Update 3/9/24. If you have not heard of Zi Xiu Tang Bee Pollen capsules (also called Zi Xiu Tang Beauty Face and Figure Capsules), this is a natural weight loss supplement where some websites actually encourage people to eat what they want! Even the educational pamphlet that accompanies Zi Xiu Tang Bee Pollen say: “No Diet Restrictions” and that people can achieve “excellent results” even while eating “high fat and high-calorie foods”. The power of Zi Xiu Tang is said to be due to bee pollen and the other ingredients in the supplement. But, things are more complicated than that. This is the second review I've written about the Zi Xiu Tang Bee Pollen. For more insights on the ingredients, see the original review of Zi Xiu Tang bee pollen. Also, read almost 1000 comments on this review and hundreds of comments on the other Zi Xiu Tang Reviews.
Read The Updates First
I posted these updates above the rest of the content so you would see them first. As you will see below, I originally felt Zi Xiu Tang was a laxative, that still did not fully explain the crazy amounts of weight people were experiencing with this product. I wondered if there might be something else behind these effects.
Unfortunately, the FDA proved my suspicions correct when they found a drug called sibutramine (also known as Meridia) in Zi Xiu Tang -as well as other bee pollen weight loss supplements. Sibutramine has been linked to heart attacks and strokes, so it was banned in the US many years ago.
Update 4/8/14. The FDA warns people to immediately stop taking Zi Xiu Tang Bee Pollen's weight loss supplements. It tested several Zi Xiu Tang products – including those that were said to be “genuine” and not counterfeit. The FDA found that some products contained not only sibutramine, an illegal weight loss drug but some also contained Phenolphthalein, a chemical that may increase the risk of cancer. See the FDA alert for more information.

Update. 10/24/12. The FDA has alerted the public that Zi Xiu Tang contains the illegal weight loss drug called sibutramine. They advise people to not take Zi Xiu tang. Click the link to see the FDA Public Notification on Zi Xiu Tang. It took the FDA 2 years to prove what I knew from the first day I reviewed Zi Xiu Tang. There was no way this stuff worked the way it did – if it only had the ingredients listed…
Update 6/26/12. I have written a review of ZXT Gold
Update 7/25/12. : ZXT Gold has been found to contain 2 drugs, see the ZXT Gold review for more information.
6/18/13 Update. Here is the review of Slim Trim U for more information.
At first, I could not explain the weight loss people were seeing with this supplement. One person who commented on my first Zi Xiu Tang review said he lost 13 pounds in 1 month!
Now I know why…
How Does Zi Xiu Tang Work?
Thanks to a friend who sent me a bottle of these so-called slimming capsules I can tell you that bee pollen is NOT the active ingredient in Zi Xiu Tang.
If Zi Xiu Tang works, it's because it's a laxative!
I know this is true because several of the ingredients in Zi Xiu Tang have laxative effects. I suspected this because many websites selling Zi Xiu Tang use the word “cleanse.” Cleanse is the alternative medicine term for laxatives.
Probably, the most famous ingredient in Zi Xiu Tang is senna. Senna is not a weight loss supplement; it is a laxative. The FDA also classified it as a non-prescription, over-the-counter laxative drug.
Several other ingredients as you will see also act as laxatives.
The problem with laxatives is the only weight they help us expel feces (poop) and water.
What Does Zi Xiu Tang Mean?
The supplement's name doesn't seem to refer to anything specific. When translated from traditional Chinese to English, the name means “self-show soup.” However, when translated from Literary Chinese, the word means “be.” Could this be a reference to bee pollen, the alleged key ingredient?
Zi Xiu Tang Ingredients Label

Even if you wear eyeglasses, you will find it very difficult to read the ingredients in Zi Xiu Tang. The bottle and box abound with decorative Chinese art and characters, making reading the ingredients very difficult.
The red lettering of the ingredients makes it doubly hard to read. I had trouble even when I held the bottle up to a lamp! So, to save you the trouble, I've listed the ingredients here.
Zi Xiu Tang Full Ingredients List
Here is the entire list of ingredients in Zi Xiu Tang.
- Bee Pollen
- Chinese Yam
- Barbary Wolfberry Fruit
- Lotus Seed
- Dietary Fiber
- Green tea
- Rhubarb
- Aloe
- Cassia
- Astrigillis
- Polygonum multiflorum
- Lotus leaf
- Gynostemme
- Radish seed
- Malt
- Mulberry
- Hawthorn,
- “Vitamins”
Tthe first 4 ingredients are not weight loss herbs. I've already covered these ingredients in my first Zi Xiu Tang review. Let’s now talk about all the other ingredients.
