Our friend Ronnie Arco of Weambard International Traders tells us that Calamansi puree is used by Korean women to enhance their beauty. In the morning, before breakfast, they take a jigger of calamansi puree. They believe that this gives them detox that results in glowing skin.
On the other hand, the Korean men who enjoy drinking in the evening, adds calamansi puree to their rice wine. It gives them a very desirable flavor to their otherwise bland rice wine.
Maybe, you should try either or both whether you are a man or a woman.
