Typha Angustifolia Pollen Extract
Also known as: Narrowleaf cattail pollen extract, Lesser bulrush pollen extract, Typha angustifolia L. pollen extract, Typha angustifolia pollen extract
Overview
Typha angustifolia pollen extract is derived from the pollen of the narrowleaf cattail plant, a traditional medicinal plant used in Chinese medicine for various ailments including trauma, menstrual irregularities, bleeding, and inflammation. This extract is rich in bioactive flavonoids and phenolic compounds, which contribute to its observed antioxidant, antiviral, analgesic, and anti-inflammatory properties. While preclinical studies (in vitro and animal models) show promising results for its antiviral and analgesic effects, clinical evidence, particularly from randomized controlled trials, is limited. Research on its efficacy for menopausal symptoms, often conducted with general purified pollen extracts rather than specifically T. angustifolia, has yielded inconclusive results, suggesting a potential placebo effect. The extract is generally considered safe with no major adverse effects reported.
Benefits
Typha angustifolia pollen extract exhibits several potential benefits, primarily supported by preclinical research. It demonstrates significant **antiviral activity** in vitro, particularly with water extracts rich in flavonoids like quercetin derivatives, which possess antioxidant and electron-shuttling properties that may inhibit viral replication pathways. Animal studies have shown notable **analgesic and anti-inflammatory effects**, with specific flavonoids (e.g., isorhamnetin-3-O-neohesperidin, typhaneoside) reducing chemically induced pain in mice by over 50%, sometimes outperforming conventional pain relievers like diclofenac sodium. Additionally, the extract provides **antioxidant activity** due to its high phenolic and flavonoid content, which helps scavenge free radicals and reduce oxidative stress, potentially supporting general health. For **menopausal symptom relief**, a meta-analysis of purified pollen extracts (not exclusively T. angustifolia) indicated improvements in uncontrolled studies, but no statistically significant benefit was found in randomized controlled trials, suggesting that observed benefits might be due to placebo effects rather than direct pharmacological action.
How it works
The mechanism of action for Typha angustifolia pollen extract is primarily attributed to its rich content of flavonoids and phenolic compounds. Its **antiviral potential** is linked to electron-shuttling flavonoids that can generate bioenergy and interfere with viral replication pathways. The **analgesic effects** are believed to stem from flavonoid-mediated modulation of pain perception and inflammatory pathways, leading to a reduction in nociceptive signaling and inflammatory mediators. The extract's **antioxidant activity** is a direct result of its high phenolic and flavonoid content, which effectively scavenges free radicals and mitigates oxidative stress within the body. While these mechanisms are understood at a preclinical level, the specific bioavailability and metabolic pathways of its active compounds in humans are not yet well characterized, though flavonoids generally exhibit moderate absorption and undergo hepatic metabolism.
Side effects
Typha angustifolia pollen extract appears to have a favorable safety profile, with no major adverse effects reported in the limited clinical or preclinical studies available. Side effects are considered rare and are not well-documented in the existing literature. There are currently no significant drug interactions or contraindications that have been identified or documented. While this suggests a high degree of safety, it is important to note that comprehensive human safety data, especially regarding long-term use and specific populations (e.g., pregnant or breastfeeding individuals, those with allergies to pollen), are limited. Users should exercise caution and consult a healthcare professional, particularly if they have known allergies to pollen or are taking other medications, as the full spectrum of potential interactions and adverse reactions has not been thoroughly investigated in human trials.
Dosage
Specific dosing guidelines for Typha angustifolia pollen extract in humans are not yet established due to the limited number of clinical trials. Research on purified pollen extracts for menopausal symptoms, which may or may not have included T. angustifolia, typically involved treatment durations of approximately three months, but did not specify standardized dosages. Animal studies demonstrating analgesic effects used doses extrapolated to mice models, making it difficult to define human equivalent doses. The optimal extraction method also influences the extract's potency; water extracts have shown higher flavonoid content and antioxidant activity compared to ethanol extracts. Without clear clinical data, it is not possible to recommend a specific dosage range, timing considerations, or upper safety limits for human consumption. Any use should be approached with caution and preferably under the guidance of a healthcare professional.
FAQs
Is Typha angustifolia pollen extract effective for menopausal symptoms?
Current controlled clinical evidence does not strongly support its efficacy for menopausal symptoms beyond a potential placebo effect, according to a meta-analysis of purified pollen extracts.
Is it safe to use?
Yes, no major adverse effects have been reported in available studies, indicating a generally safe profile. However, long-term human safety data are still lacking.
Can it be used as an antiviral?
Preclinical data suggest potential antiviral properties in vitro, but there are no clinical trials confirming its efficacy as an antiviral in humans.
How quickly do effects appear?
In animal studies, analgesic effects were observed acutely. For menopausal symptoms, studies typically assessed outcomes after approximately three months of use.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC11511223/ – This in vitro and phytochemical analysis study found that water extracts of Typha angustifolia pollen exhibited high antioxidant activity and contained electron-shuttling flavonoids with potential antiviral properties. It provides mechanistic insights but lacks clinical data.
- https://pubmed.ncbi.nlm.nih.gov/38194609/ – This meta-analysis, including one RCT and four observational studies, investigated purified pollen extracts for vasomotor symptoms. It found improvements in uncontrolled studies but no significant effect in randomized controlled trials, suggesting a possible placebo effect and highlighting the need for more robust RCTs.
- https://www.frontiersin.org/journals/pharmacology/articles/10.3389/fphar.2025.1557136/full – This animal study demonstrated that Typha angustifolia extract produced dose-dependent analgesic effects in mice, sometimes surpassing diclofenac. It also identified active flavonoids responsible for these effects, providing strong preclinical evidence for its pain-relieving properties.
