Summary
Devil's Club (Oplopanax horridus) is a medicinal plant native to North America, particularly the Pacific Northwest, used traditionally for various ailments and currently studied for its anticancer and anti-inflammatory properties [PMID:30302120, PMID:20723598].
Background
Oplopanax horridus is a botanical native to North America and is the only species of the genus Oplopanax distributed in this region [PMID:22101399]. It is considered a significant spiritual and medicinal plant for indigenous peoples of Alaska and the Pacific Northwest [PMID:20723598, PMID:25340187].
Traditional uses
Traditionally used by indigenous peoples for internal and external infections, arthritis, respiratory ailments, digestive tract ailments, broken bones, fever, headaches, cancer, colds, cough, and diabetes [PMID:20723598, PMID:15154981, PMID:16814500].
Active compounds
Identified compounds include polyynes (such as falcarindiol and oplopantriol A and B), polyenes (including (S,E)-nerolidol), sesquiterpenes, monoterpenoids, phenylpropanoids, phenolic acids, lignans, glycosides, and lupane-type triterpenoid saponins [PMID:22101399, PMID:32496571, PMID:20734931, PMID:25282894, PMID:20638214].
Mechanism of action
Polyacetylenes have been shown to activate PPARγ, a transcription factor involved in metabolic regulation [PMID:32129622]. In cancer cells, compounds modulate genes related to pro-apoptosis, anti-apoptosis, cell cycle, stress, and death receptors [PMID:30661403]. Leaf extracts reduce LPS-induced nitric oxide (NO), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) production by decreasing iNOS expression [PMID:30263531].
Clinical evidence
Evidence DCancer (Various types)
In vitro studies demonstrate antiproliferation activity against breast, colon, pancreatic, ovarian, and leukemia cell lines [PMID:20723598, PMID:24215675, PMID:19835944, PMID:26221768, PMID:25340187, PMID:20332432]. Oplopantriol A showed dose-related suppression of tumor growth in xenograft colon cancer mouse models [PMID:25045937].
Evidence DDiabetes Mellitus
A pilot study monitoring blood glucose levels in insulin-dependent and non-insulin-dependent diabetic patients showed no hypoglycemic effect of devil's club tea [PMID:21249104].
Evidence DInflammation
Leaf extracts demonstrated anti-inflammatory effects by reducing LPS-induced NO, TNF-α, and IL-6 in murine macrophages [PMID:30263531].
Evidence DMycobacterial Infections
Isolated polyynes exhibited significant antibacterial and antimycobacterial activity, including the ability to kill Mycobacterium tuberculosis and isoniazid-resistant Mycobacterium avium [PMID:9392889].
Drug interactions
In vitro studies suggest that Devil's club extract may enhance the antiproliferation activity of chemotherapeutic agents such as cisplatin (CDDP) and gemcitabine (GEM) [PMID:24215675, PMID:26221768].
Evidence summary
The current evidence is primarily based on in vitro cell studies, animal models (xenografts), and limited pilot observations. There is a lack of high-level clinical trial data (RCTs) or systematic reviews regarding human efficacy and safety.
