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.
Thanks for the info Joe. Isn’t it funny how all of these diet pills from China are “natural”? Sure, they’ll say anything to convince consumers to buy it! Americans are easy targets for weight loss schemes, and these manufactures don’t care if some die or are harmed while taking these products, as long as they make a buck. I know this may sound harsh, but it’s true folks.
Only they know what’s added in these supplements that they’ve not disclosed to the public, and as sure as my name is Catherine they’ve added something to zxt that has not been disclosed to the public. Thanks for posting this info again Joe 🙂
Did everybody hear about the FDA recall of the Chinese weight loss supplement Fruta Planta? it contained a weight loss drug that is now banned in the US. According to the FDA one person died from heart failure.
There is no relationship to zi xiu tang but since both come from China I thought this was relevant. Here are links

Darlene, wow that’s a terrible side effect. Darlene, can I recommend you go to your doctor about this. Passing blood in the stool can be due to many different things. I would sleep better if I knew you were checked out by your doctor. Let us know what she/he says.
I started taking the pills about 3 weeks ago, but stopped a few days ago. I’ve been bouncing around the same 5-6 lbs weight loss, but the most difficult side effect is severely bleeding hemorrhoids, and abdominal pain/bloating… It seem that I was passing as much blood as stool. Since stopping the pills, my movements hasn’t returned to normal yet, and I’m really bloated… The 5-6 weight loss wasn’t worth it. I think I’ll just hit the gym, and walking.
My experiences with these pills wasn’t bad, but wasn’t fantastic either. I didn’t have any bad side effects, just headaches if I didn’t eat enough. I lost a lot of my appetite, but again, if I didn’t eat often enough, I’d feel sick. Lots of insomnia, but I took the pills around noon. I could stay awake till 3 a.m. without any problems (and as a college student, that was ideal).
I’ve been on the pills about 2 weeks now and have lost 5.2 lbs without exercise or purposeful change in diet. The effects of the pills seem to slow down as I’m on them for a longer time.
All in all, I will finish this bottle, but probably won’t order them again. I don’t mind that the weight loss is slow, but I feel as though I’m losing mostly water weight. My clothes don’t fit any differently.
Also, for reference, I started at 103 lbs. Because I weigh so little to begin with, that could have caused the weight loss to be slower.
I wish I had found this site a month ago. I began using this product on November 17th, 2010 and as of today 12/25/10, I have lost 22 lbs. Although my weight loss is exciting, I stopped taking the product when I finished the bottle. I told myself that I would not buy another bottle. I’m so glad I made that decision because now that I found this site, I can back up my decision to anyone who asks me why I quit taking the pills. I have experienced side effects such as EXTREME dry mouth, even when drinking the recommended amount of water, the inability to defecate as effectively on my own (it was really hard for me to contact the muscles), and a rash of small flesh colored non itchy bumps all across my shoulders, arms and chest. The dry mouth and defecation problem are the main reasons I have decided to discontinue the product. WARNING TO EVERYONE WHO IS TAKING OR WHO ARE THINKING ABOUT TAKING THIS PRODUCT….PLEASE DON’T!!!!!!! You will be putting your health at serious risk! Although these pills did curb my appetite and made me lose weight if I knew then what I know now, I would have stayed away from these pills. For years I stayed away from the other weight loss pills that contained known harmful chemicals such as Ephedra, because I was scared of the side effects, but I never thought that something that contained “natural” herbs and ingredients could be just as harmful. My eyes have been opened and I guess its back to the gym I go for some good old fashioned workout weight loss. Thank you for publishing this life saving article, I will definitely be sharing this article!!!!!!!
I saw this on the FDA website and thought I would pass it along: Basically the person was caught importing diet pills from china that contains prescription medications.
http://www.fda.gov/ICECI/CriminalInvestigations/ucm237407.htm
zxt isn’t mentioned specifically. Just thought I’d pass it along in case the company looked familiar to anyone.
my starting weight was 190lbs
Kayla you lost 15 lbs in 1.5 weeks? Honestly, that just doesn’t sound healthy. If you dont mind, can you say what your starting weight was when you first took zi xiu tang?
Ive been taking zi xiu tang for a week and a half, so far I’ve lost 15 pounds. I haven’t really had any side effects at all except I have to remember to eat because I just never get hungry now, my friends have commented on how much smaller I look. So i think its pretty awesome, lol
The first time I took it I lost 11 pounds, but once I stopped I gained it all back. 2 bad side effects for me diarrhea and excess phlegm in my throat. I have a constant urge to hack up crap! It’s gross
I thought I would try it again, but I can’t stand the 2 side effects. Plus, I am on high blood pressure meds and after reading about the effects, I’m stopping immediately
Some people have asked if I would write a review of Hawthorn since it’s in zxt. I just posted it. Here is the link: http://supplementclarity.com/hawthorn-review/
I hope it helps 🙂
I started ZXT on Tuesday, and I have not had any bad side effects…the first day or two it made my stomach hurt, but then i was fine. No loose motions or excessive dry mouth. I’ve lost 2 lbs in 4 days by taking 2 pills a day. No appetite suppression, I’ve been eating the same.
Hi,
Has any one had any side effects from ZXT that has developed diabetes or diabetic symptoms?
Not myself but someone I know rapidly developed diabetes right after taking ZXT and feels that it caused or contributed to high sugar.
I don’t think so but……..wanted to know if anyone has had this happen.
Well went back to the DR and the blood pressure is perfect my heart rate is a little high but i had just had a flu shot before they took it sooo? I’m down another 7 pounds so that’s almost 80 now. Thank you so much for all the info Joe! I honestly think i would have been blinded by my success to think any of my side effects were from the ZXT. Whether it really works or its something like the placebo effect at least for me I can ignore the result..
Inertia have a fun time in Indonesia 🙂
Well it’s been exactly 8 weeks on this and I’ve lost a total of 13lbs.
The appetite suppressant part of it doesn’t feel as ‘obvious’ as it did in the beginning, but it’s still there. What I mean by that is when you do go to eat, you still feel full a lot sooner. Nor are there any cravings still.
Thanks Nikki for your words of wisdom, I appreciate it. Haven’t been very good with measuring but I know the body is shrinking because I’m down a pant size as well.
Well happy holidays to you all. I hope you get thru the next few weeks without wreaking havoc on your body. I’m heading to Indonesia in a few days so I won’t be on here until the new year.
This pill definitely suppresses my appetite and increases my thirst dramatically. The appetite suppression may be due to frequent trips to the bathroom for lose stools from the laxative, that ruins an appetite!
Nikki, when I reviewed zxt I didn’t see any evidence for any of its ingredients being an appetite suppressant. Other than having a laxative effect, I can’t find a mechanism how it would work. Hence my suspicion about it having “other ingredients”.
Joe..im only assuming thats part of the way it works..that and keeping you from being hungry..but you know what they say about someone who assumes..haha.
Do you know which ingredient in the ZXT actually is the appetite suppressant? I would much rather just take whatever that is the keep on taking this pill if all the ingredients are not listed on the bottle.
