Which Chinese medicine can protect the fetus

For some of the traditional Chinese medicine for the prevention of pregnancy, we are generally divided into the following categories in clinical practice, because we know that the kidney governs the fetus and the innate spleen governs the acquired, so we use more traditional Chinese medicines for tonifying the kidney and spleen.
