DebG from Greenville, SC
Works wonders!
Before starting taking these, I would have hot flashes all during the day and nighttime was crazy. Now I have maybe 2 or 3 during the day and some nights I don't have any at all.
Miran from Georgia
Working so far!
I have taken two bottles of Tumoclear so far and my sebaceous cyst on my head has significantly reduced in size. I have ordered 2 more to see how it goes. I'm impressed. I have tried everything for my cyst and to no avail.
Brett from Rocklin, CA
The title is a good choice for the product.
it has done a great job of eliminating the relatively small amount of fluid retention that I was experiencing. I was waking up with puffy eyes and after taking this product for several days, I found that most of the puffiness under my eyes is gone.
Vonnie from Oracle, Arizona
Work well with no side effect
My husband has neck and shoulder tension when he gets stress out. He takes 10 tablets of Corydalis Relaxe and the tension will go away in an hour. However, if the stress is intense or the tension come back later, he would take another 10 tablets.

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.
BBrownOrg from Amherst, WI
It Works!
Within the first couple of days I noticed less hemorrhoids bleeding, itching and inevitable soiling happening. A week later it was reduced by 80%... Now, about a month later, I just use one recommended dose every other day.
William from South Lake Tahoe, CA
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 fast!
Neckinder works wonders and very quickly! I can take it once, and feel relief from my neck pain within the hour. If I have a flare up of trapezius and neck tightness and soreness, taking this twice a day usually 8 at a time works wonders.
Jani from Calgary AB
It works!
I have been using Yin Vive Hearing for about 3 months when I first discovered I had ringing in my ears with a loud screech every day, once a day. Now I am delighted to report that the screech is 95 percent disappeared, the hum is barely there.

Wonderful product!
This is a wonderful product. It seems to keep me calm and relaxed and definitely helped to normalize my pressure. Another benefit was that it decreased the redness on my tongue.
Sb32 from Florida
Wonderful relief
My naturopathic doctor recommended these in pill form for uterine prolapse. It takes a while to get relief, probably 3 bottles need to be taken first, but when this kicks in....the results are extremely good.
Mtngram from High Country, CO
Good for cooling-down anger
I had a difficult situation at work that angered me for a few months, but even after the situation resolved, I found myself prone to anger... After using Liver FireClear formula for a little over a month,,, I find my cheerful attitude has returned.

Awakens vital energies
I have been using this product for the past 2 years. It has revived vital energies and boosted romantic endurance. This is a far better option for men than a rx medication. No negative side effects and started working after one month.

Since taking this herb my mind is alert, and able to intake large amounts of information without feeling tired. There is a noticeable difference when I don't take this herb. I go back to feeling like I haven't rested enough.
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

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.
