Ovarian aging (OA) seriously affects the physical and mental health of women. Nowadays, Chinese herbs have huge appeal and potential in treating OA. We have created a new Chinese herbal combination Yijing Keli, whereas its safety and efficacy still need to be validated. Hence, we will perform a population-based, multicenter study to confirm the safety and efficacy of Yijing Keli in therapy of OA. We aim to provide a solid evidence for TCM in therapy of OA.
