Could Modern Medicine Still Be Used in the Tang Dynasty?

"Girl, are you awake?" A calloused hand came over, with the bitter smell of herbs in its palm. Lin Wei opened his eyes suddenly and saw an old woman wearing coarse short brown clothes, with a wooden hairpin in her bun, and a little dust in the wrinkles at the corners of her eyes. This was not the emergency room of the first city hospital where she was. In front of you is a low adobe house with a worn-out thatch roof and half a bundle of dry mugwort piled in the corner. The sunlight shines through the window lattice covered with hemp paper, casting mottled light and shadow on the ground. She moved and found herself lying on a wooden bed covered with hay, covered with a thin quilt that exuded a musty smell. "Water..." Lin Wei struggled to spit out a word as his throat was so dry that it felt like it was about to split. The old woman quickly handed over a stoneware bowl, with a small hole missing from the rim. The warm water had a faint earthy smell, but it made her wake up in an instant. "Thank you, mother-in-law." She stood up, her mind in a mess. The last memory she had was that after working a thirty-six-hour shift, she was sorting specimens in the anatomy room when a thunder suddenly struck outside the window and hit the copy of "Tang Materia Medica" that she had just bought from the ancient book market next to the window.
