Its prominence in Vietnamese cuisine is evident from the rural countryside to bustling cities, and its medicinal properties are revered in traditional folk remedies.

Water celery is a staple in the daily diets of Vietnamese people, and its cultivation is facilitated by the country’s tropical climate. Homegrown water celery is readily accessible, requiring minimal care and offering year-round harvests.
Beyond its culinary applications, water celery is a veritable treasure trove of nutrients. According to nutritional experts, this vegetable boasts significantly higher levels of vitamin C compared to renowned citrus fruits like oranges and lemons.
Remarkably, water celery contains up to 10 times more vitamin B2 and 45 times more vitamin C than common vegetables. Additionally, it is a rich source of vitamins A and B, fiber, and minerals such as calcium, iron, and magnesium, offering a plethora of health benefits.
The Multifaceted Benefits of Water Celery

Detoxification and Fever Reduction: Water celery possesses a cooling nature and a sweet flavor. It aids in detoxification, promotes diuresis, helps reduce fever, and increases saliva production.
Lowering Blood Pressure: Water celery contains papaverine, a compound that induces vasodilation and counteracts smooth muscle contractions. As such, it effectively helps lower blood pressure.
Diabetes Management: For individuals with diabetes, consuming water celery is beneficial as it contains inulin, which slows down the absorption of glucose from food. Inulin also generates heat energy that is nine times lower than that produced by fats.
Weight Loss: Water celery juice is an effective way to lose weight, especially targeting abdominal fat.
Lactation Support: Water celery increases lactation in nursing mothers due to the estrogen-like effects of its chemical compounds, sterols. It also contains ephedrine, beneficial for those suffering from the flu.
Reduced Risk of Infections: Water celery is an exceptional source of vitamin C, surpassing the levels found in oranges or guavas. This makes it a scientifically recognized source of high vitamin C content, essential for wound healing, optimal brain function, and enhancing the immune system.
Boosted Immunity: The leaves of water celery are rich in vitamin A, which helps prevent eye diseases, supports cell growth, strengthens the immune system, aids in reproduction, and promotes healthy skin.
