What side effects this plant can have?
This plant can cause significant health complications such as constipation, cough, dysentery, gout, and testicular degeneration. While used in traditional medicine, excessive consumption may lead to severe gastrointestinal issues like chronic constipation or bouts of dysentery. Respiratory irritation can manifest as a persistent cough in some individuals. Furthermore, certain components in the plant are linked to metabolic complications like gout. Most critically, prolonged or improper use has been associated with serious reproductive damage including testicular degeneration.
According to a study published by "BMC complementary medicine and therapies", the aqueous-methanol extract of Euphorbia hirta (EH.Cr) at doses of 500 and 1000 mg/kg showed 41 and 70% protection from castor oil-induced diarrhea. However, at lower doses of 50 and 100 mg/kg, EH.Cr caused an increase in fecal output. In loperamide-induced constipated mice, EH.Cr displayed a laxative effect with values of 28.6 and 35.3% at 50 and 100 mg/kg respectively. The crude extract possesses an antidiarrheal effect mediated through Ca++ antagonist like gut inhibitory constituents, while its laxative effect was mediated through muscarinic receptor agonist like gut stimulant constituents. These findings provide evidence for the use of E. hirta in treating diarrhea and constipation.
