Celery belongs to the Apiaceae family, which includes carrots, parsnips, parsley and celeriac. Its crunchy stems make this vegetable a popular low-calorie snack and may offer many health benefits.
reduce blood pressure
Some herbalists use celery and its extract to lower blood pressure.
One study examined the effects of celery seed extract on blood pressure in normotensive and/or artificially induced hypertensive rats.
The authors concluded that the extract lowered blood pressure and increased heart rate in hypertensive rats, but not in normotensive rats.
It is also a good source of fiber, and a 2016 Cochrane review found that people with high fiber intake may have lower blood pressure than those on low-fiber diets.
Hyperlipidemia refers to an increase in fat molecules in the blood. Although it is often asymptomatic, it increases the long-term risk of heart disease and stroke.
A 2014 rodent study found that celery extract reduced levels of low-density lipoprotein (LDL), or “bad” cholesterol, in rats fed with a high-fat diet.
A 2016 Cochrane review found that people with a high-fiber diet appeared to have lower total and LDL cholesterol levels than those with a low fiber intake.
Apigenin can also stimulate neurogenesis, the growth and development of nerve cells.
In a 2009 study, researchers gave rats apigenin. They found that it stimulated the formation of nerve cells and improved learning and memory.
Some researchers suggest that celery extract may also help prevent:
- liver disease and jaundice
- urinary tract obstruction
- rheumatic disorders