Zi Xiu Tang Ingredients and Side Effects
Senna. Senna is a laxative. Because Zi Xiu Tang contains senna, it’s possible that the same side effects from using too much senna may be seen in those who take Zi Xiu Tang. The side effects can include,
- Diarrhea
- Abdominal cramping gas/bloating
- Flatulence
- Dizziness
Because of diarrhea, products like Zi Xiu Tang that contain senna may in extreme cases cause excessive loss of electrolytes. This can lead to muscle weakness and maybe heart problems. This is because electrolytes are needed for muscle contraction and the heart is a muscle.
People using heart/blood pressure medications should not use senna-containing supplements or products that have similar laxative effects.

To highlight what can happen with senna overdose, there is a case report of a woman who developed liver failure after long-term use of senna tea.
In this report, the woman was drinking a liter of senna tea that contained 70 grams (2.5 oz) of senna fruit. Even with this amount, it took 3 years before liver failure presented itself. This is worth mentioning because everybody is different, and people often think “more is better,” which isn’t always true.
Unlike the laxative effect of fiber, senna is a non-fiber laxative. It works differently to relieve constipation. One of the ingredients in Senna is a class of compounds called anthranoids, which exert laxative effects by damaging the cells of the colon. Because of this, some have speculated that long-term use of senna, may increase the risk of cancer
Because senna supplements have not been studied for long-term use, it is hard to say if this is true or not.
Senna products should be avoided in people who have
- Hemorrhoids
- Heart disease / Blood pressure issues
- Abdominal pain
- Bowel obstructions
- Pregnant or nursing mothers (for obvious reasons)
- Diabetics
In theory, long-term use of senna supplements may make it harder to defecate as the person becomes dependent on the product.
People who take Zi Xiu Tang may notice that the color of their urine looks pink or rust-colored. This is probably due to the senna (and polygonum multiflorum, discussed below) and is not dangerous.
Update: In 2010 Senna was apparently removed from Zi Xiu Tang. Some people report that their bowel movements are less while others report no change. See the comments for more information.
Cassia. Zi Xiu Tang also contains Cassia. While the word cassia is sometimes used to describe the spice, cinnamon, I don’t think this is how they are using the word because cassia can also be another name for senna.
Both of cassia and senna are listed separately on the Zi Xiu Tang label; cassia appears first, followed by senna. Both words are sometimes used together (“cassia senna”). Other names for cassia senna are Cassia acutifola, and Cassia angustifolia.
If cassia on the Zi Xiu Tang label refers to cassia senna, then this, too, is a laxative and likely works synergistically with senna to promote a greater laxative effect.
Green Tea. Zi Xiu Tang also contains green tea. Because green tea contains caffeine, it’s theoretically possible that the caffeine may slightly raise metabolism. This is likely why the Zi Xiu Tang says “increase metabolism” and “increase energy” on the front of the display box. The box does not say how much caffeine is in Zi Xiu Tang.
Rhubarb. Zi Xiu Tang contains Rhubarb which also has laxative effects. It may also have estrogen-like effects. Rhubarb may act synergistically with senna and cassia to cause a greater laxative effect.
Aloe. Zi Xiu Tang contains aloe as well. Aloe juice also has a laxative effect however the bottle does not say if Zi Xiu Tang contains aloe juice or not.
Astragalus. Like all herbs, there are many types of Astragalus. Often used to treat the common cold, this herb does not seem to have any laxative effect. As for astragalus side effects, in large amounts (about 1 ounce, which is likely more than is in Zi Xiu Tang) this herb may increase the immune system which, while good for some can also be bad for others like those with some immune system disorders such as rheumatoid arthritis.
Polygonum multiflorum. This is an herb also known as Fo-Ti and Ho Shu Wu. Some research notes Polygonum multiflorum has a mild laxative effect. At least 7 case reports have noted liver problems including hepatitis resulting from use/misuse of this herb.
Other reports hint that Polygonum multiflorum might alter blood sugar levels (that may be bad for diabetics).
On a side note, Polygonum multiflorum may also be found in supplements designed to lower cholesterol; research suggests that extracts may lower cholesterol and increase HDL. More research is needed to confirm this.

Gynostemma. Some websites say this herb can both cause both weight loss and weight gain. In this respect, Gynostemma might be classified as an adaptogen. An adaptogen is a non-medical term used in some circles to describe how a supplement “adapts” to your needs. Websites also claim that gynostemma has laxative effects.
