Celery is sweet and cool in nature. Celery has sedative function and is suitable for vertigo and headache due to hypertension (high blood pressure) but not suitable for headaches caused by low blood pressure. Celery can also help to detoxify the body, especially when trying to reduce cholesterol, moving the bowels and cooling heat in the body. For those who have had a toxic lifestyle with too much alcohol, smoking, caffeine etc, then celery can help balance the body and dispel the poisons and toxins.
