Corydalis FAQ

50 grams should last you about 10 days

This herb seems to help some people a lot – some not as much. Some customers have described it as “a life saver” and some don’t re-order it.

Our Corydalis is made in high quality factories in China that export to Asia and the rest of the world. This is “hospital grade”.

No, we don’t have any special arrangements with Dr. Oz or other doctors.

Eagleherbs doesn’t usually sell single herbs (we like formulas/ groups of herbs) but sometimes we find something that can be very effective when used correctly. Yan Hu Suo (Corydalis yanhusuo) is one such herb that is effective for pain. Apparently scientists at UC Irvine have found that the roots of Yan Hu Suo (which has been used for thousands of years for pain in China) contains a compound called dehydrocorybulbine (DHCB). Who knew!? They call this type of research Neuropharmacology. This research was done on rodents so animals were harmed, so be forewarned.

In traditional Chinese Medicine Yan Hu Suo/ Cordyalis is said to “invigorate blood”. Therefore, it is contraindicated for pregnancy and in modern times is cautioned for use with blood thinners such as warfarin/ coumadin. Dr. Daniel Hsu on the Dr. Oz show mentions that it shouldn’t be used for people with irregular heart beats. Not something I had heard but not bad advice. For everyone start with a small dosages at first while paying particular attention to avoid stomach upset. This herb MAY make some feel “spacey”.

Again to quote from Dr. Oz’s website, “It should not be used by pregnant or breastfeeding women or by people with an irregular heart rhythm. It may also have some interactions with medications such as hypnotics, sedatives, cancer medications and anti-arrhythmic drugs. Always talk to your doctor before trying a new remedy or supplement.”

Note that the FDA has not evaluated any claims on Eagleherbs.com.

You may notice that we often offer Yan Hu Suo as an add-on to existing formulas for pain. We do have other formulas that direct the corydalis more specifically to parts of the body. For more specific problems you can check out other pain formulas on Eagle Herbs including Shen Tong Zhu Yu Tang and Juan Bi Tang (shoulder), Zuo Gu Shen Jing Tong Wan (Lower Trunk) as well as xue fu zhu yu tang which targets the chest and shao fu zhu yu tang which targets the lower abdomen. Some of these contain Corydalis and some use other herbs in place. Often you can “add-on” corydalis. 

100 grams should be about 20 days worth but your needs may vary. Be careful with all pain relievers that it doesn’t upset your stomach. Taking just after a meal is not a bad rule.

If you have been taking Corydalis and have some experiences to share please write us at service@eagleherbs.com .  I would love to hear how this works for you (or doesn’t). I wouldn’t publish anything that you write.


take care,
