Coughing out blood - While using Essiac Tea

Hello folks,

I recently added Essiac tea to my arsenals against my Breast Cancer that metastasized to my left lung. It has been 4 days of taking 30ml of Essiac tea in the morning and before I go to bed. This morning when I awoke to brush my teeth. I can't stop coughing. I would cough occasionally but not as bad as I did this morning. I spate out blood because of the harshness of my coughs. If I were to measure the blood in a cup i think I could have filled it. I was wondering if there was anyone who has any similar experience as I have? Is this a good sign or should I be troubled?

I also read that taheebo would have the same results because the tumor wants to remove itself from your body. I didn't have this result with taheebo but I did have it with Essiac this morning.
