Well, the experts which were consulted by the writer of the article have this to say:
> I had a breakthrough a few months later when I came across a thesis paper by Dr. MS Rathore, who had propagated Maerua oblongifolia in the lab in 2011. He had seen the tree many times in the desert state of Rajasthan. “But I haven’t heard or seen anybody eating the root,” the scientist said over a call, sounding puzzled.
> “Its roots are sparse and inedible,” added Dr. NS Shekhawat, his thesis adviser and a retired professor of botany. “Growing in dry regions, where will it have so much water to develop big roots and be fat and juicy? [The snack] can’t be Maerua oblongifolia.”
Which seems to provide a little bit of a counterpoint.
