Dear Pain Matters blog readers,
Is traditional chinese medicine (TCM) a treasure box that needs to be opened more fully??
In other words, should more research be done to scientifically explore the hidden treasures of TCM? If we did this, would we find additional effective pain treatment options not yet offered by conventional medicine?
Consider this ancient, nonaddictive, Chinese herbal remedy for chronic nerve pain that may, at times, offer longer lasting pain relief than opiates:
The roots of a flowering poppy plant called Corydalis yanhusuo (C. yanhusuo; Corydalis) has been used for centuries as a Chinese remedy for chronic pain. Corydalis is grown in China, Japan and Siberia. The underground tubers from the Corydalis plant must be harvested, dried, ground, and boiled in hot vinegar before they can be used as a remedy for pain including headaches, back pain, menstrual cramps, chest pain and abdominal pain.

In collaboration with Chinese scientists, University of California researchers have recently identified and isolated a key pain-relieving compound called dehydrocorybulbine (DHCB) in the roots of Corydalis. Specifically, basic research showed that DHCB (extracted from the Corydalis tubers) reduced acute pain, inflammatory pain as well as injury-induced nerve pain. The compound, DHCB, blocks dopamine D2 receptors.
More importantly, the DHCB does not interact with the morphine receptor. As such, the effectiveness of DHCB will not weaken over time, nor will tolerance, addiction and drug dependence become issues (as often occurs with conventional opiate medicine including codeine and morphine).
Researchers felt that DHCB could offer some relief for low-level chronic pain without the risk of addiction or tolerance following repeated use (Zhang et al, 2014; Ingram, 2014).
Patient experiences with Corydalis yanhusuo extracts:
While not scientifically verifiable, the following (partially copied) user comments are interesting to read:
User Reviews & Rating – CORYDALIS
Quoting comments from a disappointed pain patient:
“I took my first capsule this morning and have felt tired, dragged out, strangely a little depressed and above all light-headed–dizzy enough to stumble and fall. If anything, my painful back, hips and knees hurt more today. Obviously I won’t take it again.“
Quoting positive comments from people with chronic pain who use Corydalis:
“…both knees replaced at the same time, and also suffer from frequent headaches. I began using this product after my surgery and it has provided me with great relief! ….easier on my GI system….Love Corydalis! Been a lifesaver for me!“
“I have been taking 1-2 capsules a day. It helps my joint pain considerably which I’ve had for 20 years….”
“I have had severe knee pain for several years due to old sports injuries and have began using the Cordyalis 10:1 pills recently. The first day my pain was so subtle that I hardly noticed it at all. Stairs were a nightmare for me, but they are much, much easier to handle. I know that nothing can completely remove the pain I suffer from, but this is positively changing my quality of life!!“
“I have degenerative disc disease and get spinal headaches from intermittent neck pain. I was instructed by a Taiwanese doctor to take 20g boiled in water from 500cc down to 250cc (about 25 minutes on electric stove med-hi), straining out and discarding the root at the end. I found 20g was too much (I experienced worse spasms), tried 5g, and ended up using 10g per serving, up to twice a day. I found that taking it daily was less effective than taking as needed (was hoping to keep the pain away by taking daily.) When I first used it, it made me “high” like cough syrup. After a few servings, I no longer feel that. It’s probably the most effective thing I’ve taken for the pain (I will not take opioids, which tend to make me sick anyway.) …. The tea from root tastes horrible….”
“I have had constant shoulder and neck pain for 2 yrs which also cause headaches and migraines. Muscle relaxers and fiorcet are my daily regimine but still constant pain that made me so tired and energy draining. Since using corydalis i have energy and no shoulder pain.“
“Has eased my intractable nerve pain.”
“Female, 66 – for sciatica. I take the powder: premixed, in hot water – drink it fast so as to obscure the taste. Worked in 30 min. the first time taken. I take it 1/2 hr before eating dinner. I’ve learned to put Stevia in it – helps with the taste.”
“This stuff works, however, I have only taken it in the powdered form. It tastes terrible … Its hard to figure out dosages. I take two teaspoons per day on most days to augment my pain medication, hydrocodone. It dramatically extends the time the hydrocodone works and seems to add some additional relief. I am concerned about possible harmful effects and standardization of strengths of the herb……”
Based on above, is it possible that the effectiveness of certain conventional pain medication (in this case, hydrocodone) may be increased, and/or prolonged, through the use of Corydalis? Further research is warranted.]
“I have experience chronic low back pain for about 2 years. The pain is 24/7 and worsens with inactivity or excessive physical fitness. I purchased capsules. The serving size is 8 capsules and I only took 3 and felt amazing relief. I lifted weights today for my legs and shoulders then did 15 minutes of interval sprints and my back feels PHENOMENAL! For $15.99 it is worth the try!….”
“I have a bulging disk and pain 24/7, at times it feels like to torture. Corydalis has helped the pain a little so my pain level is 4 instead of 7 or 8.“
“I have had fibromyalgia for 25 years and now suffer spinal stenosis after car wreck 10 years ago. I have found acupuncture and this herb to help the pain and neurological problems.….”
A huge word of caution:
While DHCB is currently not available, TCM practitioners can offer Chinese herbal remedies/extracts that specifically include Corydalis yanhusuo extracts or roots/tubers (as they have already done for many centuries). Corydalis extracts are also available in Chinese specialist stores and on-line.
However, in Dr Civelli’s words, “DHCB is present in low quantities, but it’s there” (Chia, 2014).
Thus, traditional Chinese remedies that include Corydalis yanhusuo extracts or tubers are certainly worth trying (after discussing with your GP first).
Please discuss with your GP before deciding to undergo any TCM treatments and/or other alternative/complementary medical treatments (as well as post-TCM treatment, if necessary).
Increased funding and research into TCM including ancient Chinese herbal remedies for pain are warranted.
In particular, we need to expand research into Corydalis, and its key pain-relieving ingredient, DHCB (as well as research into other effective pain-alleviating remedies offered by TCM).
After all, the best approach is a global and unified approach to the global challenge of chronic pain.
