Natural Cures for Angina (Chest Pain)

My mom had pneumonia for over two weeks, all drugs FAILED. I put pharmaceutical grade Tea Tree oil (antimicrobial) in a diffuser and her lungs cleared up IN 1 HOUR! I'm here to take notes on the Angina. Thank you everyone for sharing your stories! ALSO another thing to help Lung infections or Congestion is Mullein! It's a flower. I bought tinctures and a few drops under the tongue work almost immediately!!
