Notopterygium incisium (Notopterygium incisium): Benefits, Dosage, Safety & Evidence

Frequently asked questions

How does Notopterygium incisium work to relieve pain?

Notopterygium incisium contains active compounds including notopterol, isoimperatorin, and various coumarins that contribute to its therapeutic effects. These compounds exert anti-inflammatory and analgesic properties through modulation of inflammatory pathways and pain signaling mechanisms. Research suggests the coumarin components may inhibit pro-inflammatory mediators, while notopterol has demonstrated analgesic activity in preclinical studies. In Traditional Chinese Medicine terms, the herb dispels wind-cold and unblocks painful obstruction, explaining its traditional use for rheumatic conditions and headache. Evidence level: C.

Is Notopterygium incisium safe to take during pregnancy?

Notopterygium incisium is contraindicated during pregnancy and should be avoided by pregnant women. Traditional Chinese Medicine considers this herb unsafe during pregnancy due to its warming, dispersing properties and potential effects on uterine activity. Additionally, individuals with Yin deficiency with heat patterns should avoid this herb according to TCM principles. Women who are pregnant or trying to conceive should consult a qualified healthcare provider before using any herbal supplements. Evidence level: Traditional.

Does Notopterygium incisium interact with any medications?

Limited clinical data exists regarding drug interactions with Notopterygium incisium. The coumarin compounds present in this herb may theoretically interact with anticoagulant and antiplatelet medications, potentially increasing bleeding risk. Patients taking warfarin, aspirin, clopidogrel, or other blood-thinning medications should exercise caution and consult a healthcare provider before use. Additionally, the herb may affect metabolism of certain drugs processed by cytochrome P450 enzymes. Always inform your healthcare provider of all herbal supplements you are taking. Evidence level: C.

What is the recommended dosage for Notopterygium incisium?

The standard adult dosage for Notopterygium incisium is 3-9 grams of dried rhizome daily, typically prepared as a decoction in Traditional Chinese Medicine. This herb is commonly combined with other TCM herbs in formulations tailored to individual patterns and conditions. Dosage may vary based on the specific condition being treated, the formulation used, and individual patient factors. Always follow the guidance of a qualified TCM practitioner or healthcare provider for personalized dosing recommendations. Evidence level: Traditional.

What is Notopterygium incisium used for in Traditional Chinese Medicine?

Notopterygium incisium is used in Traditional Chinese Medicine primarily for wind-cold conditions, including headache (particularly occipital headache) and rheumatic joint pain. The herb is valued for its ability to dispel wind-cold, relieve pain, and address dampness in the body. It is commonly prescribed for conditions characterized by joint stiffness, body aches, and headache accompanied by aversion to cold. The herb's documented anti-inflammatory and analgesic properties support these traditional applications. Evidence level: C.

Summary

Notopterygium incisium, known as 'Qianghuo', is a Chinese endemic herb used in traditional medicine for its anti-inflammatory and analgesic properties [PMID:39064831, PMID:39094757].

Background

Notopterygium incisium is a plant genus belonging to the Apiaceae (Umbelliferae) family, endemic to high-altitude regions of China such as Tibet and Gansu [PMID:39064831, PMID:28336469, PMID:28696392]. The medicinal parts are primarily the roots and rhizomes [PMID:39064831, PMID:39094757].

Traditional uses

It is traditionally used to treat headaches, colds, rheumatoid arthritis, and to disperse 'cold' and painful obstructions from wind and damp [PMID:39064831, PMID:39094757, PMID:28336469, PMID:31908072]. It is also used in Qianghuo Yufeng Decoction for liver and kidney insufficiency, mental paralysis, and dementia [PMID:39094757, PMID:31783135].

Active compounds

The herb contains over 500 compounds, including volatile oils, coumarins (such as notopterol and isoimperatorin), enynes, sesquiterpenes, flavonoids, phenolic acid esters, and polysaccharides (NIP) [PMID:39064831, PMID:40020461, PMID:41053923, PMID:37143438, PMID:28587222]. Notopterol is identified as a major constituent [PMID:2285981, PMID:36986461].

Mechanism of action

Mechanisms include inhibition of the TLR4-NF-κB pathway for neuroinflammation [PMID:39094757], inhibition of PI3K/Akt/GPX4-mediated ferroptosis in osteoarthritis [PMID:40020461], and modulation of the cAMP signaling pathway to reduce synovial inflammation [PMID:41053923]. Notopterol also acts via α7nAChR-dependent metabolic reprogramming of macrophages [PMID:41442994] and inhibits the NF-κB pathway while activating the PI3K/Akt/Nrf2 pathway in periodontal tissue [PMID:37819772]. Polysaccharides (NIP) inhibit NF-κB and JAK/STAT3 signaling [PMID:37143438].

Clinical evidence

Evidence BAxial undifferentiated spondyloarthritis

Evidence DOsteoarthritis (Animal Model)

Notopterol significantly alleviated pain, gait abnormalities, and attenuated cartilage degradation in mice [PMID:40020461]; Isoimperatorin reduced synovial inflammation in rats [PMID:41053923]

Evidence DAlzheimer's Disease (Animal Model)

Root extract (NRE) rescued cognitive deficits and attenuated amyloid-beta, tau, and neuroinflammation pathology in APP/PS1 mice [PMID:31783135, PMID:39094757]

Evidence DNeuropathic Pain (Animal Model)

Water extract reduced cold allodynia by regulating TRPA1 in mice [PMID:36587876]

Evidence DHyperuricemia-Induced Cardiac Dysfunction (Animal Model)

Notopterol improved exercise capacity and alleviated cardiac dysfunction by suppressing P2X7R and pyroptosis signals [PMID:36986461]

Evidence D

Safety & adverse effects

In a study of 102 raw pharmaceuticals, Notopterygium incisium was found to be positive in chromosomal aberration and micronucleus assays in mice [PMID:2027343].

Evidence summary

The majority of evidence is derived from in vitro studies and animal models (Level D), focusing on anti-inflammatory and neuroprotective effects. There is limited clinical data (Level B) regarding its use in complex herbal recipes for spondyloarthritis.
