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.

Tamera thanks for letting us know. I don’t know what in zi xiu tang is making you feel “high”. While I dont think you will
“croke”, the high feeling is strange. if things get stranger do stop taking zi xiu tang and see your doctor.
Inertia thanks much for your kind words. Much appreciated. I am as interested in this product as everybody else is so I enjoy reading all the comments 🙂
I’m on day 2 of zi xiu tang. I have a very low appetite ( which ish weird because I’m starving every 40 minutes ) I ate twice yeasterday and I have not been too thirsty but I do feel medicated. I feel kinda ” high ” I hope I don’t croak from this stuff but the reason I started taking this is because I have been battling with weight issues for quite a while and my bfs cousin who was 285 lbs lost about 160 lbs in 5 months and she looks amazing! I wanna look amazing too. I’ll keep u updated on how I feel. And also, I have had no diarrea.
Oh by the way, I’ve requested from one of the distributors any clinical trials results they might have, particularly with long-term use. I’ll pass it on to you if they provide one.
Day 21 update:
Weight loss: 6.2lb
Notes:
Appetite & ‘craving’ suppressant effect sustained as well as mild energy boost
Still no laxative effect what-so-ever
Mild thirst most days but not extreme as ‘cotton mouth’ etc.
No other side effects occurred (ie the ‘heart burn’ or mild head aches I had in the beginning).
Most days (5 out of 7) I’m only taking the 2 pills a day.
Not to get too personal here but I think the women on here might appreciate this (so close your eyes for this next part Joe), but this week would have been the time of the month that would have seen without fail at least a 3lb (sometimes up to 5lb) weight gain. This time round, those days I either maintained or lost. Some of the other symptoms that have been a constant for that week (swelling pain, bloating, etc.) were inexplicably absent as well.
Again, I know my weight loss is not as impressive as others have experienced on here but for someone who has been fighting ‘metabolic syndrome’ for the last 3yrs, I’ll take it. It’s been a long time since I’ve seen the scale (albeit in small measurements) move in that direction.
And Joe thank you for providing such a credible venue for peer discussion on our experiences with this product. A lot of the forums out there have been cluttered with spam and other nonsense. I know, I check them all the time …and this is the only one I would bother commenting on.
Clearly there’s a huge interest in this product from your readers.
Hi Marisa
I honestly dont recommend zi xiu tang for teenagers because there are no studies on teenagers. Remember, teenagers are not miniature sized adults and may respond differently. if you look through the comments on this and my other zi xiu tang reviews you can see the side effects that people are experiencing.
I have two teenagers do you think it be safe for them to take?
T. There are no long term side effect studies on zi xiu tang. while many people commenting here say they get dry mouth some have said some more odd side effects like rapid heart rate and feeling like they crave zi xiu tang. Im not sure what to make of all of this.
Thanks Inertia i just emailed her privately what you said. hopefully that will help her. Thanks for the feedback!
I really would like to start taking these pills but I don’t know if I should. What about the long term side effects….Some feedback please…
No worries Joe – I know personally when I was researching this product I was suspicious of sites that mentioned sources, you never know who’s selling.
Having said that, once I decided to buy it I know how concerned I was whether I was buying from a safe source, with all the counterfeit warnings out there. Both the places I got them from in the U.S. and the place here in Toronto (which I just picked up from last night) I would feel comfortable with recommending.
If you’re comfortable with sending her a private note, you could tell her all I did was search “Toronto” and “Zi Xiu Tang” and the place will come up. It’s in the “Markham & Eglinton” part of town but because this is a residential address I’ll let those people tell her the specifics, for safety reasons.
Again, that is if that’s not compromising on your part. She is a fellow- Torontonian …just helping a girl out.
Inertia. thanks for the heads up. I was on the fence about publishing it since the person mentioned you specifically. I didn’t want to censor the message but since you mentioned it to me, I have removed it from the site.
Thanks for being my extra pair of eyes 🙂
Joe – Is that permitted on here, to mention a source?
(In response to Shawna’s note)
Thanks for the info Cathy.
Sorry to hear you gained back all your weight after stopping Zi Xiu Tang but as long as your blood pressure is back to normal and your sleeping well again thats a good thing.
Try just reducing a little food each day – say 250 calories. In theory, reducing 250 calories a day will lead to about 1/2 lb weight loss per week. In the end its about slow weight loss and being healthy 🙂
“Zi Xiu Tang face/figure and beauty capsules are created by Guangzhou Ziu Tang Bio-Technology Co., the #1 weight loss company in China today. Utilizing both TCM and Japanese Kanyo concepts for manufacturing.” Etc
This info was copied from a distributors web site as to where the product originated and is manufactured. I couldn’t do a copy paste due to security features implemented on the web site. HTH
P.S. I have gained every pound back as of today since being off of the pill (inches as well). I am however back to normal! Blood pressure is normalized, dry mouth is still a problem, and I am sleeping like a baby!
Cathy
Hi Ann. several people have reported dry mouth with Zi Xiu Tang. If you read through the comments you can see all that people say they have been experiencing. Read this review and my first review “Zi Xiu Tang Does it Work” for all of the comments to date.
Have you recently started exercising? Its hard to say but that may account for your charlie horse-like pain? Another option is whether you are drinking too much water. How much water are you drinking? There is a condition called hyponatremia. Being dizzy could be a sign of this. I suggest you speak to your doctor about the dizziness.
I have been taking zxt for about 8 months on and off. I do experience a very dry mouth and lately I have been getting dizzy on off. I do drink a lot of water but I still seem to have a dry mouth no matter how much I drink. I also have been getting foot cramps at night the painful charlie horse kind. The pills do control my appetite, I do go the bathroom a lot especially when I eat milk products I have no idea why it only seems to happen when I eat milk products. Anyway I have lost 35 pounds to date but I also exercise and follow Weight Watchers. Every time I go off of the pills my weight loss stops or I gain even if I eat exactly as I did while taking the pills. I can only tolerate taking one pill a day and I am scared to take more than one pill a day due to the bathroom affect and dry mouth. I am curious if anyone has lost a lot of weight with these pills and gone off them what happened after they went off the pills. I still have 20 pounds to lose and I am afraid if I don’t continue to take them I won’t lose anything anymore. The extremely dry mouth continued for me for over a week after I stopped taking them and that is scary. I am also wondering if the dizziness I am having is from my blood sugar being low or is a side effect of the pills. Has anyone stopped taking them for a long time and gained I need to know.
You got me curious so I just looked and it turns out I do have an big long number in a circle-shaped sticker on the back of my zi xiu tang bottle. It’s a long number, about 20 numbers long (small numbers, need a magnifying glass to read them). It also says the word “genuine” on the sticker. Guess I have the real deal after all? I still don’t see the name of the Chinese company where the zi xiu tang was made though.
Thanks for making me go look 🙂
Joe – I think the bottle you have is a counterfeit one. Just in the little research I’ve done, one of the identifiers to the authentic I’m pretty sure is supposed to be the authentication code printed in a circle on the back of the bottle (you scratch it off). You could google ‘zi xiu’ and ‘counterfeit’ and it should come up. I think one of the other signs is the smell of the product as well.
I didn’t see anyone else mention that on here. It would be interesting to know if their bottles had that code on it and how that related to their results.
Thanks for setting me straight Cathy (6 days not 6 weeks)
