What is Agathi (Sesbania grandiflora)?
Agathi, scientifically known as Sesbania grandiflora, is a fast-growing, deciduous tree native to Southeast Asia and parts of India. Commonly referred to as the vegetable hummingbird or Agathi keerai, its young leaves, pods, and distinctive large flowers are all edible and have been a staple in traditional cuisines and medicines for centuries. This versatile plant is prized not only for its delicate flavor when cooked but also for its exceptionally dense nutritional profile.
Core Macronutrients in Agathi
The nutritional richness of Agathi is evident in its macronutrient composition. For every 100 grams of its leaves, Agathi offers a substantial amount of energy, protein, and dietary fiber. This makes it an excellent addition to vegetarian and vegan diets looking for a complete source of essential amino acids.
- Protein: At approximately 8 grams per 100g, Agathi leaves provide a significant plant-based protein source. Importantly, this protein includes all eight essential amino acids, making it a complete protein similar to those found in meat and dairy.
- Carbohydrates and Fiber: With about 12 grams of carbohydrates and 2 grams of dietary fiber per 100g, Agathi supports energy needs and promotes healthy digestion. The high fiber content aids in relieving constipation and maintaining gut health.
- Fat: Agathi is a low-fat food, with only around 1 gram of fat per 100g of leaves. This makes it a heart-healthy dietary choice, fitting for those watching their fat intake.
Key Vitamins and Minerals
Beyond its macronutrients, Agathi is a powerhouse of essential micronutrients that contribute to its numerous health benefits. These include a remarkable concentration of calcium and a healthy dose of vitamins.
- Calcium and Phosphorus: Agathi is one of the highest plant-based sources of calcium, providing a staggering 1130 mg per 100g. This, combined with its high phosphorus content (80 mg per 100g), is crucial for maintaining strong bones and preventing conditions like osteoporosis.
- Iron: An excellent source of iron, Agathi leaves help prevent anemia and boost red blood cell production, leading to increased energy and reduced fatigue.
- Vitamins: The plant is loaded with vital vitamins, including Vitamin A, Vitamin C, folate, thiamin, and niacin. Vitamin A is essential for eye health, while Vitamin C and other antioxidants strengthen the immune system and protect cells from damage.
- Other Minerals: Agathi also contains important trace minerals like magnesium, potassium, and selenium, which play roles in metabolism, muscle function, and antioxidant defense.

How to Prepare and Use Agathi
Agathi can be incorporated into your diet in several delicious ways. The leaves and flowers are the most commonly used parts. For best results and to moderate the natural bitterness, consider these preparation tips:
- Stir-fries and Curries: The leaves and young pods can be sautéed with spices, onions, and garlic to create flavorful stir-fries or added to curries and soups.
- Poriyal: A popular South Indian method, Agathi poriyal involves stir-frying the leaves with grated coconut and other seasonings.
- Herbal Tea: The leaves can be dried and ground into a powder to be brewed into a nutrient-rich herbal tea.
- Soups and Salads: Add fresh, cleaned leaves and flowers to soups or salads for a nutritional boost. Removing the stamen and calyx from the flowers can reduce bitterness.
It is important to consume Agathi in moderation. Traditional practices, particularly in Ayurveda, suggest consuming it every couple of weeks, rather than daily, to avoid potential side effects and allow the body to balance its effects. It is also advised to consult a healthcare professional before use, especially if you are on medication, as it may interfere with some drug efficacies.
