Objective  In the wake of intracerebral hemorrhage ( ICH ), a devastating stroke with no effective treatment, hemoglobin/iron‐induced oxidative injury leads to neuronal loss and poor neurologic outcomes. (‐)‐Epicatechin ( EC ), a brain‐permeable flavanol that modulates redox/oxidative stress via the  NF ‐E2–related factor (Nrf) 2 pathway, has been shown to be beneficial for vascular and cognitive function in humans. Here, we examined whether  EC  can reduce early brain injury in  ICH  mouse models and investigated the underlying mechanisms.    Methods   ICH  was induced by injecting collagenase, autologous blood, or thrombin into mouse striatum.  EC  was administered orally at 3 h after  ICH  and then every 24 h. Lesion volume, neurologic deficits, brain edema, reactive oxygen species, and protein expression and activity were evaluated.    Results   EC  significantly reduced lesion volume and ameliorated neurologic deficits in both male and female  ICH  mice. Cell death and neuronal degeneration were decreased in the perihematomal area and were associated with reductions in caspase‐3 activity and high‐mobility group protein B1 ( HMGB ‐1) level. These changes were accompanied by attenuation of oxidative insults, increased phase II enzyme expression, and increased Nrf2 nuclear accumulation. Interestingly, in addition to providing neuroprotection via Nrf2 signaling,  EC  diminished heme oxygenase‐1 induction and brain iron deposition via an Nrf2‐independent pathway that downregulated  ICH ‐induced activating protein‐1 activation and decreased matrix metalloproteinase 9 activity, lipocalin‐2 levels, iron‐dependent cell death, and ferroptosis‐related gene expression.    Interpretation  Collectively, our data show that  EC  protects against  ICH  by activation of Nrf2‐dependent and ‐independent pathways and may serve as a potential intervention for patients with  ICH .