Radish Seed. I could not locate any weight loss effects of this ingredient.
Malt: I could not locate any weight loss effects of this ingredient.
Mulberry. This contains fiber which acts as a laxative.
Hawthorn. People who take medications for high blood pressure or a heart condition should not use hawthorn or supplements containing Hawthorn. Hawthorn does influence the way the heart pumps. This means hawthorn can interact with your heart or blood pressure medications.
Vitamins. Zi Xiu Tang lists “vitamins” but does not indicate which vitamins it contains.
Ingredients that are Laxatives
To recap, here are the ingredients in Zi Xiu Tang that are laxatives
- Senna
- Cassia
- Rhubarb
- Aloe (if it contains Aloe juice)
- Polygonum multiflorum
- Gynostemma
- Mulberry

Who makes Zi Xiu Tang?
The company that makes zi xiu tang is said to be the Guangzhou Zixiutang Biotechnology located in China. The strange thing is that I've never been able to find a picture of what this company looks like. Google searches turn up no pictures of the company. Even the website for the company – cn-zixiutang.com – does not show a picture of the company (the website no longer exists).
For more info on the company, see my review of the bee pollen weight loss supplement Slim Trim U.
Zi Xiu Tang Warning Label
If you read the label of Zi Xiu Tang you see this warning of who should not use the product (I'm quoting them verbatim):
“Not Suitable For:
Women who are pregnant or breastfeeding. People who suffer from either liver, kidney, Heart Disease, or High Blood Pressure. Adolescents, Elderly, Depressed people, or Anyone with bee or pollen allergies.”
Does Zi Xiu Tang Work?
There is little clinical evidence of weight loss effects for most of the ingredients in Zi Xiu Tang. If it really works, it may be due to laxative effects. Some websites that sell Zi Xiu Tang say the product does not contain sibutramine (weight loss drug), or other drugs like Rimonabant (weight loss drug), Phenytoin (anti-seizure drug) or Phenolphthalein (has laxative effects). This is perhaps a response to previous FDA action against bee pollen-containing weight loss supplements. Does it work as well without pharmaceutical enhancement? You tell me.
I’ve been taking the pills almost a month now & have lost 12pnds! Yeaaaaaa but I have decided 2 stop taken the pills because they are messing with my vision! My eyes are itchy and watery, almost like allergies but I’m not allergic 2 anything, never have been! So my only conclusion is the pills are messing with my eyes! Is anyone experiencing this side effect in addition 2 the extreme thirst, occasional headaches and decreased appetite?
Nancy, what you say may be correct; since you weigh less it may be harder for you to lose weight. Did you buy your zxt from the same place your friends got it from?
I bought these pills from the actual website. Have been on them for over 2 weeks now and I’ve only lost 2 lbs 🙁 this annoys me because my friends mother has lost 12 in JUST 2 weeks. Is it because I am (was) only 135 so I have less fat (guess you could say that) than someone who’s 50? I do feel less hungry, I barely eat but still not a big lose. I don’t eat horrible at all either. Its so upsetting. Any ideas? help? What could it be?
Sherry good luck and no stress – I’m sure you will be fine 🙂
Joe- I took 2 pills yesterday and I am going to take my drug test now. So wish me luck! I also want to mention that I do not do drugs and I am not taking any prescription drugs. So I should find out in a few days the results.
FDA update Chinese weight loss supplement laced with weight loss drug
http://www.fda.gov/ICECI/CriminalInvestigations/ucm241467.htm
Its not zxt but stuff like this makes me suspicious
B, I appreciate your passion (and I hear your anger toward me). You would not want me to lie to you about Zi Xiu Tang effects and side effects would you? I usually don’t give my opinions without any facts to back them up.
I try to base everything I say in either scientific proof or rational thought (does it make sense). I have occasionally posted my opinions on Zi Xiu Tang in the comments of my reviews.
Because off the lack of research I can’t say that zxt will alter a drug test, interfere with prescription medications or anything else people wonder about because I have nothing to base my conclusions on.
I believe I have written the most unbiased reviews of Zi Xiu Tang on the web today. But there is a lot that we don’t know because of a lack of research.
B, you say zxt doesn’t just act as a laxative. Then tell me what ingredient or ingredients are causing the effects you and others have experienced. What ingredient in zxt suppresses your appetite? I’ll investigate those ingredients for you.
