Chop tomatoes, beetroot, carrots, ginger and coriander leaves. Add to the food mixer, add the mint leaves, cumin powder, salt, black pepper and lemon juice. Add half cup water and grind well. Pour and drink.
Optionally, garlic can also be added to the juice. Make sure you don't add a lot of water, the consistency of juice will be thick, and that's how it's going to detoxify your system.
