Lumbar spinal stenosis belongs to the category of lumbago in Chinese medicine, and turtle shell is effective in relieving lumbago caused by blood stasis or deficiency of yin in the liver and kidney. However, the efficacy of a single Chinese medicine is limited, and it should be combined with other Chinese medicines after identification by a Chinese medicine practitioner. Turtle shell has the effects of nourishing yin and submerging yang (suppressing too much rising yang by replenishing yin fluid), subduing heat and removing steam, and softening and dispersing knots (softening and dispersing hard lumps). It is commonly used clinically for treating yin deficiency with fever, yin deficiency with hyperactivity of yang, dizziness, menstrual closure, and obstruction in the abdomen (the appearance of tangible or intangible lumps in the abdomen with a feeling of distension and pain). Turtle shell is contraindicated in patients with deficiency of spleen and stomach, with loose stools (thin and unformed feces) and pregnant women. Patients with lumbar spinal stenosis are advised to consult a doctor and take medication as prescribed by the doctor. If you need to use turtle shell, you must use it under the guidance of a professional doctor.
