I love spicy food! I put cayenne pepper on everything
I love spices too.  Now, some like herbs (leaves, flowers, or stems), but I am like you, I prefer the spices (seeds, fruit, root, or bark).  Other than cayenne pepper, what other spices do you enjoy?
I really love Dill! I love to put it on baked potatoes
I like the sweet potato myself.  I do like baked potatoes, too.  Anyway, sometimes the leaves and shoots of sweet potatoes are eaten as greens.  Have you ever eaten sweet potato?
Yes! I love to roast sweet potatoes with olive oil and different spices
Spices are great!  Not only for flavor, but also for their antimicrobial properties.  Spices are mainly grown in warmer climates; so I am thankful to have them in the colder climate where I live.  
I didn't now about antimicrobial properties of spices! That's good to know
Yes; sometimes spices are used in medicines.  Egyptians even used herbs and spices for mummification.  
Wow! That's pretty cool!
Nearly 1000 years before Christ (BCE), medical systems based upon herbs could be found in the Far East: China, Korea, and India.  The spice trade developed from them.
