griffen1977, the advantage to travel would not be in gathering knowledge from around the world (a time-traveling doctor would already have more of that than the entire world combined), but rather gathering pharmaceuticals. There are some plants which have useful medicinal properties in their natural form, and others which can be easily processed into useful forms (as well as some that are processed only with difficulty, but those aren't relevant here). But the problem is that those useful plants grow in many different places.
