Network pharmacology and in silico docking analyses have uncovered the multi-target mechanisms by which Chitraka treats hemorrhoids (piles). Bioactive root compounds selectively bind to core target proteins including PIK3CA, EGFR, PRKCA, VEGFA, MMP-9, and NOS2. This modulates cell migration, population proliferation, and vascular remodeling, directly suppressing the pathological angiogenesis and abnormal vasodilation that drive hemorrhoidal development. | |||
