It should be true. My cousin's daughter has had a nosebleed for many years. She took a lot of medicine and saw many doctors, but she never recovered, intermittently. Later, her health became worse and worse. Later, my cousin's colleague introduced Dr. Chen's medicine to her and took it for a while. So far, I haven't heard that the child has a nosebleed. It's been almost a year. It should be cured.
