How is BLUE #2 made?
A variety of plants, including woad, have provided indigo throughout history, but most natural indigo is obtained from those in the genus Indigofera, which are native to the tropics. In temperate climates indigo can also be obtained from woad (Isatis tinctoria) and dyer's knotweed (Polygonum tinctorum), although the Indigofera species yield more dye. The primary commercial indigo species in Asia was true indigo (Indigofera tinctoria, also known as Indigofera sumatrana). In Central and South America the two species Indigofera suffruticosa (Anil) and Indigofera arrecta (Natal indigo) were the most important.

I jumped on this page of info because a bottle of Vitamins, I just opened had Blue #2 in it. Why do we need artificial color in a vitamin...if the natural color is brown, grey.. whatever.. so be it. I\'m taking a vitamin or eating a food to be \"healthy\"...not to have it look prettier and then cause Cancer. Leave he dye\'s OUT.
I just found out I'm sensitive to blue #2 and red #3 and need to avoid them. I guess I will find out what food and other products it is in and will be avoiding those things.
