The in vitro outcomes showed potent anticancer effect against both DLA and EAC cell lines.
Antiasthmatic Activity: An ethanolic extract of Euphorbia hirta inhibited the contractile effect of histamine in the histamine induced contraction in isolated goat tracheal chain. The antiasthmatic activity increased with increasing concentration of the extract. Flavonoids, glycosides, and saponin might have contributed to the observed antiasthma activity.
Anti-Stress / Bioflavanoid: Quercetin: Quercetin, isolated from a hydroalcoholic extract of leaves of E. hirta was evaluated for antistress potential using elevated plus maze (EPM) model and forced swimming test (FST) in Swiss albino mice. Results showed the Quercetin to be a novel compound for the treatment of neurobiological disorder (stress).
Neurophysiological Effects: Study of a lyophilized aqueous extract for E. hirta did not show anticonvulsant effects and no muscle relaxant effects. Although it did not have its own hypnotic effect in mice, it intensified those of barbiturates. Although it did not have neuroleptic activity, it had slight anti-depressant effects against reserpine induced ptosis and oxotrimorine-induced hypothermia.
Effect on Arthritis and Cartilage Degeneration: Study investigated the effect of water extracts of E. hirta on histological features and expressions of matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs) in articular cartilage. E. hirta displayed dose-dependent effects on MMP-13 and TIMP-1 levels. These are mediators involved in the pathogenesis of arthritis. Results suggest E. hirta may be a viable alternative to arthritis treatments.

• Use of Euphorbia hirta in Dengue Treatment in Indigenous Communities in Pangasinan: Study documented the anectodal and traditional self care uses of Euphorbia hirta in the treatment of dengue in 3 indigenous communities in Pangasinan from April to June 2015 according to demography, relative importance and FL. The most widely used dosage forms were decoctions of leaves and bark. Study found E. hirta to be effective against most symptoms of dengue in the initial, febrile, and recovery stages. (65)
• Tawa-tawa Active Ingredients in DHF: Study evaluated tawa-tawa's curative properties in a rat model mimicking dengue hemorrhagic fever with thrombocytopenia induced by ethanol, chloramphenicol, and heparin. The tawa-tawa decoction increased by platelet count by 47% depending on the drug used to induce thrombocytopenia, bleeding time was decreased to 62% while blood clotting time decreased to 58% compared to control. Study proposes that tawa-tawa promoted cell production and prevented platelet destruction. The platelet effect was attributed to phenolic constituents. (66)
• Antimicrobial / Flavonoids: Study evaluated the antimicrobial activity of flavonoids of E. hirta by disc diffusion assay against four bacteria (E. coli, P. aeruginosa, P. mirabilis, and S. aureus) and four fungi (A. flavus, A. niger, T. mentagrophytes, and C. albicans). Bound flavonoids extract of roots showed best activity against C. abicans. None of the tested extracts showed activity against the other three fungi tested. Total activity of free flavonoid extract was the same for P. mirabilis and S. aureus (192.30 ml/g). Results showed good antimicrobial activity with low range of MICs. (67)
• Potential Use for Dengue / A Systematic Review of Scientific Evidence: According to the review, existing evidence supports the increase of platelets and antiviral activity of E. hirta extracts. However, the studies are inadequate to establish clinical use of the plant. Furthermore, the mechanism for platelet effect have to be identified, and the effect on vascular leakage, the main pathological indicator of severe dengue, need corroboration to justify its use. Well controlled, double-blind clinical trials are suggested. (68)
• Radical Scavenging / Cytotoxicity: Study evaluated different fractions of E. hirta for radical scavenging activity using DPPH assay and cytotoxitiy using Sulforhodamine B (SRB) assay against liver (Juh-7) and lung (A-549) cell carcinoma. An ethyl acetate fraction showed potent radical scavenging activity (IC50 5.4 ± 0.65 µg/ml and IC90 11.9 ± 0.84 µg/ml) with highest potency against Huh-7 (IC50 36.7 ± 1.02 µg/ml) and A--549 (IC50 114.4 ±0.78 µg/ml) cancer cell lines. Results were attributed to high flavonoid content (23 ± 1.06 mg/g quercetin equivalent) along with high phenolic content (88.9 ± 0.57 mg/g gallic acid equivalent). (69)
• Toxicity Concerns on Use of E. hirta in Newborns for Treatment of Jedi Jedi: E. hirta is used in Nigeria for the treatment of Jedi Jedi, an infection in newborns, manifesting on the skin as pimples. This study investigated the plant for its acclaimed potency and safety. Powdered plant material yielded tannins, phenols, alkaloids, cardiac glycosides, anthraquinones cyanogenic glycosides, saponins, and flavonoids. Results showed the extract showed potent activity against various bacteria associated with"Jedi Jedi" infection (E. coli, B. subtilis, P. mirabilis, S. typhi) in newborns. In this study, toxicity to the liver was noted. Study cautions that the use of extracts of E. hirta as oral medication, both short-term and long-term was not safe, due to the presence of toxic constituents. (70)
