The group of people who should avoid eating water spinach may come as a surprise to many, as this vegetable is known for its mild nature, high fiber content, and digestive benefits. However, it’s important to understand that water spinach may not suit everyone, and improper consumption can potentially harm your health. Let’s explore this in more detail to safeguard your well-being and that of your loved ones.
1. Benefits of Water Spinach
Water spinach is a humble yet familiar vegetable in many Vietnamese households. According to the United States Department of Agriculture (USDA), water spinach is packed with essential nutrients such as sodium, potassium, fiber, protein, calcium, iron, and vitamins A, B6, B12, C, and D. Notably, it contains beta-sitosterol, a compound with anti-cancer and antioxidant properties, making it highly praised for cancer prevention, especially in the digestive tract.
A small bowl of cooked water spinach daily can provide sufficient amounts of vitamin A and iron for your body’s needs. In traditional Chinese medicine, water spinach is believed to have cooling properties, a sour taste, and no toxicity. It is used for detoxification, diuretic effects, heat clearance, skin health, and the treatment of boils and rashes.
Additionally, water spinach helps cool down the body and relieves constipation due to its high content of mucilage and soluble fiber. For those suffering from constipation, especially pregnant women, consuming approximately 500 grams of cooked water spinach regularly can be a natural alternative to laxatives.

Water spinach aids in digestion and effectively relieves constipation.
Water spinach also promotes wound healing and benefits bone and joint health. Simmering it with pork hocks helps alleviate bone pain. The extracted juice from water spinach is also applied in cases of mild burns, soothing and regenerating the skin.
In countries like Indonesia, India, and Bangladesh, water spinach is utilized as a natural remedy for constipation, anemia, infections, and digestive issues.
2. Who Should Avoid Water Spinach?
Despite its numerous benefits, water spinach may not be suitable for everyone. According to Doctor of Medicine, Huynh Tan Vu, a lecturer at the University of Medicine and Pharmacy in Ho Chi Minh City, water spinach contains significant levels of oxalic acid and purines. Excessive consumption can increase the concentration of calcium oxalate in urine, leading to its accumulation in the body and, consequently, kidney stone formation.
Moreover, the high levels of uric acid derived from purines elevate the risk of gout. Therefore, individuals suffering from kidney stones or gout are advised to refrain from consuming water spinach or to do so sparingly.

Gout patients should avoid water spinach due to its high uric acid content.
Additionally, given its cooling properties and laxative effects, water spinach is not recommended for individuals experiencing diarrhea or loose stools, as it may exacerbate these conditions.
Water spinach is a versatile vegetable that serves as both a nutritious food and a medicinal herb. However, like any other herb or food, proper and judicious use is crucial to ensuring safety and maximizing its benefits. Individuals with kidney stones, gout, or diarrhea should exercise caution when including water spinach in their daily diet.
