All about kulekhara leaves, often consumed in ‘Bengali households as a home remedy to boost haemoglobin'

In recent years, traditional herbs and forgotten greens have gained renewed attention in the world of nutrition. One such herb is kulekhara, also known as Hygrophila schulli. To gain a deeper understanding of the benefits of this herb, we consulted with experts. 'Long used in indigenous systems of medicine across India and Bangladesh, kulekhara has earned a reputation for its potential role in treating iron-deficiency anemia, a condition that affects millions of Indians, particularly women and children,' said clinical dietitian Garima Goyal.
What is Kulekhara?
Kulekhara is a semi-aquatic plant that grows in marshy regions, especially in eastern India. 'In Bengali households, it's often consumed as a leafy decoction or juice, passed down through generations as a home remedy to boost haemoglobin,' said Goyal.
When consumed regularly, especially as a decoction or boiled extract, it can support hemoglobin production and raise red blood cell count, said Dt. Gulnaaz Shaikh, chief dietitian, KIMS Hospitals, Thane. 'Its natural iron is better absorbed when taken with vitamin C-rich foods like lemon or amla,' said Shaikh.
Nutritional value
Goyal said that the leaves are a source of iron, flavonoids, and other antioxidants that may support blood health. 'Some animal studies have demonstrated significant increases in haemoglobin and red blood cell (RBC) count in rats treated with kulekhara extract, suggesting a possible hematinic effect (blood-building property),' Goyal said.
A 2015 study published in the International Journal of Pharmaceutical Sciences and Research found that aqueous extracts of Hygrophila schulli leaves showed promise in correcting anemia in animal models. The mechanism is believed to be two-fold:
*Providing bioavailable iron in plant-based form.
*Enhancing iron absorption and improving erythropoiesis (RBC formation).
While scientific validation in human trials remains limited, anecdotal use and regional practices underscore kulekhara's significance in rural diets, experts suggest. 'Many women recovering from postpartum blood loss or those with low haemoglobin levels have traditionally been given Kulekhara decoctions as part of recovery protocols,' said Goyal.
In addition to boosting hemoglobin, kulekhara supports overall blood health and immunity. According to Shaikh, it helps reduce fatigue, improves oxygen flow in the body, and promotes clearer skin. 'Some studies suggest it may have anti-inflammatory and detoxifying properties. Its iron, folate, and chlorophyll content make it especially effective at reversing mild to moderate anemia when taken consistently,' said Shaikh.
How to use?
Always ensure the leaves are thoroughly washed and come from clean, chemical-free areas. 'Boil a handful of fresh leaves in water, let it reduce slightly, strain, and drink it on an empty stomach. It is important not to overconsume; once a day is enough. Avoid using aluminum utensils for boiling since they may interfere with iron absorption,' said Shaikh.
Visible improvements in 'energy and blood parameters may start within 3 to 4 weeks of consistent use', Shaikh said. 'However, it works best as part of a balanced iron-rich diet, which includes sources like jaggery, dates, lentils, and green vegetables,' added Shaikh.
What to note?
While kulekhara can serve as a complementary approach, it is 'not a substitute for iron supplements in clinically diagnosed anemia', Goyal asserted. 'Its use should be guided by a qualified healthcare provider or clinical dietitian—especially in vulnerable populations like pregnant women, lactating mothers, or those with chronic deficiencies,' said Goyal.
Individuals on iron medication or those with chronic kidney disease should talk to a doctor before using it regularly, Shaikh added.
