Hmmm, very interesting healing plant, never heard about this one, Although I would only use it if I had something though... I think it's a very strong anti-micro by the looks of it, fall under leaf medicine in my opinion. Similar to Wild Oregano.

You'll find they are all very similar but very unique at the same time.

The molecules are highly anti-microbe, watch out with dosage.

Watch out! E. hirta at a dose of 50 mg/kg reduced the sperm motility and density of cauda epididymal and testis sperm suspension significantly, leading to 100% infertility.[23]
Antiamoebic activity 🤣🤣

PHARMACOLOGICAL ACTIVITIES

Antibacterial activity

The ethanolic extract of E. hirta inhibited the growth of the Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Bacillus subtili[16] and aqueous and chloroform leaf extracts of E. hirta possess an antibacterial activity against Klebsiella pneumonia. The extract is noncytotoxic and antibacterial.[17]
Antimalarial activity

The bioassay-guided fractionation of the methanolic extract of aerial parts of E. hirta, monitored against P. falciparum parasites, yielded a main active chromatographic fraction showing 90% growth inhibition of P. falciparum at a concentration of 5 μg/ml.[13]
Anti-inflammatory activity

The n-hexane extract of aerial parts of E. hirta showed anti-inflammatory effects in the model of phorbol acetate-induced ear inflammation in mice. It exhibited a dose-dependent effect.[18,19]
Galactogenic activity

The powdered E. hirta showed a galactogenic activity in guinea pigs before puberty by increasing the development of the mammary glands and induction of secretion.[20]
Antiasthmatic activity

E. hirta is reported to have an antiasthmatic activity due to the relaxation effect on the bronchial tubes and a depressant action on respiration.[12]
Effect on urine output and electrolytes

Ethanolic and aqueous leaf extracts of E. hirta significantly induced diuresis in rats. The diuretic effect of the ethanol extract was significant at 6 h (for 100 mg/kg) and at 24 h (for 50 mg/kg). The water extract induced a significant increase in urine Na+, K+ and HCO3- loss. The ethanol extract (100 mg/ml) caused a significant decrease in the K+ loss whereas the water extract increased its excretion. The HCO3- urine output following the injection of both extracts was tremendously enhanced.[21]
Antidiarrheal activity

The antidiarrheal effect of the herb decoction was studied in mice. It demonstrated an activity in models of diarrhea induced by castor oil, arachidonic acid, and prostaglandin E2.[10] Quercitrin, a flavanoid glycoside isolated from E. hirta, showed an antidiarrheal activity, at a dose of 50 mg/kg, against castor oil and prostaglandin E2-induced diarrhea in mice.[11]
Antioxidant activity

The aqueous extract of E. hirta L. showed an antioxidant effect and a free radical scavenging activity in various in vitro models like total antioxidant and total ferric reducing power determination, assay for free radical-scavenging activity using ABTS, DPPH, and hydroxyl radical scavenging assays. It showed maximum antioxidants and free radical scavenging activities, at 0.25 mg/ml. The free radical scavenging effect on DPPH and hydroxyl was found as 68.80 ± 5.21 and 73.36 ± 5.21%, respectively.[22]
Antifertility activity

E. hirta at a dose of 50 mg/kg reduced the sperm motility and density of cauda epididymal and testis sperm suspension significantly, leading to 100% infertility.[23]
Antiamoebic activity

The polyphenolic extract of E. hirta inhibited the growth of Entamoeba histolytica with a minimum active concentration of less than 10 μg/ml.[8]
Antifungal activity

An ethanolic extract of E. hirta showed an antifungal activity against plant pathogens Colletotrichum capsici, Fusarium pallidoroseum, Botryodiplodia theobromae, Phomopsis caricae-papayae, and Aspergillus niger using the paper disc diffusion technique.[24]
