Celery is a diuretic, which can assist the action of hypertension medications, states HealthCentral. However, celery contains sodium, which in large quantities can raise blood pressure. Results of studies that claim that celery lowers blood pressure have been criticized. The experiments were performed under controlled conditions on laboratory animals who were fed celery extract.

The blood pressure-lowering benefits of celery are restricted to celery seed or extract, according to the World's Healthiest Foods. Celery has other benefits. It contains vital antioxidants and nutrients, justifying its appearance on the World's Healthiest Foods website. Celery has an anti-inflammatory effect on the digestive tract and stomach lining, decreasing the risk of developing an ulcer. Celery's anti-inflammatory properties also provide cardiovascular support, as inflammation can lead to various diseases over time.

While little research has been done on celery's cancer-fighting properties as of 2015, the World's Healthiest Foods points out that celery reduces oxidative stress and inflammation, both of which are risk factors for the development of various cancers.
