Figwort Herb Extract
Also known as: Figwort Herb Extract, Ningpo Figwort, Chinese Figwort, Scrophularia ningpoensis
Overview
Figwort Herb 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 utilized for its purported anti-inflammatory, detoxifying, and immune-modulating properties. In TCM, it is commonly incorporated into multi-herb formulations to address conditions such as inflammation, skin diseases, diabetic peripheral neuropathy, and thyroid nodules. It is important to note that Figwort Herb Extract is rarely used as a standalone agent in traditional practice. Research specifically on Figwort Herb Extract as an isolated supplement is limited, with most clinical data stemming from broader Chinese herbal medicine (CHM) studies where Figwort is one component among many. The current evidence base is predominantly preclinical, with a scarcity of high-quality randomized controlled trials (RCTs) focusing exclusively on the extract. Consequently, the overall quality of evidence for its isolated effects is considered low to moderate, making it challenging to attribute specific benefits solely to Figwort Herb Extract.
Benefits
There are no high-quality randomized controlled trials (RCTs) or meta-analyses specifically evaluating the efficacy of Figwort Herb Extract as a standalone supplement. Any suggested benefits are primarily derived from its traditional use within multi-herb Chinese medicine (CHM) formulations, where its individual contribution is difficult to ascertain. Systematic reviews of CHM, which may include Figwort as a component, have suggested potential benefits in conditions such as diabetic peripheral neuropathy and benign thyroid nodules. However, these findings cannot be solely attributed to Figwort Herb Extract due to the complex nature of multi-herb formulations and the lack of isolate-specific data. Evidence for its purported anti-inflammatory and immunomodulatory effects is largely based on preclinical studies (in vitro or animal models) and traditional knowledge, rather than robust clinical trials in humans. As a result, no quantified effect sizes or clinically significant outcomes for Figwort Herb Extract alone are available from the identified literature, and its efficacy as a single agent remains unsubstantiated by strong scientific evidence.
How it works
Figwort Herb Extract contains bioactive compounds, primarily iridoid glycosides and phenylpropanoid glycosides. These compounds are believed to exert their effects by modulating cytokine production and influencing oxidative stress pathways, thereby contributing to anti-inflammatory and antioxidant activities. The proposed mechanism involves the inhibition of pro-inflammatory mediators, which could lead to a reduction in inflammation and modulation of immune responses. However, these mechanistic insights are predominantly derived from in vitro studies and animal models, and their direct applicability and significance in human physiology are not yet fully established. Furthermore, comprehensive data regarding the absorption, distribution, metabolism, and bioavailability of Figwort Herb Extract and its active components in humans are not well characterized, limiting a complete understanding of its pharmacological actions within the body.
Side effects
Specific safety data and adverse event profiles for Figwort Herb Extract as a standalone supplement are largely absent from the reviewed literature. While Chinese herbal medicines containing Figwort are generally considered safe when used under the guidance of a qualified practitioner, potential risks include general herb-drug interactions and allergic reactions, common to many botanical supplements. No documented drug interactions or contraindications specific to Figwort Herb Extract have been identified in high-quality clinical studies. However, the lack of robust, isolate-specific safety data necessitates caution. It is particularly important for pregnant or breastfeeding women, individuals with pre-existing medical conditions, and patients concurrently taking other medications to exercise extreme caution and consult a healthcare professional before considering its use. Due to the limited research, the full spectrum of potential side effects, their severity, and frequency remain largely unknown, underscoring the need for further rigorous safety evaluations.
Dosage
There are no standardized or clinically established dosing guidelines for Figwort Herb Extract when used as a single supplement. Its traditional application is almost exclusively within complex multi-herb Chinese medicine formulas, where the dosage of Figwort is part of a synergistic blend and varies widely depending on the specific formulation and the condition being addressed. Without dedicated clinical trials on Figwort Herb Extract alone, it is impossible to determine an effective dose, an optimal therapeutic range, or a maximum safe dose. The absence of such data means that minimum effective doses, timing considerations, or specific dosages for different purposes cannot be reliably recommended. Users should be aware that any suggested dosages found outside of a professionally prescribed, multi-herb TCM context are not supported by scientific evidence and may carry unknown risks.
FAQs
Is Figwort Herb Extract effective as a standalone supplement?
Current scientific evidence does not support the efficacy of Figwort Herb Extract as a standalone treatment. Its reported benefits are primarily observed within the context of multi-herb Chinese medicine formulas, making it difficult to attribute effects solely to Figwort.
Is Figwort Herb Extract safe to use?
Safety data for Figwort Herb Extract alone are insufficient. While generally considered safe within traditional multi-herb formulations under professional guidance, the lack of specific safety studies for the isolated extract means caution is advised. Consult a healthcare professional before use.
How long does it take for Figwort Herb Extract to show effects?
There are no clinical data available on the time course for effects of Figwort Herb Extract when used alone. Any observed benefits in traditional use are typically part of a prolonged regimen involving complex herbal formulas.

- https://journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0076113 – This systematic review and meta-analysis by Hao et al. (2013) investigated Chinese Herbal Medicine (CHM) for diabetic peripheral neuropathy. It included 10 RCTs, finding that CHM showed higher total efficacy than conventional treatments. However, the studies involved complex CHM formulas, not isolated Figwort, and indicated publication bias, limiting the ability to attribute effects to specific herbs.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC7909165/ – Ouyang et al. (2021) published a protocol for a systematic review on CHM for benign thyroid nodules. This review aims to evaluate the efficacy and safety of CHM, including potential effects on nodule volume and quality of life. While Figwort may be a component in some of the reviewed CHM formulas, this protocol does not provide isolate-specific data for Figwort Herb Extract.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC7331568/ – Xiong et al. (2020) conducted a systematic review on CHM for COVID-19, which included various herbs, potentially including Figwort. The review demonstrated overall benefits of CHM in managing COVID-19 symptoms. However, it did not identify any isolate-specific RCTs or meta-analyses for Figwort Herb Extract, meaning effects cannot be attributed solely to this single herb.
