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.
Just wanted to give everyone an update as I did tons of research about this supplement before starting, and I’m sure others are also! I will admit that my first few days of taking ZXT were not the best.
I was super hyper, woke up in the middle of the night, and used the bathroom A LOT! As I’ve now been on ZXT for a little over a week, I am noticing a definite decrease in those side effects. I still have more energy than usual, but I am no longer waking up overnight. My trips to the bathroom are also decreasing.
As a person who eats pretty healthy, and exercises regularly, there are a few specific things I have noticed. First is that I definitely eat a lot less. Second, I notice a definite decrease in cravings for chocolate/sugar. I used to crave sweets on a daily basis! Third, I’m thirsty for water ALL DAY. I have been drinking at least 6 bottles of water per day.
After 8 days of taking these pills I have lost 6lbs. I honestly think this is due to a combination of eating less, continuing my regular exercise, and the laxative effects (mentioned by Joe) in many of the ingredients.
My only question, for Joe, is about the appetite suppression. Any clue what is causing this?
Thanks Tisha. I’ll look forward to your updates 🙂
Hi Joe, I am a little skeptic about diet pills but I have friends who stand behind this product 100%. I gave it some thought and said what the hect I’m willing to try them. Today will be my first time taking the pills. I am also on a 2000 calorie diet as well. My realistic goal is 12lbs. I will give feedback every couple of days to keep you posted. I know that everyone experience is different. I will record any side effects or changes that i recognize, if any. Thanks Tisha
I’ve been taking my pills for 3wks now and for some reason the effect I experienced when first taken them has WORE OFF!!!!! The pills just seem to have stop working! No more extreme thirst, no more burst of energy and today I’m craving sweets!!!!!! Has anyone else experienced this? I’m feeling cheated!
Vicky: I would not start out by taking 2 pills. I would take only 1 in the morning. Until you know how your body reacts to it, it’s better to be safe that way. Additionally, I would also recommend that anyone considering taking this product consult your doctor prior. I did and was OK to take it, but that may not be the case for everyone.
Hi Christi
thanks for letting me know about that.
when I survey the published peer reviewed studies in the national library of medicine I do not see any research on bee pollen and weight loss. Now, that does not necessarily mean that bee pollen does not work, rather, only that nobody appears to have gotten around to looking at bee pollen and weight loss.
That said, since zxt has bee pollen and since it’s heavily marketed as a weight loss supplement, I wonder what research the zxt sellers have that I do not. its quite possible that they do know something I dont. I just would like to see that evidence.
Jeggs, thanks for letting me know about your zxt side effect. As this point I’m not sure what part of zi xiu tang caused sexual side effects or testicular shrinkage. I am glad everything corrected itself.
I’d like to hear from more men to see if they also had sexual side effects to see how prevalent this issue might be.
Hi Joe,
I took ZXT last summer for a couple of weeks to lose a few pounds that i had gained during winter, it worked i lost about 12llbs. However with all the normal side effects, loss of appetite, thirst etc. I also experienced loss of sexual desire and testicular shrinkage, i noticed another guy had experienced this and was waiting to see if you had found anything that may cause this.
After a week or so these side effects were gone.
Thanks for the insight btw.
I am interested in this supplement. By reading all the side effects, I am re-thinking my purchase.
I have been reading about this product for a few days, and trying to find out different information on it.
I don’t want to risk my liver, or my eye sight, or blood pressure for weight loss.
I wonder, has anyone taken the supplement, let’s say for 6 months, lost the weight…than continued on healthy eating, etc, and still gained the weight back?
I know everyone’s body reacts differently, that is why I wanted to see how my body would react in the first week or two.
I was told if I purchase them, to take 2 supplements in the morning before 10 am, that way it doesn’t interrupt my sleep. I like having my 7-8 hours of sleep, so hopefully it works out.
Thanks
Joe,
Yes, I did and it came highly recommended. I gave the name “wellness doctor” because I didn’t want to mention anyone else’s name or business on here without their permission. Yes, I did purchase it thereafter.
I totally respect your investigation, however as an attorney, my defense is this: As you state there are no scientific tests proving that this product does work or that bee pollen is effective with weight loss, are there any tests proving that it does not?
