Korean Angelica (Angelica gigas) has a long history of use in traditional Korean medicine, including for liver-related ailments such as hepatitis. In traditional practices, it is believed to "nourish the blood," "move qi," and support the health of various organs, including the liver. This has led to its use in herbal formulas aimed at improving symptoms associated with hepatitis, such as fatigue and jaundice.

Scientific research on Korean Angelica's efficacy in treating hepatitis is limited and primarily preclinical. Some studies have investigated its active compounds, such as decursin and decursinol angelate, for their anti-inflammatory and antioxidant properties, which could theoretically benefit liver health. However, there are no well-designed, large-scale clinical trials directly supporting its use for hepatitis in humans. Most available evidence comes from cell or animal studies, which have shown some hepatoprotective effects, but these results cannot be directly extrapolated to human hepatitis treatment.

Overall, the use of Korean Angelica for hepatitis is primarily rooted in traditional medicine, with limited scientific evidence and a lack of robust clinical data to validate its effectiveness for this specific condition.
