I think that Jackson is right.  AFAIK all the items tagged with {naH} or {naHmey} are Terran:

 

I couldn’t find any native Klingon fruit or vegetables tagged with {naH}.  And why would they be?  Every Klingon knows what a {peb’ot} or a {Hurgh} is!  But what in the world is a {‘epIl} or a {banan}?

There is a long tradition in Star Trek of naming an alien thing with an alien name and then a common word to ground the viewer.

Moba fruit

Chee'lash fruit

Lokar bean

And so on.

Okrand is doing the same thing.
