As a cardiologist this is a very useful herb/spice. It helps blood to clot both internally and externally. It is a very warming herb, and most hear about it for it as a digestive aid. It also does support the immune system because it is rich in vitamins and minerals.
It is a supportive herb for cold and flu . It can be used as a tincture and given several times during the day to ease the sore throat. There are many herbs that I use instead, but cayenne has miraculous results
For those patients that suffer from cold hands and feet either due to thyroid issues or Raynaud’s I suggest using Cayenne . It increases the circulation I have seen an old man, age 88 sprinkle cayenne pepper in his socks ( the toes of the socks) for warming in the winter months
There are excellent remedies for Cayenne Pepper. The BEST book for remedies just released is “ The Lost Book of Remedies” by Claude Davis