I know that exercise and diet alone would allow me to lose weight. However, with 3 kids, a business and very busy lifestyle, this product gives me a boost of energy. By the way, I did take this product to my family doctor prior to starting and he indicated after reviewing it that he would start with taking 1 per day and see how I personally reacted to it.
Sorry if this is long winded but I just lastly would like to say that just by taking 1 pill per day of anything without diet and exercise is healthy or going to miraculously help you lose the weight you desire. I have learned that losing weight is your own minds will and challenge-you have to want it that bad for yourself-what you give is what you get. So, if you are having problems with this product or any product out there or just do not feel comfortable taking products, DIET and EXERCISE it works-but you have to be faithful everyday.
Hi Christi,
Im glad you have been exercising and eating better. What is a wellness physician? did you get your zi xiu tang from a medical doctor (MD or DO)? Just curious as I have not heard of doctors giving out free samples of weight loss supplements before. Can you fill me in more on this? after you got the sample pack, did you buy zxt from that doctor?
I would just like to add that I am 30 years old and was given a sample pack by a wellness physician. I liked the sample. I then purchased the normal bottle. I have been taking it for about 1 month. I have lost 6 pounds. I have had none of the side effects mentioned, nor does mine list senna or casse or any of the like ingredients. I do notice some increased energy. I was told to take 1 pill per day in the morning. That’s what I do. In addition to taking this pill, I have started dieting and exercise 1 hour everyday doing tae bo faithfully. Everyone is different and not everyone will have the same reactions.
Hi Patty. Im glad things are working for you and that you have not had any of side effects others have reported with zi xiu tang.
I dont know why everybody should react differently especially since some supplements are very expensive. People tend to accept that with supplements but if anyone said that about a drug people would flip out. I believe supplements should be more than a crap shoot. we should know what is in them and they should all contain the same thing. my 2 cents, maybe worth less than that in this economy…
I have been taking the pill as directed for a month. I have lost around 10lbs. I do experience the headaches and the occasional diarrhea sometimes. I have not had any of the other side effects. I notice i dont eat as much i get full faster. I have no problems sleeping i work nights and i take them when i get home in the morning and go straight to bed i sleep all day. Everyone’s body is different and these pills are going to work differently for everyone. I like them its hard for me to lose weight and this is working for me.
Susan,
I would stop taking zxt today and not use it anymore. The symptoms and side effects would scare me also. I dont want your vision blurring or you getting when you are driving. I don’t like that your blood pressure has gone up (did you test it yourself or did your doctor?).
I recommend you go to your doctor this week and get checked out. that will at the least give you some relief since I know you are having some anxiety over all of this.
If you go to your doctor let me know what he says.
I have been taking zxt for 21 days now, 2 pills a day in the morning. I have only been sleeping 4 hours a night, have bad dry mouth, severe headaches and this week my heart started palpitating and my bp went up to 194/93. My whole body aches and I get very dizzy and my vision blurs while I am at work typing on the computer or writing. I already lost 70 pounds on my own over the last 2 years by cutting down my portions and eating more fruits and salads and trying to stay away from sweets (hard when you have kids). My mom’s friend told me about zxt because her granddaughter used it and lost 30 pounds in a month. I have 30 pounds left to lose and did lose another 14 pounds with the zxt. I read the pamphlet that came with my zxt bottles and it says to take 1 pill for another month before going off of it. I only took 1 pill today and still have a bad headache. I would prefer to stop taking these pills tomorrow but was just wondering if you think I will have more side effects if I stop cold turkey?
Hi Sandy
some people inform me that new formulations of zxt may not contain senna. Here are some other names that can refer to senna
Casse, Fan Xie Ye, Séné d’Alexandrie, Sen and Sennosides
I am just wondering, I am checking out this supplement and hear a lot of talk about Senna but on the ingredient list on this site I do not see senna listed, is it called something else?
Anthony, thanks for letting me know about that. Glad things are back to normal. Its very odd what you said about zi xiu tang. Most people who use it that Ive run into are women
I’m curious if any other men had a drop in sexual desire /performance after taking zxt?
Just a quick update…i stopped taking the zxt about a week ago, after experiencing a drastic drop in my sexual desire…the good news is that after about 3 days off the stuff everything returned to normal
