Well,Kawaii,let's see if we can put you on the right path.
First of all,everything of vegetable matter that grows is a herb!
So, the basic herb? That's grass!
From the basic grass (that green stuff that the cows eat!) we get Wheat,Corn,Barley,Oats,Rye,Rice; and of course, Bamboo!
Now,the other "basic" herbs are ones that are used in their "normal" state; such as Sage,Lavender, Rosemary, and all the other "herbs".
Do herbs have "magical powers"? Yes, they do! Just about all medicines started off as herbs.
