Kollu or Horse gram, also called Kulthi bean is used as horse feed and occasionally for human consumption and in Ayurvedic cuisine. Horse gram is grown in India, as well as in Malaysia, Sri Lanka, the West Indies, and elsewhere.
Kollu is the most protein-rich lentil found on the planet. It is very high-powered. That’s why race horses are fed with this gram, which is called horse gram in the market.
