    What does it do?

    From the perspective of traditional Chinese medicine (TCM), obstruction of Qi flow or blood circulation causes body discomfort 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 may potentially relieve discomfort. Yan Hu Suo (Corydalis Rhizome) is one of such Chinese herbs. Yan Hu Suo 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 discomfort. Chinese herbalists have found that Yan Hu Suo is applicable 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.

    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 discomfort in the head region. Xiang Fu promotes Qi movement, relieves Qi stagnation, and alleviates discomfort. Chuan Xiong is another famous Chinese herb that invigorates the Blood, smoothes Qi flow, and relieves discomfort. It also expels Wind.

    At a true 5:1 concentration, this product represents the most potent form of Yan Hu Suo Pian (Wan) on the market. One tablet is equal to 1 gram of raw herb.

    Please note that Guang Ci Tang® Yan Hu Suo Wan in the pill form, which has the same formulation as the tablet, is discontinued.

    Yan Hu Suo Pian tablets are made with all natural herbs that are tested for authenticity, quality, and potency. A traditional water decoction is prepared with the herbs to reproduce the time-tested action of the formula, and this water decoction is concentrated with our proprietary technology to form a potent extract that is made into easily absorbed tablets, which are remarkably effective, easy to use, and safe.

    Please note that our tablets may appear neutral in finishing and a little brittle. You may observe a tiny bit of fine powder at the bottom of your bottle and occasionally one or a couple of broken tablets after transportation. This is because unlike other manufacturers, our tablets are not coated as part of our effort to minimize the use of excipients and to make them as pure as possible. These tablets can also be easily dissolved in hot water to serve as tea.

    Corydalis Relaxe™ (Yan Hu Suo Zhi Tong Pian) is rated 4.4 out of 5 by 29.
    Rated 5 out of 5 by from 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.

    Rated 5 out of 5 by from Corydalis is working for me. I first heard about Corydalis on the Dr. Oz show. I purchased the granules and did not like the taste, so I then purchased these tablets. Now I take the granules mixed with my morning coffee and the tablets three, with the evening meal. My neuropathy has disappeared. I tried an experiment where I stopped taking the Corydalis for a couple of days and the pain came back on the second day and I resumed taking the Corydalis. I am very happy with the pain relief and no side effects. I have recommended the tablets to others who have neuropathy and given them 20-30 tablets to try and so far three people have ordered the tablets on their own.

    Rated 5 out of 5 by from 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.

    Rated 5 out of 5 by from 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.

    Rated 5 out of 5 by from Works as Stated This worked as the word out there is telling everyone to purchase. I took the exact dosage once for bad Arthritis and slight headache, and it worked faster than any of the other pain products I've taken over the years, with no stomach upset or side effects. Amazing that I only had to take it once that day. I say to get this product for any pains you have and wait for it to work better than anything else you've ever tried.

    Rated 5 out of 5 by from Working! 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.

    Rated 4 out of 5 by from Took away dental pain I came back from the dentist after some strong work on a back molar. I took 5 of these tablets when the novacaine was wearing off. I felt a mild decrease in the pain. After a couple hours, I took 5 more and the pain was disappearing. I took 5 more a few hours later, and the pain was totally gone. It never came back. I was saved from taking NSAIDs!

    Rated 5 out of 5 by from It really does relax I have been taking this for three weeks now and it has made my pain much less severe. I have found that I must take the five (5) tablets three (3) times a day as directed. Overall, I will buy this product again. Price is great and they provide excellent service!
