Congenital Heart Defect

I have a serious congenital heart defect with high pulmonary hypertension and because my blood thickens due to this defect, I have to go for venepunctures from time to time. Three years ago, I had to undergo a very difficult surgery for peritonitis because due to a doctor's misdiagnosis, my kidney abscess burst; he had diagnosed cancer. Even after that surgery, I felt quite well for a while, considering my state of health. But recently I have been constantly exhausted, tired, and I tell myself that things aren't going to be very good with my heart anymore. Nevertheless, I don't give up, I'm not a fan of sitting around at doctors' offices, and I often turn to various herbs. For example, I lowered my cholesterol with speedwell, every morning on an empty stomach I drink apple cider vinegar, etc. For my heart, I only take 1 Digoxin tablet. I would like to try your preparation to see if it would put me back on my feet for a while, I'm just afraid of a negative reaction, so that I don't attribute it to a worsening of my heart condition. Do you think I could take it? Thank you.
