What is Oregon Grape?

Oregon grape is a plant. The root and root-like stem (rhizome) are used to make medicine.

Oregon grape is used for stomach ulcers, gastroesophageal reflux disease (GERD), stomach upset, as a bitter tonic, to treat infections, and to cleanse the bowels.

Oregon grape is applied to the skin for a skin disorder called psoriasis and as a disinfectant.

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.
  • Heartburn.
  • Stomach upset.
  • Other conditions.
More evidence is needed to rate the effectiveness of Oregon grape for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
