Dazhu Hongjingtian injection attenuated alcohol-induced depressive symptoms by inhibiting hippocampus oxidative stress and inflammation through Nrf2/HO-1/NLRP3 signaling pathway.

Ethnopharmacological Relevance: Alcoholic depression, a disorder of the central nervous system, is characterized by alcohol abuse, which causes blood-brain barrier disruption and oxidative damage in the brain. The rhizome of Rhodiola crenulate, from which Dazhu Hongjingtian Injection (DZHJTI) is derived, has been traditionally employed in ethnopharmacology to treat neurological disorders due to its neuroprotective, anti-inflammatory, and antioxidant properties. However, the exact mechanism by which DZHJTI alleviates alcoholic depression remains unclear.
