I wrote a blog post last year discussing my personal experiences with Atrial Fibrillation. Surprisingly, 1172 people downloaded that post and it became my fourth most popular post of all time. I hadn't thought of how many people share this malady.
As I understand the Wise Woman tradition, nourishment is one of the key concepts, so before we even look at a specific situation like Atrial Fibrillation, let's look simply at nourishing the heart.
I figured needed to rebuild my circuitry, and I needed to withdraw from the world for a while. To lessen the stimuli, I spent a lot of time in the dark, avoiding man-made light, and a lot of time in bed. I had an old cat named Lady as my constant companion, and I don't think I could have made it though the downtime without her.
Additionally, I see the heart and any maladies thereof as connected to every other organ and system of the body, again, in this case, the nervous system is of prime importance.
Nourishing kidneys and lungs is also very important. Stinging Nettle infusion is the supreme kidney ally, and Nettle also strengthens the lungs, along with the blood-building herb Red Clover; they are a powerful combination to alternate--one day Red Clover infusion and the next day Stinging Nettle infusion.
