1. Lowers Inflammation

Celery contains antioxidants and polysaccharides that are known to act as anti-inflammatories, especially flavonoid and polyphenol antioxidants. These support overall health, especially as someone ages, by fighting free-radical damage (or oxidative stress) that can lead to inflammation. Inflammation is often a contributing cause of chronic diseases like cancer, heart disease, arthritis and many more.
Researchers have identified over a dozen different types of antioxidants that are responsible for the benefits of celery — these include such phenolic acids as caffeic acid and ferulic acid, plus flavaols like quecetin. This makes celery useful for treating a wide range of conditions that are made worse by inflammation: joint pain (such as from arthritis), gout, kidney and liver infections, skin disorders, irritable bowel syndrome and urinary tract infections, just to name a few.

 2. Helps Prevent or Treat High Blood Pressure

Celery seed extracts have anti-hypertensive properties that help reduce high blood pressure, one of the important risk factors for coronary heart disease that is the largest cause of mortality in industrial countries.
Benefits of celery seeds include potentially helping to control chronic elevated blood pressure levels. (3) The blood pressure-lowering benefits of celery come from its seeds, which contain hexanic, methanolic, and aqueous-ethanolic extracts that improve circulation, lower inflammation and help control blood pressure.
When rats were given celery seed extract over a seven-week period, they experienced significant improvements in blood pressure levels compared to rats being fed the same diet but not receiving celery extract. It’s believed that celery helps lower high blood pressure by acting as a smooth muscle relaxant and improving the flow of calcium and potassium into and out of cells. Celery extract helps blood vessels to expand and contract, improve blood flow, and aid in overall heart health.

 3. Helps Prevent Ulcers

Here’s one of the benefits of celery you may not have known about: It can help prevent or reduce the formation of painful ulcers. A 2010 study published in the Journal of Pharmaceutical Biology found that celery contains a special type of ethanol extract that is useful in protecting the lining of the digestive tract from ulcers. Celery extract has the ability to significantly replenish depleted levels of gastric mucus that is needed in the stomach lining to prevent tiny holes and openings from forming.
Researchers believe celery nourishes the stomach, colon and intestines due to the presence of chemical constituents such as flavonoids, tannins, volatile oils and alkaloids that control the level of gastric acid released while also improving the level of protective mucus. (4)

4. Protects Liver Health

When researchers from the Department of Nutrition and Food Science at Helwan University in Egypt fed rats celery (along with chicory and barley), these rats experienced a reduction in the amount of dangerous fat buildup within the liver.
Precisely, when researchers supplemented the high-cholesterol diets of rats with celery, chicory and barley powder, they observed an improvement in liver enzyme function and blood lipid levels. The more celery, chicory and barley the rats were given, the more their liver health improved. This suggests that a diet high in celery, as well as chicory and barley, can be beneficial for people suffering from liver disease. (5)

 5. Beneficial for Weight Loss

Celery is extremely low in calories and can be a valuable food to help you lose weight because of its ability to provide vital nutrients and to help regulate lipid (fat) metabolism. One of the major benefits of celery is that it’s so nutrient-dense, meaning it provides antioxidants, electrolytes, vitamins and minerals like vitamin C, B vitamins and potassium – all with very little calories.
