It Works! Hard to believe but true
I have had problems with my balance for many years and it’s gotten increasingly worse. The feeling would be of lightheadedness... I started taking (it) just a short while ago and my balance and my feeling of connection to the earth has returned.

One Year Later - Great Results
Don't know what I would do without this stuff! I was having hot flashes followed by chills, sometimes 2-3 times an hour. Miserable! Er Xian Pian was recommended by a TCM specialist and I am so glad it was.
Friendly Mum from Canada
Best liver formula
I can't say enough good about this formula... The liver deals with emotions and especially anger, so at first I had to watch not to get in irritating situations. Having used it over a month now, I see more of a balance emotionally.
Mayisha from Fernandina Beach, FL
Works for me!
The Stonepass product from Active Herb works better for my slow drain issue than anything else I've tried. Seems to give relief after only couple days, is very economical.
Spaceman from AZ
Lung Vigor is healing, and a productive herb recipe. I notice immediate results. I could breathe deeply, and felt I could take a full breathe of air without any tightness or constriction in my chest.
Great product that works!
I bought these tablets less than a month ago. I had minimal cramping during my cycle and I ovulated to!!!
Abenagha38 from Georgia
Excellent product, works very fast
I've been dealing with 'plum pit throat' for several years, and even acupuncture treatments wouldn't resolve the phlegm and feeling of something stuck in my throat. After taking about six bottles this ongoing problem was finally resolved!
SpiceGirl from Earth
Trying alternative way
I have rare neurological condition and this formula was suggested to me by practitioner of TCM. So far my blood pressure was normalized and my sleep improved. So far, so good.
Natalie from NYC
I could feel the difference
It did what it said it would: give me some peace and calm in a very stressful time. It seemed to take everything down a notch to "Ok, I can handle this." That felt really good.

Clears Head
I've used this every time I get a clogged head, cold, sore throat or even stiffness in my neck and it really works!.. It really works fast! Love this product, won't be without it!
DebG from Greenville, SC
Clears Heat
When I use the product as directed it helps clear any heat related problems like canker sores, and annoying teeth marks inside the mouth. I will reach for this whenever I seem to have a pitta or fire imbalance

Spleen strengthener
If you are struggling with poor digestion and edema especially around the midsection, this may help. I’ve noticed much digestive improvement after taking these.
Jay from New York
Long term stamina
I was chronically kidney qi deficient from staying up late many nights causing me to be exhausted and dragging. This helps keep me going without the exhaustion.
Unami from Midwest
Completely surprised!
My hip had been a source of discomfort and pain, even in my sleep. Just the simple act to rolling over in bed was an awakening experience. I can honestly say that I’m able to move more freely with less discomfort, and my sleep has gotten way better.
Nelson from Southern Vermont
This formula helps!
Whenever I feel the Liver Qi Stagnation coming on (frustrated, stiff neck, negative outlook on life, tense) I take the recommended dose on the bottle and within a few hours I am feeling much more relaxed. By the next day I'm feeling normal again.
BBrownOrg from Amherst, WI

I bought this for weight control. Haven't seen much change in that area. To my surprise! It has really cleared up skin, regulated my bowels, which has given me energy.
Kajia from Omaha, NE
Exceptional results!
I have been taking Breathmooth for a few weeks and already experience much less congestion. I can breath more deeply and easily and I am delighted to have found a natural remedy that 'works'.
Terry33 from Westport, CT
The best ever remedy
my enlarged prostate seems to be gone because urinal flow and morning highlight are all back. I used several methods over the past 10 years, all helped some but Prostate Sure is without a doubt the best and most helpful remedy I found.

Food coma pill
When you have food coma, this is your friend. When you’ve eaten too much and are full of regret, literally and figuratively, this is your friend. When you feel like that food is just sitting in your stomach and not going down, this is your friend.
Jay from New York
Works for me!
I've been taking this supplement for a while now and I hardly ever get night sweats anymore. My hot flashes are also much less frequent. Highly recommend it!

Get to sleep and wake up energized!
A few times a year I have sleep difficulties that last for several weeks. By taking the recommended dose I can fall asleep easily and when I awake I feel absolutely energized, which is something you can't say about other sleep aids.

Product that actually works
This is the very best product I have found to clear my sinuses and keep them clear. Would not be without Bi Yan in my medicine cabinet.
BillS from Sun City Center, FL
93 yr old mother vision improved!!
"you know what, I can read the subtitles without my glasses! I could never read them before without my glasses!" We've been giving her 7 to 8 pills 3x a day for just over 1 week!!! I am thrilled that she is already experiencing results.
SuperD from San Francisco, CA
Great Product!
I had bad cramp and whole body uncomfortableness every time I go through my period for many years, after I took this pill for a month, all the symptoms are gone. Now I can enjoy my NORMAL days while I go through menstruation.
EllenT69 from Fairfax, VA
Good quality, a potent formula
I would classify as being on the extreme (Yang deficiency) (feeling cold in the body as well as the limbs, emaciated, underweight). So I decided to try YanVive Plus, and was surprised at the difference. It was much more potent than expected.
My gallblader meridian has been stagnant for a long time and this product opened it up after nothing else gave sustained relief!
Immune strength plus more
I’m glad my alternative doctor advised me to take this product during this past year. I know it has helped me stay healthy.
ShontaSamere from Florida
Great product
When digestion begins to suffer, I take 6-7 pills and feel immediate effect half hour later. Takes care of after-meal cramping and that rush to find a bathroom. Warms the digestion and eases stomach bloating associated with food consumption.

What is it?

