Polygonum Aviculare Extract
Also known as: Polygonum aviculare L., Knotweed, Bird's Knotweed, Polygonum, Polygonum aviculare
Overview
Polygonum aviculare L., commonly known as knotweed, is a plant species found worldwide and traditionally used for its medicinal properties. It is primarily recognized for its antioxidant and anti-inflammatory effects. Research suggests potential benefits in reducing inflammation, improving cardiovascular health, and possibly aiding in anti-cancer therapies. The plant contains various bioactive compounds that contribute to its therapeutic effects. It is available in various forms, including extracts and herbal preparations. While studies have explored its biological activities, more rigorous clinical trials are needed to confirm its efficacy and safety in humans. Its historical use and promising preliminary research make it a subject of ongoing scientific interest.
Benefits
Polygonum aviculare L. extract exhibits antioxidant and anti-inflammatory properties, potentially reducing oxidative stress and inflammation. Studies suggest it may have anti-atherosclerotic effects by modulating the MAPK pathway, indicating potential cardiovascular benefits. Animal studies indicate a reduction in fatigue by inhibiting neuroinflammation. While these findings are promising, further research is needed to quantify effect sizes and establish clinical significance in human populations. Its anti-inflammatory properties may be particularly beneficial for individuals with chronic inflammatory conditions, but specific data on population-specific benefits is limited. More quantitative studies are necessary to confirm these benefits.
How it works
Polygonum aviculare L. extract exerts its effects primarily through antioxidant and anti-inflammatory mechanisms. It interacts with biological pathways such as the MAPK pathway, influencing cardiovascular health by reducing atherosclerosis. The extract may also have neuroprotective effects by inhibiting neuroinflammation. It modulates transcription factors and signaling pathways involved in inflammation and oxidative stress. However, detailed information on the absorption, bioavailability, and specific molecular targets of Polygonum aviculare L. extract remains limited, requiring further investigation to fully elucidate its mechanisms of action.
Side effects
The safety profile of Polygonum aviculare L. is not comprehensively documented. Common side effects are not well-established due to limited human studies. Uncommon and rare side effects are largely unknown. Potential drug interactions with medications affecting inflammation or cardiovascular health are speculative without specific studies. While no contraindications are definitively established, caution is advised during pregnancy or breastfeeding due to a lack of safety data. Individuals with allergies to plants in the Polygonaceae family should exercise caution. Overall, more research is needed to fully assess the safety and potential adverse effects of Polygonum aviculare L.
Dosage
Due to limited research, a minimum effective dose for Polygonum aviculare L. has not been established. Optimal dosage ranges vary based on the preparation and intended use. A maximum safe dose is not defined. There are no specific timing recommendations for its use. Extracts are commonly used, but no particular form has been proven superior. Information on absorption factors and required cofactors is currently unknown. Given the lack of comprehensive data, it is essential to consult with a healthcare provider before using Polygonum aviculare L. to determine an appropriate and safe dosage.

Research Sources
- https://pubmed.ncbi.nlm.nih.gov/34575493/ – A study evaluating the effects of Polygonum aviculare L. extract on doxorubicin-induced toxicity in endothelial cells found that it exerted antioxidant and anti-inflammatory activities, though to a lesser extent compared to quercetin. The research suggests potential protective effects against doxorubicin-induced damage through antioxidant mechanisms. This indicates a possible adjunctive role in mitigating chemotherapy-related toxicity.
- https://journals.sagepub.com/doi/pdf/10.1177/2156587215600873 – This study investigates the anti-atherosclerotic effects of Polygonum aviculare L. ethanol extract in ApoE knock-out mice. The research demonstrates that the extract has anti-atherosclerotic effects mediated via the MAPK pathway. These findings suggest a potential therapeutic role in managing atherosclerosis through modulation of inflammatory signaling pathways.
- https://daneshyari.com/en/article/8518433 – This study in restraint-stressed mice showed that Polygonum aviculare L. extract reduces fatigue by inhibiting neuroinflammation. The research indicates that the extract has potential in alleviating fatigue symptoms by targeting inflammatory processes in the brain. This suggests a possible application in managing stress-related fatigue.
