Corydalis, also known as Yan Hu Suo, is a centuries-old remedy from Traditional Chinese Medicine (TCM) that has been used for:

    • Pain relief, including acute, menstrual, inflammatory, and neuropathic 
    • Fibromyalgia 
    • Mild depression 
    • Mental and emotional disorders
    • Nerve damage
    • Tremors
    • Insomnia
    • Intestinal spasms
    • And other ailments

Corydalis is a tall, thin herb native to the Zhejiang province of China. The plant consists of a thin, green stem with green leaves and delicate thin flower bunches. The rhizome is used for medicinal purposes.

In TCM, Corydalis is believed to invigorate the blood and facilitate the movement of qi throughout the body.

Corydalis is an ancient remedy from TCM that has been used for pain relief. Corydalis has also been used to treat mild depression, mental and emotional disorders, severe nerve damage, fibromyalgia and limb tremors. Additionally, it has been used as a mild sedative and to lessen intestinal spasms. TCM practitioners have considered it to be the second most effective pain reliever after opium and without the opiate side-effects. Scientific research has found the active ingredients in Corydalis to operate as a mild sedative and effective for relieving insomnia as well as an effective analgesic for acute, inflammatory, menstrual and neuropathic pain. Further, it can cross the blood-brain barrier and is not found to be addictive.

Corydalis is generally considered to be safe for healthy adults but considered to be dangerous for pregnancy as it is a blood activator, and not enough is known about it to consider it safe for breastfeeding. Corydalis should not be used by pregnant or breastfeeding women or by people with an irregular heart rhythm as it has been found to have cardiovascular actions. There are no known drug interactions documented to date, but Corydalis may have some interactions with medications such as hypnotics, sedatives, cancer medications and anti-arrhythmic drugs.

Side-effects are rarely noted and not well known, but taking Corydalis could lead to vertigo, fatigue or nausea. Taking too much may cause spasms and muscle tremors. In addition, there have been reports of subjects experiencing THP toxicity, which could lead to hepatitis.

Quality is important. Many Corydalis products on the market today come from various countries, like China, where the quality of ingredients or manufacturing guidelines vary greatly. You can trust Dr. Tennant’s quality. Dr. Tennant uses only the purest and best quality ingredients source-able, and all Tennant Products are made 100% in the USA in a GMP (Good Manufacturing Practice) lab.
