Can I take evening primrose during my menstrual period?
Generally, it is not recommended to take evening primrose during menstruation. The detailed explanation is as follows:

Evening primrose is a traditional Chinese herb with various benefits, such as removing wind-dampness, strengthening tendons and bones, and promoting blood circulation to relieve pain. It has a warm nature and can be used to treat symptoms like rheumatic pain, joint pain, and weakness of tendons and bones, including soreness and weakness in the waist and knees. Additionally, evening primrose promotes blood circulation and helps alleviate dysmenorrhea and amenorrhea caused by blood stasis.
However, taking evening primrose during menstruation may increase menstrual flow or prolong the menstrual period due to its blood-activating effect, thereby increasing physical discomfort. Long-term or improper use of evening primrose may also cause endocrine disorders, such as menstrual cycle irregularities, which are detrimental to women's health. Therefore, it is not recommended for women to consume evening primrose during their menstrual period.
During menstruation, women are advised to maintain a balanced diet, avoid cold and spicy foods, and keep the abdomen warm to ensure a smooth menstrual period.
