The recommended dosage of turtle shell in vinegar is 10 to 25 g. The exact dosage varies from person to person, and a Chinese medicine practitioner must choose the appropriate dosage according to the specific condition. Vinegar turtle shell is an alternative name for turtle shell, which is a yin tonic Chinese herbal medicine. Usually, the recommended dosage of turtle shell is 10-25g, which should be decocted first. However, as each patient’s condition is different, the dosage of turtle shell has obvious individual differences and cannot be generalized. With a salty taste and slightly cold nature, turtle shell belongs to the liver and kidney meridians, and can nourish yin and submerge yang, soften and disperse knots (soften and dissipate hard lumps), and reduce fever and remove steam. It can be used clinically for treating yin deficiency of the liver and kidneys (deficiency of yin in the liver and kidneys), and obstruction of obstruction of the masses (the appearance of tangible or invisible lumps in the abdomen, with a feeling of distension and pain) and other conditions. Pregnant women should use this medicine with caution. When the patient is not feeling well, he/she needs to go to the hospital for consultation and treatment by a doctor, and should not use the medicine by himself/herself.
