The water lily (genus Nymphaea) is more than just an ornamental aquatic plant; it has a rich history in traditional medicine and is valued for its nutritional content across various cultures. From the edible seeds, known as makhana, to the nutrient-rich stems and rhizomes, different parts of the plant offer a range of benefits. Modern research continues to explore these traditional uses, identifying key compounds like antioxidants and alkaloids that contribute to its healing properties. Understanding the full scope of what are the health benefits of water lily involves looking at both its historical applications and emerging scientific evidence.
The Nutrient Profile of Water Lily
The nutritional composition of water lily varies depending on the species and the part of the plant consumed. Water lily seeds, for instance, are particularly notable for their macro- and micronutrient content.
- Carbohydrates and Fiber: The seeds are a good source of complex carbohydrates and high in dietary fiber, promoting satiety and aiding digestive health. The fiber content in stems and roots also contributes significantly to digestive function.
- Protein: The seeds and rhizomes contain varying amounts of protein, making them a useful dietary supplement in some regions.
- Minerals: Water lily parts are rich in essential minerals, including potassium, calcium, magnesium, and phosphorus. Potassium is particularly important for regulating blood pressure, while calcium and magnesium support strong bones and nerve function.
- Antioxidants: The plant is loaded with potent antioxidants, such as flavonoids and phenolic compounds, which help combat free radicals and reduce oxidative stress.
- Vitamins: The seeds and other parts contain vitamins, including vitamin C, which boosts immunity.
Proven and Traditional Health Benefits
Regulating Blood Sugar and Promoting Liver Health
Water lily extracts contain compounds like nymphayol, an alkaloid that has been shown to regulate insulin levels and stabilize blood sugar. This makes it a promising complementary remedy for managing diabetes and related metabolic disorders. Additionally, studies have suggested hepatoprotective properties, indicating the plant may prevent potential liver damage and aid in organ regeneration.
Supporting Cardiovascular and Digestive Systems
The combination of high fiber, potassium, and antioxidants found in water lily seeds offers significant support for cardiovascular health. The fiber helps lower serum cholesterol, while potassium is crucial for maintaining healthy blood pressure. The high fiber content across different edible parts of the plant, including stems and seeds, also promotes regular bowel movements and prevents constipation.
Anti-inflammatory and Soothing Properties
Traditionally, preparations from various water lily parts have been used topically and internally to reduce inflammation and soothe irritation. Ointments and extracts applied externally can relieve pain and swelling. The presence of tannins contributes to its astringent and demulcent effects, used historically for treating boils, ulcers, and sore throats.
Boosting Immunity and Energy Levels
With its content of vitamins and minerals like Vitamin C and zinc, water lily helps bolster the immune system, aiding the body in fighting off infections. The complex carbohydrates and B-complex vitamins provide a source of sustained energy, combating fatigue and maintaining optimal energy levels throughout the day.
Promoting Skin Health
Water lily extract is increasingly used in cosmetic products for its impressive skincare benefits. Rich in antioxidants, it defends against environmental stressors that cause skin damage. Its hydrating properties help the skin stay plump and smooth, while its soothing and anti-inflammatory effects make it excellent for irritated, sensitive, or acne-prone skin.
How Different Water Lily Parts Are Used
- Popped Seeds (Makhana): A popular gluten-free snack in India, these are roasted or fried and can be eaten plain or seasoned. They are also used in various curries and desserts.
- Stems and Roots: Edible and consumed in many cuisines, particularly Bengali, the stems and roots can be added to stir-fries, soups, and curries.
- Tinctures and Extracts: Concentrated forms are taken internally to regulate blood sugar and protect the liver.
- Ointments and Poultices: Applied externally, ointments and poultices made from water lily can reduce pain, swelling, and soothe skin irritations.
- Decoctions: A tea made from boiling the roots is used traditionally for internal issues like digestive troubles and for gargling.

Precautions and Safety
While edible water lily species offer many benefits, it is crucial to exercise caution. Some ornamental water lily species are toxic and should not be ingested. Additionally, water lilies grown in polluted water bodies may absorb heavy metals, posing a toxicity risk. Always source edible parts from reputable sources. Some people may experience gastrointestinal distress or allergic reactions. As with any herbal supplement, consulting a healthcare professional before use is recommended, especially for pregnant or breastfeeding individuals, or those with pre-existing health conditions.
