to it.

For example, some animal studies indicate that Bute Superba can improve cognitive and emotional function. Although the magnitude of this effect is still to be researched in humans, the tendency itself is extremely promising. Some other animal studies have reported the efficacy of Butea Superba in treating depression resulting from chronic stress.

Moving on. The main andioxidants in Butea Superba are procyanidin B2, (-)-epicatechin, and procyanidin B5. Besides protecting the cells of your body from potentially harmful free radicals (like all antioxidants do), these three substances have some unique health benefits of their own:

And, of course, there's the universal effect of all antioxidants: reducing free radical formation and cellular oxidative damage. Essentially, this is like battling the effects of aging on a molecular level.

Butea Superba Side Effects and Toxicity

Now that we piqued your interest with the astounding health benefits that Butea Superba has to offer, you may be wondering whether this plant is safe to take in the first place.

Well, there is no conclusive evidence on the existence of Butea Superba side effects, but centuries of traditional use in Thailand clearly shows the plant to be safe for daily use. However, keep in mind that the Thai equivalent of FDA have established the recommended daily dose for Butea Superba to be at about 2 mg per kg of body weight.

In terms of toxicity, Butea Superba appears to be fairly safe to take in general. However, some animal studies affirm that high doses of this plant (the human equivalent of about 48 mg per kg, more than 20 times the recommended dose) bring forth genotoxic effects, meaning that they cause mutations in the cells. That's why it's so important to stay in the safe usage zone.

So, all in all, Butea Superba is almost absolutely safe as long as you don't take absurd amounts of it.

This is a fabulous thing since the most widely adopted conventional way to improve testosterone levels today is by means of testosterone replacement therapy, which comes with a lot of side effects including impotence and hair loss. Butea Superba doesn't cause those nasty things.

Moreover, there are testimonials and research that confirm Butea Superba can reduce and slow down hair loss. This is also one of its traditional uses in Thailand. Butea Superba has also shown potent antidepressant effects in a study on mice subjected to chronic stress.

We recommend our own Butea Superba product if you want to reap the benefits of this potent Thai herbal. 


So there you have it, this is our honest Butea Superba review. 

As you see, for those men in search of some extra edge in the bedroom, gym, or life in general, this astounding plant may be just the right thing. After all, it's called Superba for a good reason, so go see it for yourself.

  1. I had not read much about Butea. It sounds promising for BPH. I have some mild issues with that and have been using red maca and pygeum which has helped a lot. I appreciate that you always have science to back up the content you articulate in your overall recommendations.

  2. Butea Superba seems awesome especially for guys like me; a 53 year old who is starting to feel the results of low testosterone in his physical and sexual life!

  3. Interesting read. What is the effects on testosterone compared to like other herbal remedies ? Like high free test in the blood ? I might just buy this stuff to test it out

    • Hi Christian,
      There are not much research studies done to support increases in free testosterone, which is why we do not market our Butea Superba product as such. However, as the labs posted in this article, testimonials and a long history of traditional use suggest that the herb’s effects sure seems to do this after 2-3 months of use.

      We do have evidence from research studies that it increases DHT and has anti-estrogenic actions, which in itself would increase free testosterone. If you take an aromatize inhibitor for example which lowers estrogen then your free testosterone will increase as well as DHT.

      Personally, I think this herb is much more suitable for use long term than others such as Tongkat Ali. I love Tongkat Ali and think it is the best natural testosterone booster out there, but the problem is it has a tendency to increase estrogen sometimes and it can be quite severe in some people (gyno, aggression, anxiety etc). Butea Superba is a better overall hormonal balancer for men with less potential to mess you up.

  4. If you’re a male this is without a doubt something you should look into! It will change your life and you’ll be glad that it did!
