Can't you sun-dry leaves? ... on a towel, after washing, and left in the sun to dry? I would think that sun-drying will leave more of the active ingredients intact in the leaves than a low heat setting in an oven.
Might be wrong about that, but I seem to recall that's how my grandmother (we lived in a very rural place back in the day) used to dry sliced apples and such.

I wash them while still on the plant.
