My 2 cents on this topic is: CALAMANSI JUICE can be made from calamansi fruit which is abundant in the Philippines. If you have colds, calamansi juice is good for you to drink with a little sugar in it to cure your colds. Calamansi juice can also add as seasoning for a lot of food like sinigang, or stew. Calamansi juice is a great source of Vitamin C.
