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.

I have tried many products in the last 10 years for sleeping related issues, but nothing compares to this product, you name it I have tried it, but I been using this product only for 3 weeks & I been sleeping way better than anything I had.
Excellent formula for Yin support
This is my favorite herbal formula; it addresses excess heat and/or dryness, kidney weakness and general aging. Noticing a big improvement in skin, especially reversing dry chapped lips. I've been using it over the years with great results.

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.

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
This WORKS!!
I bought this a month ago and my knee has never felt this good. I am a martial arts instructor and speed/agility/performance trainer, so I need my legs feeling good. This has helped me quicker and better than any joint supplement I've tried.

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.

Prior to taken LiverSmoothe I was taking various over the counter antacids several times a day and even awoke at night due to discomfort to take an antacid. I have not taken any in two weeks now and do not wake up with acid indigestion.

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!

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.
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.
Narayana from Oakland, CA
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
WORKED EXACTLY like my herbalist said
I've felt more grounded and calmer, and my energy has been MUCH more directed/focused. I have a lot of heat I need to expel, and it's been helping with that as well.

Cooling off
I am 64 years old and have been hot flashing every 2 hours everyday since I turned 51. Nothing seemed to help until I started using Yin Vive Cool and Menoplease. Now I only hot flash once at night. I can finally get some sleep. Thank you.

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

Quality Assurance

Our proprietary technology results in products with the highest possible extraction ratio, and we never add any pharmaceuticals, dyes or sugar. Little binding agents are added, so you never see the long list of inactive ingredients often found in other herbal products and dietary supplements on the market. 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.
