Cayenne brings herbal heat to wherever you apply it, thus cayenne extract is a wonderful topical remedy for arthritis. For kidneys? I doubt it. kidney stones
are calcium, don't see how cayenne would have an effect on that. People who have too much yin (cold) action in their diet and lives may need things that are yang (heating) to balance their kidneys, but Cayenne isn't on the list. Cloves, ginger and cinnamon are.
The liver/gallstone flush and herbs that dissolve stones will help the kidneys, because the calcium stones form in the kidney because the gallstone is so overloaded. This causes an imbalance in the blood levels and weakens the kidneys, which then retains too much fluid and waste products and calcium until crystals form.
I'd recommend Gold Coin Grass over Cayenne pepper anyday. If Cayenne pepper were a cure-all, then people with hot spicy cuisine would never get sick - and they do!
