I started getting heart palpitations every day for the last month or two. They are very scary. I was told to cough hard to get the heart back in rhythm. That worked for a second or two. I then took Black Strap Molasses (1 teaspoon) and a 1/2 hour later I drank water with 1 teaspoon of Apple Cider Vinegar. That combo usually stops the palpitations for 1/2 a day.
HOWEVER, I started OP (Oil Pulling) every morning on an empty stomach (1 teaspoon of either virgin olive oil or 1 teaspoon of sunflower oil) and since I've started, I've had no palpitations at all! It's amazing!
If you want to try this, please read up on it (on this website) first.
