Lorraine:
LOML and I have a pecan bedroom suite (dresser, chest of drawers and 2 "commodes" ie bedside table/drawer units) made of solid pecan we bought in 1976. It was and is not finished on the inside. It survived 3 years in non-climatic controlled storage in Louisiana while we were overseas, many years in non-central A/C houses where the bedrooms were not heated or air conditioned, and shipping in furniture trucks from LA to CA to FL to NC (and yes all the movers cussed us because of the weight). It still has the original finish and the only problems I have is just this past year, I have noticed the glue giving up on one of the "commodes".
I would not put poly inside because of the odor which will take quite a while to dissipate (about six months judging by some end tables I made for our living room).
If you do want to seal the wood or drawer interiors, i would suggest rattle-can lacquer spray or shellac, and give them a week or so to air out.
