About Corydalis for Pain

The root of the Corydalis plant is known as YAN HU SUO. It is also known as Engosaku in Japan, and Yonhosaek in Korean. YAN HU SUO is classified as a Blood Vitalizer in Traditional Chinese Medicine. 

Most Blood Vitalizer (Movers) are used used for pain relief, and most, including corydalis, are contraindicated (forbidden) during pregnancy and nursing. 

Many practitioners of Traditional Chinese Medicine (TCM) consider YAN HU SUO to be the second most effective pain reliever, opium being the first. More exactly, its properties and uses in TCM include 'invigorating the blood' and 'invigorating the Qi', making it useful for a wide variety of painful conditions.

Pharmaceutical companies have recently taken an interest in one chemical constituent of this herb, dehydrocorybulbine (DHCB) as potentially useful in creating new, non opioid, drugs for pain relief. It should be pointed out that there are other active alkaloids in this herb including corydaline, dl-tetrahydropalmatine, protopine, corybulbine, β-homochelidonine, and others.

Lately, this herb has been recommended by the TV personality Dr. Oz, for treatment of fibromyalgia. What Dr. Oz did not say is that this herb is rarely used alone and is almost always used together with other herbs in formulas. For example, it is combined with herbs such as RU XIANG (frankincense) and MO YAO (myrrh) for pain from injuries, with ROU GUI (cinnamon bark) for menstrual pain, with XIAO HUI XIANG (fennel) for hernia pain, and with CHUAN XIONG (Liguisticum) for headache. Its pain relieving properties can be enhanced by frying the whole herb in vinegar.

Research has shown that the herb has a light hypnotic and sedative effect in many animals and reduces menstrual flow and pain in humans. In an other experiment, ingestion by humans produced no gastric side effects.

Corydalis is available on this site in capsules, as granules which are simply stirred into liquid and taken three times daily, or as a whole herb which is boiled and taken three times a day. Potent tinctures can be made by immersing the whole herb in vodka (or other alcoholic beverage) for 2 weeks. Though whole herbs are considered most powerful, novice users are advised to begin with capsules or herb granules.