Does anyone notice how Joe says he “isn’t aware” of ZXT helping anything? You aren’t educated and you have no idea! It is absolutely not just a laxative, I have been taking for about 4 months and after the detox was over my bowel movements are completely normal. It suppress your appetite and speeds up your metabolism. I stopped for a month and didn’t gain ONE pound back that I lost. I’m on it again to lose my last 10-15lbs. Joe, you know nothing. You are a joke.
Sherry, that’s a good question. I’m not sure if xi xiu tang effects drug tests. In theory it shouldn’t. When was the last time you took zxt?
When you get the drug test results, would you let me know. I’m very curious.
Hi, I have been taking these pills on and off for 4 months. I have to take a drug test for a new employer. Will these pills cause my drug test to come up positive? I have heard that happen for other diet pills.
Susan. I’m glad you are feeling!
Just wanted to let you know that I did speak with my doctor and she said to stop taking the pills. She did blood work and everything came back normal since I have stopped taking the zxt. She has temporarily put me on blood pressure medicine to help everything settle down.
It only took 3 days after stopping the pills that I started feeling a lot better. I am able to sleep at night again no more headaches or other problems. My doctor said it could have been an allergic reaction to one of the ingredients we just don’t know which one. Everyone is different that is for sure.
Joe, that’s a great question. wish I knew the answer. I do know however that it is possible that the old zxt with the senna, may have been sold to another company. Otherwise, why would they change a product that was working? This marketing stuff is all new to me so I dont understand it all. I know the product somewhat works for me as long as I am doing my part with diet and exercise. This is definitely a no exercise pill. I prefer zxt over the phentermine that was prescribed by my doctor, however, if we do find out there are unsafe ingredients in zxt more hazardous than the meds I currently take, then I will stop taking it,
Tami, how do we know there is not more than one company in China that makes zi xiu tang? its a big country. How do we know this is the main, real deal, zxt company?
The only way to verify authentic product is via the anti counterfeit code located on the label on the back of the bottle. This label should have a website 61131115.com printed on it and a 20 digit code under the carbon scratch off area. Both the label/code and the site are controlled by the manufacturer in China and will provide you with the information needed to verify the authenticity of the product. Also real capsules come in a bottle/box written in English whereas the fakes are in Chinese and the real capsules are 60 count NOT 48
Hi Nicole,
When I investigate supplements I have recently started seeing what I call “dummy websites”. Basically they are sites that are related with the supplement but they contain phrases like “zi xiu tang scam” or “zi xiu tang rip off” because they know we search the web for these words when we want info. So they create websites containing these words to drive traffic there.
The main reason of these sites however is not to educate people but to sell the product.
Sometimes these websites may be trying to sell other products by piggybacking their marketing on other more popular supplements.
Just wanted to mention this to you.
Hello everyone,
So I’m excited to give this a try, after doing some research on my own and hearing the reviews posted here. My only question/concern is the stuff I have read about the Zi Xiu “scam” or the people warning to make sure you get the real stuff, that there are a few websites that sell a version of it that isn’t legit. Can anyone tell me where they ordered their bottle? Was it amazon? Or is there some official website I can go to?
Any feedback would be greatly appreciated.
Thanks!
Wishing you all the very best 🙂
S, thanks for stopping by and keep me posted on your progress. Having lots of muscle is important. its good you know that 🙂
Hi Andrea,
If I had to guess I’d say it may be the caffeine that is responsible for appetite suppression with zxt. I am admittedly guessing on this. As far as I can tell, none of the ingredients in zxt have specific appetite suppression. Caffeine, by nature of making people more awake, might – in theory- make people forget to eat because they are being more active.
I am shooting from the hip on this Andrea, because other than that I just dont yet have an explanation. I will keep you posted as I learn more. I am still trying to find somebody to test zxt in a lab.
Hi,
Yes, the symptoms have subsided and the weight loss has slowed/stopped. Once in a blue moon I will have dry mouth or lower appetite but I figured the holidays destroyed the lowered desire for sugar!:(
I took a break after taking it for 4 months and had a 22 lb. loss. I went back on and my weight is not budging and minimal side effects. I believe I got out of hand after not during the holidays and it is catching up to me.
My plan is to continue. I workout 8-10 hours a week pretty hard core and carry a lot of muscle mass so as long as I can keep going at 45 years old and work full time and maintain if not lose the weight, I’m happy!!!!
I have posted in the past and have had most all of the side effects but enjoyed the weight loss. If the weight loss ends then I will quit the supplement.
Thanks!!!!
