Track Kulattha with reminders and record whether it helped, in the app.
Kulattha is the dried seed of the horse gram plant (Macrotyloma uniflorum). People across India eat it as a pulse. In Ayurveda it is also used on its own as a medicine.
Tradition treats it as a food-medicine. It is best known for these uses: - urinary stones - too much body weight - states blamed on cold and sluggishness
It reaches you in many forms. These include whole beans, split dal, flour, a thin soup, or a water brew (kashaya).
Old texts call it heating and drying. So they suggest it for damp, heavy states. They warn against it in heat, acidity and bleeding.
The honest verdict: Kulattha has deep, unbroken standing in Ayurveda. It is also a good, nourishing pulse. But strong human trials of it as a medicine are very thin.
Long use tells you what people have done for ages. It is not proof that a remedy works. That point applies to everything below.
No one has shown clearly how Kulattha works as a medicine in people. The ideas below sound likely. Most have only been tested in the lab.
It is a pulse that is high in fibre and protein. So a meal built around it digests slowly.
That may soften the rise in blood sugar after you eat. It may also help you feel full. This is the usual reason given for its use in weight and blood sugar.
Lab and animal work has looked at kidney stones. It hints that compounds in horse gram may slow the clumping of calcium oxalate crystals. These crystals are the most common stone material.
This has not been confirmed in people. So treat it as an idea, not a finding.
Common forms: - Whole dried beans, cooked long and slow as a dal or stew - Split dal, which cooks faster - Roasted seed powder or flour, stirred into water, buttermilk or soups - Kashaya or kwath, a water brew of the crushed seed - Rasam, a thin spiced soup and the usual South Indian home form - Capsules and standard powders sold as supplements
Traditional practice always cooks the seed. Some regions do eat sprouted horse gram. Even then it is usually steamed or cooked, not raw.
Kulattha appears by name in the classical Ayurvedic texts. These include the Charaka Samhita and the Sushruta Samhita. There it sits with the pulses used for ashmari (stones in the urinary tract) and for kapha and vata states.
Farmers in India have grown it for thousands of years. It does well on dry, poor soil.
It is still both a staple food and a home remedy. You see this in South India, Maharashtra and the Himalayan foothills. That is unusual, and it is part of why its traditional standing is strong.
See a doctor promptly if you get severe pain in your side or lower back, blood in your urine, pain when passing urine, or you cannot pass urine at all. These point to a stone or infection that needs proper treatment, not a home remedy.
Book an appointment if a joint becomes suddenly hot, red and very painful, if you get persistent heartburn or stomach burning, or if you have diabetes and your blood sugar readings start running unusually low.
Get emergency help for signs of a serious allergic reaction: swelling of the lips, tongue or throat, a spreading rash, or trouble breathing.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Kulattha is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
