best way to use whole plant fresh ginger and turmeric?

We are probably getting a garden frost tonight so Ive picked and cleaned up all the ginger and turmeric I've had out this summer.
From what I've read, both types of leaves are edible. They smell lovely and fragrant.

We love Asian foods so prepping for that is helpful. My mother has bad osteoarthritis and I'd like to have some easy herbal drink options for her.

What I am considering: Chop the leaves and freeze everything. Put all of the roots and leaves, along with lemons and pepper into the pressure cooker and then freeze doses of it. Grind up at the fresh roots, with lemons and pepper and freeze it in tiny cubes while chopping and freezing the leaves for cooking/teas.

Has anyone tried versions of any of these options? Any other suggestions?
Thanks!
