Some studies have found that ginseng may boost the immune system. There is some evidence that one particular type of American ginseng extract might decrease the number and severity of colds in adults. Several studies in people have also shown that ginseng may lower blood sugar levels. There is some early evidence that ginseng might temporarily -- and modestly -- improve concentration and learning. In some studies of mental performance, ginseng has been combined with ginkgo.
The Fourth of July is known as Independence Day because that is the day that the Second Continental Congress adopted the full and formal Declaration of Independence. Even though we had declared that we were independent, the American Revolution was still being fought, which meant that we were still not independent.
July 4 was intentionally chosen by the United States because it corresponds to its Independence Day, and this day was observed in the Philippines as Independence Day until 1962. In 1964, the name of the July 4 holiday was changed to Republic Day. In Rwanda, July 4 is an official holiday known as Liberation Day, commemorating the end of the 1994 Rwandan Genocide in which the U.S. government also played a role. Denmark also celebrates American independence on July 4.
