Wincarnis is a tonic wine which apparently is still produced. It was popular in places like Singapore where Chinese used it to give women a “boost” after they had given birth. According to this advertisement, however, it also had an important function prior to that point as well. In particular, the advertisement says that if a mother and father regularly drink Wincarnis, not only will they be strong and healthy, but they will definitely have many sons too. Judging from the picture in the advertisement below, it looks like it really worked! “Here, honey, have some more. . .”
