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.
Tenneh, Ill take a look at Bethel30 and see what I can turn up on it. Thanks for letting me know about it.
Joe- Sorry its actually called bethel30. It’s another weightless pill. It was created by a Doctor in New York and is manufactured here in NY. It also to comes with senna which is optional for you to take with the pill. I wanted to know if you have heard anything about it. Its pretty popular from what I’m reading and many people have loss a lot of weight from it. I haven’t really heard of any bad size effects from it yet unlike the zi xiu pills. I was considering taking it but wanted another opinion. Thanks:)
My friend and I used the product for a month.
Although I see the listed ingredients, there must to be some prescription strength substance present. ZXT suppresses the appetite so much that one could forget to eat. Initially zxt acted like a laxative, but later made me nauseous and constipated with extreme dry mouth. My friend and I no longer take the zxt. My friend has to see a doctor, because she is experiencing difficulty with bowel movements. I would not recommend zi xiu tang.
I have been taking these off and on for a few months and they definitely don’t curb my appetite the way they did at the beginning. I am only taking them for another 2 months until I go on vacation I was wondering if anyone had ever increased to 3 or 4 pills per day when they have hit a plateau?
Andrea. based on that I would not take zxt several hours before bed time just to be safe
Tenneh, I have not heard of Bethal30 what is it and whats it supposed to do?
Funny I wrote that comment last night before going to bed. I mentioned that I’d only been taking this for a few days and each day I seem to have more energy and be more thirsty. Last night I went to bed around 1am and woke up at 5am feeling extremely thirsty and totally awake! I never, ever wake up in the middle of the night. I was able to force myself back to sleep, took about half an hour, but I am hoping this passes! I did not mention that in my previous post that I know at least 10 people who have been taking this supplement, some since last spring, and who have ALL lost weight. My friend’s boyfriend has lost 87lbs and is now back at the weight he was in high school. He does not exercise at all. I am going to take the pills for one full week before weighing myself. We will see…
Joe- Have you heard of Bethal30? Would you recommend that? Thanks!
Andrea thanks for letting me know about your side effects.
I just started taking ZXT last week and I’m not sure if I’ve lost any weight (don’t have much to lose) but I definitely feel most of the side effects mentioned. I have a lot more energy, don’t sleep as long at night, and my thirst has increased as my hunger has decreased. My bottle does not list senna as an ingredient. I have noticed a slightly increased heart rate while doing my usual 3 mile run on the treadmill. I’m going to continue with this bottle, and I’ll keep you all posted!
If you really want the energy Bee Pollen can offer, go to a natural store, one that has home grown honey and ask them if they have raw bee pollen. It’s hard to swallow because once dried out they are hard little granules but it does work for energy. They say bee pollen has all 22 essential vitamins and minerals that the bodies needs.
I believe I have had serious side effects using this pill. The first time I took as directed – two pills in the morning. I felt like I was on speed. The energy running thru my body or when I touched my head was very much like when I used to do speed.
The hair on my arms would rise up for no reason. I started to feel my heart flutter in my chest so I cut down the dosage (i am sensitive to caffeine) but then I was to wired to sleep. I got scared and threw the pills out. Things calmed down and I really wanted the promise of weight loss so I tried them again. After a week or so I was very agitated.
My heart was palpitating again and I couldn’t sleep. Eventually my BP just shot up (126/133) and my pulse was racing between 130-140 bpm and this was 4 days after I stopped taking the pills again because I didn’t feel right.
Ending up having to undergo a whole cardiac process. So far everything has come back as normal. This happened the week after Christmas. It should be noted that since 2004 I’ve had palpitations and bouts of tachycardia on and off but never have I had BP problems. Needless to say, no more pills for me.
Jill
the others who have taken zxt do say that the new formula does not have senna. I honestly dont see how it works if it doesn’t have senna however. none of the ingredients have any weight loss effects. I am going by the research studies on the ingredients.
I know a lot of people online have good things to say about zxt but since I don’t know who they are or their motives its hard to comment.
Have you tried eating from smaller plates, bowels and taller glasses. I once met someone who lost 50 pounds by doing just that.
Joe-
Do you think that there are any other brands that are healthier? Meaning, without the Senna? It concerns me about taking something that is noted as a laxative. All other reports that I read about Bee Pollen seem to be positive…what do you think?
Hi Jill
I just dont think bee pollen is doing anything -good or bad- for you. Everything I have read on zxt tells me that bee pollen is just hype.
Ok, so I have read all these comments and not sure what to do. I started taking these pills and have had the same symptoms that Jezzica had: Chills and not sleeping at night, heart palpatations, laxative effects and, the positive side of it, an extreme amount of energy. I am getting so concerned because the majority of these can’t be good in the long run. However, I do like the increased amount of energy, perhaps there is another Bee Pollen product out there that is better for us? Anyone…???
Jezzica. I’m not aware of any evidence that zi xiu tang helps
endometriosis. When I reviewed the product I did not see any clinical studies on this. If you have evidence please do post it I’d like to see it
As for zxt “flushing the fat out of your system”, there are no listed ingredients in zxt that do this. At best zxt is a laxative but I don’t think that wouldn’t necessarily mean it causes only fat to flush. There would be fat, carbs and lots of water flushed from the body.
Just because zi xiu tang is herbal doesn’t mean we can’t control what goes into it. It can be regulated so that each pill contains the same ingredients. herbal doesn’t necessarily mean we cant know whats in it or that different people will react differently to something. just my 2 cents 😉
I have been taking this for a week now. I am 25 years old and have no intention on losing a great amount of weight but I have read other great things about this. I have endometriosis to the extreme and have read where this has been shown to help with it, so that is my main reason.
My friend has been on this for 2 months (everyone I know is taking 2 pills a day) and she has lost 41 pounds! My neighbors have been on it for 12 days, one lost 12 pounds, one lost 16!!
I’ve definitely noticed my energy level has risen, I dont sleep very much, about 4 hours a night (verses my normal 8-9) I also notices the chills, I do get chills toward the evenings, an sweat at the same time! I haven’t had the extreme urge to go to the bathroom like most I have heard BUT I am a vegetarian and I eat extremely healthy so I dont have a lot of fat intake, in which is the reason this pill makes you want to “go” is to flush out the fat in your system.
Overall I’m pretty excited to see if it helps with my endometriosis , also the ingredients are supposed to help with infertility (Which is a plus seeing how my husband and I have been trying for over a year)
Every single pill is going to react different with every single person, its all herbal, I feel confident in this and wish everyone well and good luck 🙂
I took this product for 4 months and had only limited success. I had very large bowel movements for awhile then had less bowel movements than normal. I did loose 12 pounds. 10 of that during the 1st 6 weeks. On the product at first I had heart palpitations and extreme thirst. The palpation’s went away but the thirst did not. I decided after research to go off the product since I take BP meds. Some weight has come back on (3 #’s) but I have been eating larger meals. I’m hoping to see that I can go back to the very small healthy meals and see some result. Thank you for your research.
I have been so tempted to take this pills…I just wanted to try one bottle and see my results…but with all the side effects I have been reading about I’m not so sure anymore 🙁 .
