I've preserved the root system of a grass plant by consolidating
with methylcellulose, with satisfactory results.  I would suggest
testing spray consolidation with either methylcellulose or Klucel-G
or GF in ethanol, probably around 3%-5%. Consolidation by immersion
might not work in this case due to the fragility of the leaves. The
difficulty in this case would be achieving access to all or most of
the surfaces of the hand, especially near where it is tied together.
Normally tobacco leaves are resinous and sticky, but since they are
as dry as you describe, consolidation should work. Let me know if
you have any questions.
