What side effects this plant can have?
This plant can induce significant cellular changes including DNA damage, apoptosis, cell cycle arrest, and chromatin condensation while also exhibiting a potent hypoglycemic property. These biological mechanisms allow the plant's compounds to interfere with the progression of malignant cells by disrupting their reproductive processes. When the plant triggers cell cycle arrest, it prevents abnormal cells from multiplying uncontrollably. The subsequent induction of chromatin condensation and apoptosis ensures that damaged cells undergo programmed death. Additionally, its ability to lower blood sugar levels through its hypoglycemic property provides further systemic metabolic effects.
