## Overview

Euphorbia hirta contains flavonoids and triterpenoids that demonstrate [anti-inflammatory](/ingredients/condition/inflammation) activity through inhibition of nitric oxide production in immune cells. The plant's anxiolytic effects appear to work via GABA_A receptor modulation in the central nervous system.

## Health Benefits

• [Anti-inflammatory](/ingredients/condition/inflammation) effects demonstrated in vitro using 200 µg/mL extract in RAW264.7 cells, reducing nitric oxide production (preliminary evidence)
• Anxiolytic properties shown in rat models at 200 mg/kg oral dose for 7 days, working via GABA_A receptor modulation (animal evidence only)
• Potential anticancer activity against HL-60 leukemia cells at 100-200 µg/mL concentrations in vitro (preliminary evidence)
• Traditional respiratory support for asthma, bronchitis, and cough based on centuries of ethnomedicinal use (traditional evidence only)
• [Antioxidant](/ingredients/condition/antioxidant) effects through flavonoid content activating Nrf2 pathways, demonstrated in cell studies (preliminary evidence)

## Mechanism of Action

Euphorbia hirta's flavonoid compounds inhibit nitric oxide synthase in activated macrophages, reducing inflammatory nitric oxide production at concentrations of 200 µg/mL. The plant's anxiolytic activity involves modulation of GABA_A receptors in the central nervous system, enhancing inhibitory neurotransmission. Triterpenoid compounds may contribute to both [anti-inflammatory](/ingredients/condition/inflammation) and neurological effects through multiple signaling pathways.

## Clinical Summary

[Anti-inflammatory](/ingredients/condition/inflammation) effects have been demonstrated only in vitro using RAW264.7 macrophage cells, showing reduced nitric oxide production with 200 µg/mL extract treatment. Anxiolytic properties were observed in animal studies using rat models at 200 mg/kg oral doses administered for 7 days. No human clinical trials have been conducted to validate these preliminary findings. The evidence remains limited to laboratory and animal studies, requiring human research for clinical relevance.

## Nutritional Profile

Euphorbia hirta is not consumed as a conventional food, so standard macronutrient profiling (carbohydrates, fats, protein per 100 g edible portion) is limited. It is primarily valued for its bioactive phytochemical content rather than caloric or macronutrient contribution. Key compounds identified include: **Flavonoids:** Quercetin (approximately 0.8–1.5 mg/g dry weight), quercitrin, myricitrin, and rutin, which contribute to its [antioxidant](/ingredients/condition/antioxidant) and [anti-inflammatory](/ingredients/condition/inflammation) activity. **Polyphenols:** Total phenolic content reported in the range of 45–85 mg gallic acid equivalents (GAE)/g dry extract, depending on solvent and plant part. **Tannins:** Ellagic acid and gallic acid derivatives present at approximately 10–25 mg/g dry extract; these contribute astringent and [antimicrobial](/ingredients/condition/immune-support) properties but may reduce bioavailability of dietary iron and proteins if co-consumed. **Terpenoids:** Euphol, taraxerol, and β-amyrin identified in stem latex and whole-plant extracts; concentrations vary but are typically in the low mg/g range in crude extracts. **Alkaloids:** Trace amounts detected in whole-plant methanolic extracts. **Sterols:** β-sitosterol and campesterol present in small quantities (approximately 0.2–0.5 mg/g dry weight). **Minerals (from whole dried herb):** Potassium (~12–18 mg/g), calcium (~8–15 mg/g), magnesium (~3–6 mg/g), iron (~0.3–0.8 mg/g), and zinc (~0.03–0.08 mg/g) have been reported in elemental analyses of dried aerial parts; however, bioavailability is likely reduced by tannin content. **Vitamins:** Ascorbic acid (vitamin C) has been detected in fresh leaf tissue at approximately 30–60 mg/100 g fresh weight, though this degrades significantly upon drying or boiling. **Fiber:** Crude fiber in dried whole herb is estimated at 15–22% by weight, typical of leafy herbaceous plants. **Fatty acids:** Linoleic acid and oleic acid are the predominant fatty acids in seed oil fractions, though total lipid content of the whole plant is low (~2–4% dry weight). **Bioavailability notes:** Most pharmacological studies use concentrated methanolic or ethanolic extracts; bioavailability of key flavonoids like quercetin from crude decoctions (traditional preparation) is expected to be low (typically <5–10% oral absorption in humans). The presence of tannins may further chelate minerals and reduce polyphenol absorption. No human pharmacokinetic studies specific to Euphorbia hirta preparations are currently available.

