Or HaChaim on Leviticus 19:26/אור החיים על ויקרא י״ט:כ״ו

1 לא תאכלו על הדם, "You shall not eat with the blood;" Bereshit Rabbah 21,7 say that the reason that this commandment appears next to the prohibition of ערלה is an allusion to Adam who had eaten from the tree of knowledge before its period of being ערלה had expired. [the other trees had been expressly permitted by G'd so that that prohibiton was overridden. Ed] According to the Midrash, all Adam had to do was to wait until the advent of the Sabbath. He would have been permitted to recite the benediction over wine; [according to the view that the fruit of the tree of knowledge were grapes. Ed.] This is the mystical dimension of the statement in Sanhedrin 38 that אדם מושך בערלתו היה, that "Adam was pulling at his ערלה." The word refers to the as yet not permitted fruit; Adam was too impatient. This is why the Torah writes next to the commandment וערלתם ערלתו, "do not eat with the blood," i.e. "do not eat of the fruit of the tree which is still ערלה because of the blood," i.e. all bloodshed in the world originated when Adam ate from that tree prematurely. We may extrapolate from this that had it not been for Adam's failure at the time there never would have been such a prohibition as the one described in our paragraph. Neither plants nor animals would have become restricted to man at all, either temporarily or permanently.
