Nirvana - Pennyroyal Tea Lyrics Meaning

First off, Pennyroyal tea is a drink that is high in iron, and has a reputation for basically at home abortions.

I'm on my time with everyone- I feel like I'm gonna die soon.
I have very bad posture- Kurt had bad posture because of a problem he had with his back.

Sit and drink Penny royal tea,distill the life that's inside of me- this is NOT about abortion.the 'life inside of me" is like a second half.
sit and drink Penny royal tea, I'm anemic royalty- Penny royal tea being high in iron would help with anemia, it being an iron definciency in your blood.

he's obviously getting tired of himself, and just being who he is,not so much on the inside emotionally, but physically. In this song he talks about his bad posture, and his anemia. as you get farther through, he continues the verse and says:
Give me a Leonard Cohen after world, so I can sigh eternally- I guess this is a sorce of self pitty.
I'm so tired I can't sleep, I'm a liar and a theif-this goes back to where he says "distill the life that's inside of me" it's about being tired of himself, and being who he is, this deals more with what one side of him is, but he doesn't wnat to live up to it, and is getting tired of it, "distill the life that's INSIDE OF ME"

I'm on warm milk and laxatives, Cherry flavored antacids-this talks about his horrible stomach problems that he dealt with through the last five years of his life.this is basically about Kurt not wanting to deal with himself anymore.His inside problems, and his health problems.thats a basic way of putting it. This song is not at all about abortion.
