Celery contains some butylphthalide, which has the effect of assisting in lowering blood pressure, but the effect of lowering blood pressure is weak and cannot be achieved by consuming celery alone to control blood pressure. Celery is a good product to assist in lowering blood pressure and blood lipids, and is a good ingredient for patients with cardiovascular and cerebrovascular diseases, and can be used as a dietary treatment to assist in controlling the disease state. However, relying solely on celery can not achieve the purpose of treating the disease, blindly listening to biased prescriptions without receiving regular treatment often leads to adverse consequences; especially for patients at high risk of hypertension at the third level, if they do not receive medication, even leading to complications such as cerebral hemorrhage, which can be life-threatening in serious cases. In conclusion, according to the different conditions of patients, doctors will make reasonable treatment plans. Some patients with Grade 1 hypertension can also have their blood pressure controlled smoothly through life interventions, such as diet and exercise. However, if it is still not effective in 3 months, medication should be given.
