I understand that wild roots are much lighter than cultivated roots, and can be hand-sliced using kitchen knife.
I've been slicing some dry wild roots recently from the same batch and found some to be firm, with clear center ring and whitish flesh throughout, but there were some that seems to be discolored (light tannish brown without visible brown ring), and a little honeycomb, corkish like. These were from good size roots with long necks, easily over 10yrs.
Are the roots with the honeycomb corkish texture diseased? They seems to look fine from the outside.
I'll try to post some photos of the slice roots later. Any feedback would be appreciated. Thanks.
