Tenascin drug has been used for a longer period of time. In clinical practice, if patients have significant headache, dizziness or have significant manifestations of neurological discomfort, the use of tenascin is generally considered to relieve patients’ typical clinical manifestations such as headache, dizziness or memory loss. Because of its obvious tube-dilating effect, it has obvious efficacy in improving the patient’s blood flow and brain ischemia, so in clinical practice, asparagine is mainly used to treat headache. If patients with headache do not improve significantly with other drugs, they can inject asparagine and use a course of treatment, which may have a more desirable effect. However, not all headaches can be treated with asparagine, because there are more causes of headache, such as trigeminal neuralgia and migraine, the efficacy of using asparagine is not exact, and further treatment with other drugs may be needed. Therefore, it is recommended that patients identify the cause of the headache and carry out symptomatic treatment.
