Yan Hu Suo Zhi Tong Pian (Yan Hu Suo Zhi Tong Wan, Corydalis Relaxe™, 延胡索止痛片) is a Guang Ci Tang® signature formula that includes Corydalis as the main ingredient for pain management. This Chinese herbal medicine is our choice of all natural dietary supplements for general pain management, whether pain is chronic or neuropathic, as long as Qi obstruction or Blood stasis is manifested.
Life is pain. Pain is the most common reason for doctor visits. Chronic neuropathic pain alone affects over 50 million people in the USA. Pain is managed in most cases by the nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen when low or moderate pain exists. In cases of severe pain, opioid drugs such as morphine may be used after prescription. While opioid drugs are potent painkillers, they develop drug tolerance and physical dependence among other side effects. These conventional analgesics are less effective for neuropathic pain.

From the perspective of traditional Chinese medicine (TCM), pain is caused by obstruction of Qi flow or blood circulation in the affected area. Qi is a vital energy circulating in the channels around our body. Many Chinese herbs are well known in TCM to move Qi energy and invigorate the Blood and thus relieve pain. Yan Hu Suo (Corydalis Rhizome) is one of such Chinese herbs. Yan Hu Suo Zhi Tong Pian (Corydalis Relaxe™) is a Guang Ci Tang® signature formula that includes Corydalis as the main ingredient and several other Chinese herbs that reinforce the action of Corydalis.

Yan Hu Suo in TCM acts to invigorate the Blood, smooth the Qi flow, and alleviate pain. Pain management is the most conspicuous aspect of its action. Chinese herbalists have found that Yan Hu Suo is applicable to pain in a wide range of conditions and is potent compared to other Chinese herbs. Yan Hu Suo also has a good safety profile in its action. It does not induce tolerance and physical dependence, another big advantage compared to the analgesics on the market.

Scientists have worked hard to reveal how Yan Hu Suo works in modern biomedical terms. Several analgesic components have been isolated from Corydalis. A latest research that is published in 2014 and widely reported by media including Dr Oz show nicely illustrates such an effort. In the study1, scientists from China and America are able to identify DHCB (dehydrocorybulbine), a Corydalis component, as an analgesic that is effective against thermally induced acute pain, inflammatory pain, and injury-induced neuropathic pain. Furthermore, it does not cause antinociceptive tolerance. In contrast to morphine, DHCB's antinociceptive effect appears mediated by dopamine D2 receptors but not opioid receptors. It should be noted that besides DHCB, other Corydalis components like I-THP (L-tetrahydropalmatine) are also shown to act the same way to alleviate pain. These results are in consistence with what we have known in TCM about Corydalis for centuries.

In addition to Yan Hu Suo, Corydalis Relaxe™ includes 3 other Chinese herbs, Bai Zhi (Dahurian Angelica Root), Xiang Fu (Cyperus Rhizome), and Chuan Xiong (Sichuan Lovage Rhizome) to further enhance the action of Yan Hu Suo. Here, Bai Zhi disperses Wind and alleviates pain in the head region. Xiang Fu promotes Qi movement, resolves depression, regulates menstruation, and stops pain. Chuan Xiong is another famous Chinese herb that invigorates the Blood, smoothes Qi flow, and alleviates pain. It also expels Wind.

Corydalis Relaxe™ is our choice of all natural dietary supplements for general pain management, whether it is chronic pain or neuropathic pain. It is especially recommended for pain caused by Qi obstruction or Blood stasis in cases of pain in the stomach, frank region, head, and menstruation.

    Amazing pain reliever

    This is the second time that I ordered Corydalis. I take it when my prescription pain meds are not effective for my chronic nerve pain in my feet. It helps a lot to reduce the severe pain to mild and tolerable. I'm so glad that I found this.


    my chiropractor recommended this product for my restless legs, and i am very grateful. it's wonderful to be able to sleep through the night!

    interesting product

    i dont really feel painkilling effects but i feel it helps when it comes to sleeping

    Excellent Results!

    Neuropathy pain caused by a neurodegenerative condition was completely put in check when common prescription meds were no help. We love this product so much we wrote a blog post "Neuropathy Chronicles" detailing just how pleased we've been. It does take some time to work but the wait is worth it.

    Great help!

    Last year I went for a full mouth dental implant restoration. The maxillofacial surgeon drilled my upper and lower jaw, four times each. The next day, my face was a swollen mess, to the point that my husband jokingly said that I looked like Rocky Balboa. My doctors at Clear Choice had prescribed Vicodin, but I refused to take it. I did try Corydalis. I took 8 tablets, then another 8 and the pain was considerably reduced, to the point that I asked my husband to go to the police station and leave the Vicodin there. I always keep two bottles of Corydalis at hand for when they are needed.

    Not what I had hoped for

    Well, this stuff doesn't help me relax. I like the smell and the size of the tablets. Mostly what it does to me is give me really intense dreams.

    Corydalis Relaxe

    This product is doing something for me for the good. I can't explain it, but I am feeling much better.

    This works!

    This is my second purchase of this product. It is the only thing I take for the constant pain I have. It works really well. No side effects.

    good for facial pain

    I take this herb for tri-geminal face pain. It helps when taken at first symptom.


    Most herbal formulas will take about two or three weeks to have noticeable effect, but this formula worked in two days of taking three times a day. I have pain in lower back, knees, feet. After taking this formula I felt noticeable relief.

    It works as advertised

    I have problems with pain in my shoulders, making it difficult to sleep. Over the counter pain killers didn't help. This product works great and, so far, without side effects. It doesn't affect my blood pressure, either.

    poor Quality

    I have no idea what this is but it's not the Corydalis I'm used to nor does it work, this might be cheaper than other brands but there is no value in it either. complete waste of money.

    Does well for acute pain

    I have been using this Cordyalis for a few weeks & was surprised at how well it helps relieve pain & inflammation. I would recommend this to anyone with excruciating Arthritis pain for both Rheumotoid and Osteo. I unfortunately have both & over the years pain has gotten unamanageable. This works if you take 6 tabs three times a day, and add their Joint Joy with it. I'm so grateful to have found some help. I refuse to take any pharmaceuticals whatsoever.

    is not that strong


    Surprisingly affective

    I have had fibromyalgia since 1997 and have tried almost every "western" medication for pain. All have been ineffectual for pain relief and have had many severe side affects. I have been using corydalis relaxe for about 4 months (I'm on my 4th bottle). It took about 2 weeks to feel anything different but I have now been able to get off of my 800mg ibuprofen 3-4 times per day and just use the corydalis. I think will be much better for my kidneys and liver than all of the NSAIDS that I've been taking for so many years. I've been so very happy with this result that I have tried other Active Herb products for some other health issues.