• Safety of Plant Decoction in Folkloric Alternative Medicine: Study evaluated the safety of the traditional decoction preparation of E. hirta on its effect against normal gastrointestinal microflora. Antibacterial activity was done using disc diffusion method. Results showed no zones of inhibition against tested bacteria i.e., E. coli, S. aureus, B. subtilis, and P. aeruginosa. Study suggests safety for use of tawa-tawa decoction for oral intake without risks of altering the normal flora of microorganisms in the gastrointestinal tract. (71)
• Cardioprotective / Thrombolytic: Study evaluated various fractionated extracts from whole plant of E. hirta for phytochemistry and thrombolytic effect. Results demonstrated thrombolytic activities of various extracts. Ethanol, ethyl acetate, and water extracts exhibited clot lysis of 25.81%, 14.17%, and 30.48%, respectively. Results suggest potential as thrombolytic moiety for treatment of atherothrombotic diseases. (72)
• Sedative / Hypnotic / Leaves: Study evaluated ethanol and aqueous leaf extracts of E. hirta for sedative activity using phenobarbitone-induced sleep model in rat. Doses of 100 mg/kg and 200 mg/kg produced significant onset of sleep and duration of sleep (p<0.01). Results suggested sedative and hypnotic activities. Effect was rapid, long-lasting, and statistically significant at doses tested. (73)
• Antibacterial / Flavonoid Extracts: Flavonoid extracts from E. hirta were screened for antibacterial activity by disc diffusion assay. The highest inhibition zone (IZ) of 17 mm and AI 0.607 was shown by bound flavonoids of leaves against Agrobacterium tumifacians. Bacillus subtilis was most sensitive to flavonoids (free and bound) compared to other bacteria. (74)
• Effects on Ultrastructure of Murine Organs: Study evaluated the effect of E. hirta on the ultrastructure of murine liver, kidney, and aorta or male Sprague-Dawley rats. The aorta showed no structural changes. Renal and hepatic tissues demonstrated dose-dependent injuries, with structural damage beginning in the nuclei and spreading outwards. The herb may have effects similar to those of the quinolone group of antibiotics. Study suggests consumption of E. hirta may be associated with side-effects, and further investigations are warranted. (75)
• Lactogenic / Antioxidant: Study investigated the effect of E. hirta on milk production, antioxidant property, and acute and subacute oral toxicity. The plant exhibited strong antioxidant potential on DPPH, FRAP, and lipid peroxidation assays. Toxicity testing showed no mortality or signs of toxicity or changes in hematologic or biochemical parameters at test limit of 2000 mg/kbw by OECD guidelines. Extract treated rats produced high milk than blank and reference controls, suggesting presence of phytochemical compounds which may stimulate milk production in mammalians. (76)
• Zinc Oxide Nanoparticles: Study reports on ecofriendly, simple and easy biosynthesis of zinc oxide (ZnO) nanoparticles using leaf, stem, roots, and inflorescence of E. hirta. The ZnO NPs can be exploited for formulations of antibacterial and antifungal medicines. (78)
• Wound Healing / Antibacterial Against Surgical Wound Pathogens / Leaves and Stems: Study evaluated methanolic and aqueous extracts of leaves and stems of E. hirta for antimicrobial activity by agar well diffusion method against bacterial isolated from surgical wounds viz., E. coli, P. aeruginosa, P. mirabilis, and S. aureus. Results showed significant inhibitory effect on most the test bacteria, especially P. mirabilis. The methanol extract showed greater efficacy than the aqueous extracts. At concentration of 150 µL, the extracts showed more effect than antibiotics on most bacterial species. (80)
• Antipsoriasis / Antioxidant / Antimicrobial / Aerial Parts: Study evaluated the antipsoriatic efficacy of E. hirta as antipsoriatic. The IC50 of ME of aerial parts were 72.20 µg/mL, 97.88 µg/mL, 55.88 µg/mL, and 36.31 µg/mL by DPPH, superoxide radical scavenging, phosphomolybdenum reducing, and ferric reducing power assays. Antipsoriasis activity by MTT method showed a maximum cell death of 88.37% at 0.781 µg/mL concentration and IC50 of 12.20 µg/mL. (81)
• Anti-Inflammatory / Anxiolytic / Neonatal Asthmatic Rats / Leaves: Study evaluated the anti-inflammatory and anxiolytic activities of E. hirta leaf extract in neonatal asthmatic rats. Anxiolytic activity was evaluated by open field test, elevated plus maze, hole board test, and cross test. In this study, antioxidant activity of the ME was attributed to bioactive compounds (phenolic compounds, 9,12,15-octadecatrien-1-ool, squalene, among others). Lung histopathological exam confirmed severe inflammation in asthma-induced rats. Treatment with E. hirta extract significantly attenuated inflammation and eosinophilic infiltration.
