No, you've more chance of walking to the moon in your bare feet.
If you ate the entire worlds supply of St Johns wort (i believe it was on his prick) and black pepper you still wouldn't activate oral DMT. You need moclobemide (trade name aurorix).
most "natural MAOIs" are triflingly weak, the only 2 that work to activate oral DMT I know of are B.caapi and friends (ayahuasca vines), and syrian rue.
And of course lots of people use pharmaceutical MAOIs too.