Guang Ci Tang®(广慈堂) has been a leading US brand of Chinese medicine since the 1990s. Guang Ci Tang® Chinese medicine products are 5X concentrated, more than double the strength of similar products from other leading brands. Guang Ci Tang® Chinese medicine is guaranteed to be the best of its kind in terms of strength, purity, safety, and affordability. Each product has been carefully produced in a cGMP-certified facility and fully tested for safety before it reaches our customers.

Superiority of Guang Ci Tang products starts with their formulations. As anyone who is trained in Traditional Chinese Medicine may tell, a right combination of herbs is crucial to the success in practicing Chinese medicine. Often than not, products bearing the same name have different formulations both in terms of the variety of Chinese herbs and the dose of each single herb. Guang Ci Tang has experts who are masters of both Chinese medicine literature and Chinese medicine practices. Many formulas Guang Ci Tang develops have their own uniqueness that may maximize their efficacy.


Chinese herbal formulas play a central role in the theory and practices of traditional Chinese medicine (TCM). Many formulas were invented one thousand years ago and remain widely used today as an integral part of China's national healthcare system. These classics are truly time-tested for safety and effectiveness. We are proud to inherit these treasures and feel honored to share them with you.

As our society faces many modern health challenges, Chinese medicine is constantly evolving to combat them. Our team of scientists and TCM doctors stay abreast of the newest research and breakthroughs in both TCM and modern biosciences. Then we incorporate that newfound knowledge into the development of our signature formulas that address many contemporary health issues. Guang Ci Tang currently offers over 100 Chinese herbal formulas.


To meet our strict quality standards, Guang Ci Tang® products are manufactured in collaboration with some of the largest and best pharmaceutical companies in China, in state-of-the-art cGMP certified facilities. Only premium quality Chinese herbs are used. The botanical identity of each herb is verified by our expert professional staff based on the accepted standards set forth in the Pharmacopoeia of the People’s Republic of China (PRC) to ensure authenticity, quality, potency, and safety. Furthermore, many Chinese herbs must be processed in highly specific ways to achieve the desired medicinal properties or to eliminate toxicity. At ActiveHerb, we take care to perform these preparations in accordance with the TCM tradition.

In order to produce Guang Ci Tang® tablets, herbs are first thoroughly cleaned, then mixed together and extracted in water in a steel extraction tank. This process follows the ancient practice of decocting Chinese herbs in a pot, but allows precise control over the extracting temperature and time. The modern extraction process reproduces the traditional method to recover active ingredients, but has been shown to yield a superior degree of potency. Essential oils, which typically evaporate from the herbs during heating, are automatically recovered through the extraction process. After extraction, herb residues are discarded while the extraction liquid is recovered and pumped into a condenser. Here, the remaining water is evaporated, leaving a highly concentrated paste. This paste is turned into tablets or teapills by adding a small amount of dry powdered herbs from the original herbal formula. In this way, we avoid the use of unnecessary binders and ensure the purity of our products.

The state-of-the-art quality control center. Extensive laboratory testing is done here to ensure compliance and quality.

A manufacturing room is seen from the hallway and is equipped with advanced instruments. In order to access the manufacturing rooms, one must change into another sterile coat and shoes before entering.

The entire cGMP facility is a completely clean environment. In order to access to the entry hallway, one must wear a sterile coat and shoes. The manufacturing rooms are located along both sides of the entrance hallway.

5:1 Concentration

The standard PRC Pharmacopoeia procedure for producing concentrated Chinese herbal pills is based on a concentration of 2:1, meaning that 2g of raw herbs will yield 1g of finished pills. These pills weigh about 180mg each. Each dose requires 8 pills, which weighs 1.44g total and is equal to 3g of raw herbs.

Guang Ci Tang® strives to be the most potent and effective Chinese medicine available. We developed proprietary extraction and concentration technology that allows us to make our tablets and pills at a final concentration of 5:1, meaning 1 gram of tablets or pills is equal to 5 grams of raw herbs. As each Guang Ci Tang® tablet or pill weighs 200mg, each pill is equal to 1 gram of raw herbs. This is the highest concentration available for Chinese medicine pills and tablets, and is more than double the concentration of standard pills from other leading brands of Chinese medicine. As a result, patients are able to reduce the number of pills required per dose by half to achieve the same powerful effect.

Tablets vs Pills

Traditionally, Chinese herbal formulas are served in liquid (Tang) after being cooked in water. The pill form (Wan) was developed when the Chinese pharmaceutical industry started to produce traditional Chinese herbal formulas at higher volumes. Pills are now produced by every TCM manufacturer. While Guang Ci Tang® also produces round pills, our flat tablets (Pian) truly exemplify our commitment to excellence and innovation, and set us apart from the rest. Guang Ci Tang® tablets are uniquely made with proprietary technology that requires little use of a binding agent. Tablets made by other Chinese medicine brands frequently include large amounts (up to 50% in some cases) of inert ingredients, such as magnesium stearate, which are mixed with the herbal extract. Guang Ci Tang® tablets are more expensive to make but they have the advantage of being easily absorbed by the body. Moreover, our tablets may also be administered as a tea after being dissolved in water, or may be given as a powder after being crushed.

1 tablet = 1 gram of raw herbs

1 teapill = 1 gram of raw herbs

Our proprietary technology results in products with the highest possible extraction ratio, and we never add any pharmaceuticals, dyes or sugar.

Comprehensive tests for heavy metals and microbes are conducted for each batch of finished products by independent laboratories in China and the USA, in accordance with the guidelines established by the U.S. Pharmacopoeia. After all, it is our longstanding commitment to quality and safety that has built Guang Ci Tang®’s reputation as a leader in the industry.
