Raw turtle shell and vinegared turtle shell are different concoctions of turtle shell with different efficacies, applicable to different types of patients, and cannot be directly compared. Turtle shell is the dorsal armor of the soft-shelled turtle (Pelodiscus sinensis), which is raw after removing the skin and flesh and drying it in the sun. After removing the skin and flesh and drying it in the sun, it is raw turtle shell. After quenching it in vinegar and drying it in the sun, it is vinegared turtle shell. Raw turtle shell has the effects of nourishing yin and submerging yang, reducing fever and removing steam, and softening hardness and dispersing knots, and can be used to treat patients with yin deficiency and wind movement. After being fried and quenched in vinegar, turtle shell becomes crispy, easy to crush and decoct the active ingredients, and can correct the odor and taste. The vinegar system also enhances the effect of the drug in eliminating liver stagnation and softening and dispersing hard lumps. It is often used in treating obstruction in the abdomen (the appearance of tangible or intangible lumps in the abdomen with distension and pain) and menstrual cramps. Raw turtle shells and vinegar-made turtle shells have different medicinal biases and are suitable for patients with different syndromes, so it cannot be assumed that one drug is better than the other, and the appropriate drug should be chosen according to the specific syndromes. Patients who need to use medication should do so under the guidance of a doctor.
