Balsam of Peru comes from the trunk of a tree grown in Central and South America. It is a natural resinous balsam that contains a mix of a number of substances that are related to Cinnamon, Vanilla and Clove fragrance and flavourings.
In the 38 states with either a four-year term or a 2-4-4 term, 27 states have staggered elections so that approximately half of state senate seats are up for re-election during the state's general elections that take place every two years.
Thus, in the U.S., no one can serve more than 10 years, up to 2 years after replacing a President in mid-term and then 8 years more if elected to two terms thereafter. In the United States, the legal limit is technically 10 years, not 8 as often but erroneously supposed.
