Working well!
I bought these for a patient who had a stubborn case of neuralgia. He was experiencing numbness and tingling in both ankles for a year. After a couple weeks of taking Meridian Clear he began to have less numbness in one ankle.

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.

Works Like Magic!
My stomuch gets upset whenever I eat a lot of fruits. A few weeks back, I had a terribly stomachache, but fortunately, I have a bottle of Ping Wei Pan. I took some, and within 30 minutes or so, my stomach was completely soothed!
Yogi from Colorado
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!
Bettay100 from San Antonio, TX
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
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
Helped me a lot!

DebG from Greenville, SC
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
It works
I bought 2 bottles for my 19 year old son who's had bad breath not from his mouth or teeth or tongue. I suspected it's within his stomach digestive system. After taking the pills for 3 days I noticed the difference. No more bad breath.

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
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.

Shadow from California
Very surprised how fast and well this worked!
I have had increasingly severe dry eyes for past 3 years. It had gotten to the point I was using eye drops at least 10 times a day. Within four days of taking this herb my eyes are I guess you'd say-normal! I haven't used drops for over two weeks now
Rocky from St Paul, MN
Cleared up "strangling" sensation at night
At night, when lying down, I felt a strangling sensation from so much phlegm in my throat. My doctor gave me Mucusolve. I take 7 pills 2x per day. After the first dose I felt a lot of relief.
Jeriwho from Raleigh, NC
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.

A must for every household!
I first took this product hoping it would calm my nerves after I got in a car accident. It really helped and it had no side effects whatsoever. Whenever I am overly stressed or anxious, this product calms me right down. It calms kids down too.

Life Saver
My father has a compromised immune system due to chemo, so I have needed to stay healthy in order to be able to spend time with him and take care of him. Cold Signoff has worked extremely well and has been indispensable to me and my mother.
Grateful Customer from California
Great help!
my friend, who suffered the stroke recently, is only 35, so it was devastating to see him loose his speech and movement in his arm. After taking Strocontrol for only a few weeks, he feels much better and both, the speech and movement are coming back.

The formula...helps support my body's efforts to manage various types of "heat" signs. It's my first choice if I get a tickle in my throat or the typical signs of seasonal respiratory challenges.
OlyGary from Washington State
Makes a noticeable difference quick
I've been fighting to keep my heart strong and in rhythm for 5 years...It's made such a huge difference!!... I've only used one bottle and the difference is night and day. My heart stays in rhythm as well as a strong beat.

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.
