What are the side effects of taking evening primrose?

Possible side effects of consuming evening primrose mainly include: 1. Gastrointestinal issues: It may irritate the gastrointestinal tract, causing symptoms such as nausea, vomiting, and upper abdominal discomfort. Long-term intake may lead to impaired nutrient absorption. 2. Skin reactions: Stimulation of the immune system may result in allergic reactions such as erythema, itching, and swelling. In severe cases, anaphylactic shock may occur. 3.
