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

- Green tea
- Rhubarb
- Aloe
- Cassia
- Astrigillis
- Polygonum multiflorum
- Lotus leaf

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.
Joe says
Debbers, I’m glad zxt has worked for you. I just wanted to toss in my 2 cents to reiterate what I mentioned before that zxt headaches can be a sign of drinking TOO MUCH WATER. Its called hyponatremia.
Other than caffeine I don’t see anything in zxt that boosts metabolic rate. Actually metabolic rate decreases when we lose weight. This is why its often harder to lose that last 5 pounds.
As for vitamin D, some research finds many people are low in vitamin D3. I doubt if zxt lowers vitamin D levels.
melissa says
I’ve only been on this stuff for three days now. I am eating less, and I have more energy, and yes I am going to the bathroom more frequently than usual, as well as drinking more water. I have noticed a change in the way things smell. All my chapsticks, my perfume, my baby’s lotion, my toothpaste and a bag of grapefruit and oranges…smell very offensive. I can’t figure out what ingredient they all share, but they all give off this funny burned skunky smell.
Is this something that anyone else has experienced with this product? About 4 days before starting these pills I was taking Chantix (for almost 2 weeks). I thought maybe the smell change was from not smoking, but I don’t really think so. Can anyone shed some light??
debbers says
To the people who get headaches… if you are not drinking enough non-caff liquids, at least 1/2 your body weight in oz, this happens a lot. If you take pills within the first 1/2 hour of waking, most of the sleepless night issues go away. Make sure you stay away from stimulating foods, and liquids 3 hours prior to sleep. No choc ice cream before bed… sorry! When you boost metabolic rates, its harder to shut your day/mind off. Some people take Melatonin to help this, check with your Doc ! I have heard many people coming back with Vitamin D3 levels lower than normal, especially in women. Be careful, this is important for avoiding early onset of memory/neuro problems, and bone health. Always advisable to have a blood panel /physical before taking. Retesting after a 10% weight loss is typical, to re-evaluate meds. People with auto-immune issues should take special care. THERE IS NO MAGIC PILLS!!! But, responsible, knowledge based users, will have success!
debbers says
I have been taking zxt for 2 years. Taken off and maintained a 28 lb loss. There are ALOT of fakes out there!! On the front of the bottle should be a “R”. if it says “TM”… fake. The bottles of 48 are no longer in REAL circulation. an 18 digit security code is fake on the scratch off, should always be a 20 digit. Beware anyone selling on EBAY. The pills may be real, but may be expired, stored at bad temps, etc! I would recommend, researching a local rep in your area, holding a box in your hands to check authenticity yourself. Someone that sells bottles, but not enclosed in a sealed box.. IS FAKE! Average selling price for a single box is $45-60. If your paying less….buyer beware! Someone under the age of 19 is NOT ADVISED! Increasing metabolic rates, whether its from a stimulant or not isn’t good for kids who are still growing, this can interfere with regular fat/muscle ratio that’s important if the growth plates haven’t fused completely!
lin says
I have been taking these pills for 3 weeks, have increased appetite, constipation, cotton mouth and have not lost a pound. I must have a fake bottle also.
Denise says
Personally I don’t think cotton in the bottle has nothing to do with it…My first bottle had cotton in it, the code was authentic, and it worked. Now it’s a different story.
Joe says
Hi Kristen,
based on what people have been reporting, even authentic zxt no longer seems to be working in some people. If this is correct, the quality control is getting bad.
If you entered the authentication code correct and it said the code has already been used, then that’s another sign that the quality of zxt is fading fast. Remember China is very much a 3rd world country. Quality standards for supplements may not be as universally used as those in the US. Has anybody ever seen the china plant where zxt is made?
I would not worry about if zxt has cotton in the bottle or not. That is no proof of what is authentic zxt or counterfeit zxt. I understand your frustration and I share it also.
Kristen says
I just ordered a bottle and I was doing my research I read that authentic bottles do not have cotton in them is this true? I went to the site and entered my code it said this password has been used more than once buyer please be cautious of purchasing counterfeit products
Meka says
I think I’m going to stop taking these pills!!! its a waste!!!!!!! I dont feel any thing! I will stop before i end up messing up my system.
Jenn says
Hi All, I have been taking the pills for 3 days now, I am not able to go to the bathroom, I have headaches, my appetite actually increased! I just received a bottle today from Floyds, could these be a “bad batch”?
