China Brush, also known by the tongue-twister name of Suifan’s Kwang Tze Solution, is an unusual desensitizing product to help men delay ejaculation.
The main appeal is that it contains natural ingredients, instead of the usual pharmaceutical anesthetics like Lidocaine or Benzocaine.
The good news is that it helped me last much longer during sex. The bad news is that despite the pleasing improvement in time, I discovered 2 major problems with it which I’ll be discussing later in this China Brush review.
What I was also very interested in was the ingredients; there’s always something that feels mysterious about Chinese medicine and herbs – to me at least.
So I wanted to know exactly how and why China Brush works. To find out I did some research into each of the 8 main ingredients to find out exactly what I was putting on my most delicate parts.
I’ll share these findings briefly below and then discuss in more detail what I found good and bad about China Brush. If you’re not interested in my obsessive compulsive dissection of the ingredients, scroll down a bit to find out more about how it works.
China Brush Ingredients
Please note that I didn’t waltz into a Chinese herbal remedy shop with a beaming smile and ask for a breakdown of these ingredients. This is simply a summary of some basic online research.
1. Fructus Cindii
This is a dried fruit of the Cnidium plant. It’s used in Chinese medicine to help guys with impotence. It has nothing to do with holding back ejaculation, but does seem like it could add some strength to your erection.
2. Cortex Cinnamomi – Cinnamon bark
Cortex Cinnamomi is listed on the World Health Organisation website, described as being used according to ‘folklore’ to treat impotence. But they also add the caveat that there’s no clinical data to support this or any other purported benefit.
According to Chinese medicine websites it’s a potent aid for those who have a low sex drive; it helps build strong internal and physical sexual energy. So again, nothing about delaying ejaculation, and more about being a natural Viagra.
3. Flos Caryophylli – also known as Ding Xiang and Clove
Flos caryophylli is the dried flower of the Clove tree. In one experiment involving rats it was found to significantly increase sexual libido. It’s also apparently used to numb tooth pain by rubbing it in. Perhaps the creators of China Brush have decided that it would also numb other body parts.
4. Rhizoma Alpiniae – a kind of ginger
This root is very similar to the type of ginger used in cooking. I couldn’t find anything to suggest a use for it in China Brush. Its medicinal properties seem mainly around stomach problems.
It does have an anti-inflammatory use, so maybe with all the action the first 3 plants might lead to, that would be useful!
5. Rhizoma Atractylodis – also known as Cāng zhú
Cāng zhú is a dried Rhizome which again doesn’t appear to have any obvious connection to premature ejaculation. It’s widely used in Chinese medicine, but not apparently for any sexual reasons.
It’s used to improve fatigue and night vision though. So perhaps again the creators of Kwang Tze Solution were being, well, creative.
6. Pericarpium Zanthoxyli – known as Prickyl ash Peel or Chinese Pepper
Chinese Pepper is the first China Brush ingredient which does have an anesthetic property. Native North American Indians used it is a numbing agent for toothache. So perhaps it could also help to reduce the sensitivity of the penis, and thus delay ejaculation.
7. Radix Angelicae Dahuricae – also known as Bai Zhi or Angelica
This root is also definitely known in Chinese medicine as being a pain reliever, among other uses. So there are at least two, and possibly three, China Brush ingredients which are known pain relievers. And pain relievers, if they work by applying directly to the skin, could help numb the penis during sex.
8. Radix Ginseng – Ren Shen
Radix Ginseng is the dried root of the Panax Ginseng herb. It’s widely used in Chinese medicine to promote good Qi – the internal energy. One study of 90 men, quoted by the World Health Organization, states that it helped with impotence problems and libido.
The organization also states that it’s been found in studies to improve physical energy levels. So it does appear that including Radix Ginseng in China Brush could make sense.
9. Other ingredients
Water is also used in China Brush solution to create the liquid it comes in. I’ve also read reports that it can contain Aloe and Gallstone. But I don’t know where this information is being found. As far as I know, I’ve listed all the ingredients that are included in the official Kwang Tze Solution.
Hitting the problem from different angles
On the surface these 9 ingredients appear to stand up to scrutiny: there are ingredients which work as anesthetics, and so should reduce sensitivity; others which boost libido; and a few which help with erection strength. There are even energy boosters and an aphrodisiac thrown in for good measure.
It appears to me then that China Brush was designed to work from several different angles. And it seems that they’ve found a way to combine all 9 herbs and roots to good effect. Or have they?
Problems and side effects
China Brush definitely has the potential to help some guys delay ejaculation. Especially if your problem is caused mainly by physical sensitivity like myself. 10 minutes extra? You can’t deny that that’s a huge improvement.
But there are a couple of issues which bothered me about it:
- You have to apply it anything from 30-60 minutes before having sex. That means you have to plan sex in advance every time.
- If you apply too much it can sting or produce a rash. I didn’t get a rash, but did feel a mild burning. And even though it went after a while, it was still unpleasant. Did I put too much on? Possibly, but I don’t think I used a lot. And at the end of the day I don’t want anything that does that anywhere near my penis.
Fake or authentic, and where to buy?
It seems that Suifan’s Kwang Tze Solution is as difficult to find as it is to pronounce, as many online sex shops have discontinued it.
There are also many reports of fake China Brush bring sold. And there are various different theories as to which color label, type of application stick, packaging, bottle etc are genuine, and which are fake.
Some readers have left comments describing the difference between the authentic and fake, but often referring to a 2009 eBay description. However, that was 8 years ago and it makes sense that the manufacturer has changed their label and packaging since then.
A new Chinese herbal retailer
After a couple of readers said they got it from Rootandspring.com, I wrote to ask about the version they are selling, and if it’s authentic.
I got a reply from Cindy, who agreed for me to publish her reply:
We obtain our inventory of Suifan’s Kwang Tze Solution directly from their sole distributor in the U.S. Our distributor is the only confirmed distributor in the U.S. and has a longstanding record with Suifan’s Medicine: they have provided to reputable companies over ten years before and after the rebrand of the product, and we’ve seen verification of the exclusive relationship they have with the manufacturer. For these reasons we have no reason to doubt its authenticity.
There seems to be a discrepancy of information on the web. I do think its worthwhile to clear it up. Yes, they’ve tweaked the formula a few years ago, it is now lighter in color and they’ve had a packaging rebrand, but it all still has the same ingredients and comes from the same manufacturer (Suifan’s Medicine) in Hong Kong. It may be worthwhile for you to review the current Suifan’s Kwang Tze formula on your website since the old one has been discontinued and no longer in existence, to see if you agree with the assessment above. I think sometimes, because the look and formula has changed over the last few years, a few customers assume it is fake. This is not the case, the product is not fake, just updated, and I have confirmed this directly.
Since then, I’ve bought their version, and also one from lovehoney.co.uk to see how they compare. In the photo below you can see both versions. The yellow label is from rootandspring, and the blue from lovehoney.
Love honey also have a US and European online store. At the time of writing this, they don’t seem to stock it any longer. But it’s perhaps worth checking if you can’t get it from the two sites above.
