Jackfruit (kathal) is a tree native to India. Its fruit and seeds are eaten as food. Other plant parts are used in Ayurvedic medicine.
Jackfruit leaves and roots contain chemicals that might help control blood sugar increases after eating. Its fruit is a source of vitamin A, fiber, and protein.
People use jackfruit for diabetes, wound healing, and many other conditions, but there is no good scientific evidence to support these uses.