Joe says
Denise thanks for your kind thoughts and sorry the product isn’t working anymore for you. Don’t be discouraged. Remember to stay on target 🙂
Denise says
Hi All,
Now we are stuck with bogus pills!! I have been on them since January (1st bottle which worked). Purchased 2nd batch (3 for 90 – taking 2 per day on 1st bottle), input code and received a different message to contact a Mr. Tom..I have also realized that this 2nd batch is not working as the first. I do hope out of the 2 bottles left, one of them is authentic. If not, I will not be purchasing again. I have truly appreciated this site, and Joe for keeping us informed.
Joe says
Marina, thanks for the clarification. Ive said all along that senna was one the key ingredients in zi xiu tang. the removal of that (plus anything else they dont list on the label) may be factors in zxt not working.
Marina says
Hi Joe,
They did not admit that they pills were fake. They stated that they received several complaints about their latest batch. Now, I am also wondering, if the removed Senna ingredient made a difference in the effects of these pills.
Joe says
Marina thanks for letting me know about that. So Floyd Nutrition told you the zxt was fake. Im sure Floyd doesn’t make zxt; they get it from a company that puts the pills together. This is likely in another country and who knows what quality control they have. This probably happens more than we know when we deal with companies outside of the country.
Gift says
Just started taking ZXT today. Will weigh tomorrow morning and start a journal of weight loss (if any) and other physical changes. Thanks for all the straightforward remarks and comments.
Marina says
Hello All,
I have been using these pills on and off for 2 years. The latest batch I ordered from Floyd Nutrition turned out to be fake. Floyd Nutrition admitted that they have had several complaints and sent me a replacement batch which also turned out to be fake. I am not sure what happened, but I think they changed the suppliers and the issue is there. The pills have gotten cheaper over the years. I am also resell these to people I know and had to stop, because I do ot want to resell something that is not authentic. FYI – the codes that you enter on the website can be bogus and will still come up as real, so I would not go by that.
Amy says
Hi everyone, I’m new to the site but I’ve been researching ZXT for a while. I’ve been taking ZXT for 11 months, I lost the weight I wanted to and have continued to take it solely because I can eat what I want and not gain the weight back. I haven’t lost anymore weight with the continued use. I’m starting to get concerned though as I have noticed possible long-term side effects.
Every few weeks I will have spells of vomiting and diarrhea in the middle of the night (usually about 5 hours after I last ate). The spells are horrible and last for about an hour, followed by exhaustion, but by morning, I’m fine. I also get headaches, almost every day. Nothing makes them go away, water, medicine, it’s no fun. I’ll also notice that if I go off them for a few days, I can’t go to the bathroom. I’ll be horribly bloated which made me realize that I have most likely because dependant on the laxative effects of the drug. And most recently sever muscle cramps, usually starting in the arches of my feet.
I don’t know if all or any of these things are related to the ZXT, but I have to imagine they are. I’m just hoping it’s not causing any sever damage. I know it’s terrible, but I would endure all of these things to be free of the constraints of dieting and the weight struggle of I have dealt with all my life until now..
Has anyone else used the product as long as I have?
Sammy says
Hey guys! On my fifth pill out of twelve. Having some sleeping problems such as waking up in the middle of the night once or twice and not being able to FALL asleep for about 1-2 hours.
Appetite is a BIT decreased and bowel movements are the same as yesterday. On April 1, I started at 155. As of now, I am 153.4lbs!
I have changed the way I eat completely by eliminating all junk food such as chips, white bread, sodas, and desserts. I use to eat 3 big meals a day but after researching and snooping around, I found out that eating six small meals a day helps keep your metabolism high and burning calories!
Meka, I wish you luck. Although they tell you not to change your eating habit, I think eating a more healthy lifestyle will add a definite boost in weight-loss. Try reading The Abs Diet: The Six-Week Plan to Flatten Your Stomach and Keep You Lean for Life by David Zinczenko. This book helps you choose the right decision in eating the right foods.
Meka says
Hey heather, I worked a 8 hour shift today and felt no different. I am on my 3rd day.. Still nothing 🙁 THe other problem is i never had a problem with pooping. I usually poop at least 2 to 3 times a day anyway. But i was hoping my poop would increase from solid poop to a liquid kind of uncontrollable poop!!! Well im glad it isn’t uncontrollable. But at the same time i have not felt any different. My energy level is still the same. I been taking multi-vitamin pills so maybe that’s why! Not sure but i would like to be able to tell that its working 🙁 Ill be on my 4th day tomorrow! I will weigh myself on the 5th day just to see if i lost at least 1/4 of a pound!
