6. Cayenne Pepper
This is often seen as a spice of red or brownish color and is very popular in many parts of the world as a flavoring for food. Cayenne pepper is quite hot, both in its natural fruit form and as a spice. Due to this reason, it is most often eaten in very small quantities. So, even though it contains a high amount of various vitamins and other beneficial components it has very little effect when consumed in the regular amount you would commonly find in food.
Cayenne pepper can provide a natural alternative to blood-thinning prescription medications, but it is important to talk with your doctor before changing any of your habits. And, as mentioned above, any benefits from cayenne pepper will most likely only be seen when taking it in the form of a supplement. This will also eliminate most or all of the spicy heat you would get from either the dried powder or fresh fruit of the plant.