## Dosage & Preparation

Animal studies used 200 mg/kg oral daily for anxiolytic effects. Toxicity studies in rats showed safety up to 5000 mg/kg single dose and 1000 mg/kg daily for 90 days. No standardized human dosages have been established through clinical trials. Consult a healthcare provider before starting any new supplement.

## Safety & Drug Interactions

Safety data for Euphorbia hirta is extremely limited with no established human dosing guidelines or toxicity profiles. As a member of the Euphorbia family, it may contain latex compounds that could cause skin irritation or allergic reactions in sensitive individuals. Potential interactions with GABA-ergic medications like benzodiazepines or anticonvulsants are theoretically possible given its GABA_A receptor activity. Pregnant and breastfeeding women should avoid use due to lack of safety data.

## Scientific Research

Clinical evidence for Euphorbia hirta is extremely limited, with only one systematic review (PMID: 29849664) identifying a single human trial among eight studies on antidengue activity, though trial details were not specified. The majority of research consists of animal studies (anxiolytic effects in rats at 200 mg/kg) and in vitro investigations demonstrating [anti-inflammatory](/ingredients/condition/inflammation) and cytotoxic properties in various cell lines.

## Historical & Cultural Context

Euphorbia hirta has been used for centuries in Ayurvedic, African, and Asian folk medicine systems to treat respiratory ailments, female disorders, and worm infestations in children. Traditional applications also include galactogenic, anti-anaphylactic, [antimicrobial](/ingredients/condition/immune-support), and antimalarial purposes across tropical regions.

## Frequently Asked Questions

### What is the effective dose of Euphorbia hirta for anxiety?

Animal studies used 200 mg/kg oral doses for 7 days to demonstrate anxiolytic effects. However, no human dosing guidelines exist, and this animal dose cannot be directly translated to human use without clinical trials.

### Does Euphorbia hirta interact with anti-anxiety medications?

Theoretical interactions may occur with GABA-ergic drugs like benzodiazepines due to Euphorbia hirta's GABA_A receptor modulation. No specific drug interaction studies have been conducted, so caution is advised when combining with psychiatric medications.

### What compounds in Euphorbia hirta cause anti-inflammatory effects?

Flavonoid compounds are primarily responsible for anti-inflammatory activity through nitric oxide synthase inhibition. Triterpenoids may also contribute to reducing inflammation, though specific compound identification requires further research.

### Is Euphorbia hirta safe for long-term use?

Long-term safety has not been established in humans, with only 7-day animal studies available. The lack of toxicity data and potential for latex-related allergic reactions make long-term use inadvisable without medical supervision.

### How does Euphorbia hirta compare to prescription anti-anxiety drugs?

Euphorbia hirta has only shown anxiolytic effects in animal models, while prescription medications have extensive human clinical data. The plant's GABA_A receptor activity suggests similar mechanisms to benzodiazepines, but efficacy and safety comparisons cannot be made without human trials.

### Is Euphorbia hirta safe during pregnancy and breastfeeding?

There is insufficient clinical data on the safety of Euphorbia hirta during pregnancy and breastfeeding, and it should be avoided during these periods as a precaution. Traditional use does not guarantee safety in vulnerable populations. Pregnant and nursing women should consult a healthcare provider before considering this herb.

### What is the quality of scientific evidence supporting Euphorbia hirta's health claims?

Current evidence for Euphorbia hirta is limited to preliminary in vitro studies and animal models, with no published human clinical trials available. The anti-inflammatory effects were demonstrated at 200 µg/mL in laboratory cells, and anxiolytic properties only in rats at 200 mg/kg doses. More rigorous human research is needed before firm conclusions can be drawn about its efficacy and safety in people.

### Which form of Euphorbia hirta is most bioavailable—dried herb, extract, or standardized preparation?

No comparative bioavailability studies exist for different Euphorbia hirta forms in humans. Standardized extracts may offer more consistent active compound concentrations than whole dried herb, but absorption data and optimal dosing forms remain undetermined. Until human pharmacokinetic studies are conducted, efficacy claims about specific formulations cannot be reliably substantiated.
