According to a study published by "Natural product communications", Elephantopus scaber is one of five medicinal herbs used to treat cancer in Chinese folk medicine. The ethyl acetate fraction from the ethanolic extract of Elephantopus scaber showed the highest effect with IC50 values of less than 25 microg/mL on 3 susceptible cell lines, namely, PC-3, CNE, and HL-60. Further isolation of this fraction led to the identification of 3 sesquiterpene lactones, 2 flavonoids, and 5 triterpene compounds. The sesquiterpene lactones were the most effective group with IC50 values ranging from 0.9 to 7.5 microM, while the flavonoids had IC50 values ranging from 17.3 to 42.6 microM. Among these, the sesquiterpene lactone deoxyelephantopin exhibited the strongest effect on PC-3, CNE, and HL-60 cells with IC50 values of 4.6, 2.6, and 0.9 microM, respectively.

According to a study published by "Journal of ethnopharmacology", aqueous and hydroalcoholic extracts of whole Elephantopus scaber plants tested at doses of 0.3-6 g/kg i.p. induced writhing, loss of muscle tone, ataxia, prostration, and death in mice. No analgesic effects were detected in mouse hot-plate or acetic acid-induced writhing tests, and both extracts failed to modify diuresis or carrageenan-induced rat paw edema. When given intraperitoneally, both extracts reduced brewer's yeast-induced hyperthermia in rats, though they did not affect it when given orally. The aqueous extract decreased intestinal transit time in mice, while the hydroalcoholic extract increased it. Finally, when administered intravenously, these extracts reduced blood pressure and heart rate in rats.

What side effects this plant can have?
This plant can cause severe physiological distress including ataxia, decreased intestinal transit time, diarrhea, loss of muscle tone, and prostration. These adverse effects manifest as a disruption of the central nervous system and digestive tract. The neurological symptoms lead to a lack of coordination and a significant reduction in muscular strength. Furthermore, the gastrointestinal changes result in rapid bowel movements and liquid stools. In extreme cases, these combined reactions culminate in total physical collapse and exhaustion.
According to a study published by "Journal of ethnopharmacology", aqueous and hydroalcoholic extracts of whole Elephantopus scaber plants tested at doses of 0.3-6 g/kg i.p. induced writhing, loss of muscle tone, ataxia, prostration, and death in mice. No analgesic effects were detected via mouse hot-plate and acetic acid-induced writhing tests, and the extracts failed to modify diuresis or carrageenan-induced rat paw edema. While intraperitoneal administration reduced brewer's yeast-induced hyperthermia in rats, oral administration did not affect it. The aqueous extract decreased intestinal transit time in mice, whereas the hydroalcoholic extract increased it. When given intravenously, both extracts reduced blood pressure and heart rate in rats through effects that could be blocked by atropine.
