Possibly Effective for...
- Psoriasis. Some evidence suggests that applying a specific 10% Oregon grape extract cream (Relieva by Apollo Pharmaceutical) can reduce the severity of psoriasis and improve quality of life for people who have psoriasis. It might be as effective as the medication calcipotriene (Dovonex) cream for some people.
Insufficient Evidence to Rate Effectiveness for...
- Itchy and inflamed skin (eczema). Early research suggests that applying a specific Oregon grape extract cream (Relieva by Apolla Pharmaceutical) for 12 weeks might improve the severity and area of itchy and inflamed skin in people with a skin condition called eczema. However, other research shows that topical application of a cream containing Oregon grape, heart's ease, and gotu kola extracts does not improve eczema.
- Stomach ulcers.
- Stomach upset.
- Other conditions.
More evidence is needed to rate the effectiveness of Oregon grape for these uses.
