Figwort Extract
Also known as: Figwort Extract, Ningpo Figwort, Chinese Figwort, Figwort, Scrophularia ningpoensis
Overview
Figwort Extract is derived from the root of *Scrophularia ningpoensis*, a plant with a long history of use in Traditional Chinese Medicine (TCM). It is primarily valued for its purported anti-inflammatory, immunomodulatory, and detoxifying properties. The extract contains various bioactive compounds, including iridoids, phenylpropanoids, and flavonoids, which are believed to contribute to its therapeutic effects. While preclinical research (in vitro and in vivo studies) suggests promising biological activities, high-quality randomized controlled trials (RCTs) specifically on Figwort Extract as a standalone supplement are limited. Most existing clinical evidence is indirect, often stemming from studies on complex Chinese herbal formulations that include Figwort among other ingredients, making it challenging to isolate the specific effects of Figwort Extract.
Benefits
Figwort Extract demonstrates several potential benefits, primarily supported by preclinical research: * **Anti-inflammatory effects:** Multiple studies indicate that Figwort Extract can inhibit inflammatory mediators such as interleukins (IL-1β, IL-4, IL-6) and tumor necrosis factor-alpha (TNF-α) in cell and animal models. This suggests its potential utility in managing inflammatory conditions. The evidence for this benefit is strong in preclinical settings but lacks robust human clinical trials. * **Immunomodulatory effects:** The extract has been shown to reduce nitric oxide production and suppress inducible nitric oxide synthase (iNOS) activity, indicating its ability to modulate immune responses. This effect is well-documented in laboratory and animal studies. * **Potential in diabetic peripheral neuropathy (DPN):** Systematic reviews of Chinese herbal medicines, which may include Figwort as part of multi-herb formulas, have shown some efficacy in improving DPN symptoms compared to certain controls. However, it is crucial to note that Figwort-specific data are not isolated in these reviews, and the evidence is indirect, with concerns regarding heterogeneity and publication bias. There is no high-quality clinical evidence to support Figwort Extract as a standalone treatment for DPN.
How it works
The primary mechanism of action for Figwort Extract's anti-inflammatory properties involves the inhibition of NF-κB signaling pathways. This process reduces the phosphorylation of inhibitor κBα (p-IκBα), thereby decreasing the production of pro-inflammatory cytokines. Additionally, the extract suppresses iNOS, which in turn reduces nitric oxide, a key mediator of inflammation and oxidative stress. The various bioactive compounds present in Figwort Extract are believed to interact with immune cells, modulating cytokine release and influencing inflammatory cascades. However, detailed pharmacokinetic data, including absorption and bioavailability in humans, are currently limited, making a comprehensive understanding of its systemic effects challenging.
Side effects
The overall safety profile of Figwort Extract is not well-documented through rigorous, high-quality clinical trials. While traditional use suggests a low toxicity at customary doses, there is a lack of comprehensive data on common or serious adverse effects in modern scientific literature. Specific drug interactions and contraindications have not been thoroughly studied; therefore, caution is advised when combining Figwort Extract with immunomodulatory or anti-inflammatory medications due to the potential for additive effects. Furthermore, safety data for special populations, such as pregnant or lactating individuals and children, are absent. Users should exercise prudence and consult with a healthcare professional before use, especially if they have pre-existing medical conditions or are taking other medications.
Dosage
There is no standardized dosing established for Figwort Extract based on high-quality clinical trials. Traditional Chinese Medicine typically utilizes root decoctions in variable amounts, which do not translate directly to standardized extract dosages. Without robust, RCT-based dosing guidelines, clinical use should ideally follow traditional formulations or be guided by a qualified Traditional Chinese Medicine practitioner. Factors such as bioavailability and cofactor requirements for optimal efficacy remain uncharacterized. Due to the lack of scientific consensus on effective and safe dosages, self-dosing is not recommended, and any use should be approached with caution and professional guidance.
FAQs
Is Figwort Extract effective as a standalone supplement?
Current scientific evidence is insufficient to confirm the efficacy of Figwort Extract as a standalone supplement. Most clinical data come from multi-herb formulas, making it difficult to attribute benefits solely to Figwort.
Is Figwort Extract safe?
While traditionally considered safe, Figwort Extract lacks rigorous clinical safety data from modern trials. Caution is advised, especially regarding potential drug interactions and use in special populations.
How quickly do benefits appear?
Due to the absence of high-quality clinical trials, the onset of potential benefits from Figwort Extract is currently unknown. Individual responses may vary.
Can Figwort Extract replace conventional anti-inflammatory drugs?
No, there is no evidence to support Figwort Extract as a replacement for conventional anti-inflammatory drugs. It may be considered as a complementary approach at best, under professional guidance.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC7331568/ – This review summarizes the phytochemistry and pharmacology of *Scrophularia ningpoensis*. It highlights that ethanol and methanol extracts exhibit anti-inflammatory effects by suppressing IL-4, TNF-α, iNOS, and NF-κB pathways in both in vitro and in vivo models. The study is comprehensive but primarily focuses on preclinical data, lacking clinical RCTs.
- https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0076113 – This systematic review and meta-analysis evaluated Chinese herbal medicine (CHM) for diabetic peripheral neuropathy (DPN). It found that CHM monotherapy showed better efficacy than mecobalamin and inositol. While Figwort may be part of some CHM formulas, its specific contribution was not isolated, and the review noted heterogeneity and potential publication bias.
