@midsfactory has it right.
You are conflating extraction & distillation.
There is no requirement to make distillate for your relatives. Crude ethanol extract may well have better medicinal properties than “distillate”.
See: The "Entourage Effect" debate
For primary extraction, see Bucket Tek (Cold Ethanol Extraction on a Budget)
