Cayenne pepper helped me somewhat, for arrythmia. But then, after a while, joint pain and tendinitis kicked in. The cayenne pepper sensitized me to nightshades and now I can no longer eat tomatoes, potatoes, peppers etc. So, while cayenne helped a little, in the long run I have nightshades to add to my long list of allergens. What did help me was to get off of a vegan diet and eat meat again. At least it helped me for a year or so. Now, the arrythmia is back again. Sigh!
