How did she discover Christian Science?

In 1866 she was severely injured in a fall, and turned to the Bible as she had been accustomed to doing. All she had pondered in the past came strongly and clearly to her as she read an account of one of Jesus’ healings. She was immediately healed. Convinced that God had healed her, she spent the next several years searching the Scriptures to understand the principle behind her healing. She named her discovery Christian Science and explained it in 1875 when she first wrote Science and Health.
