USER: rephrase and rewrite the following article:
Paprika is believed to impart a wide variety of health benefits, ranging from the treatment of rheumatoid arthritis and osteoarthritis to anemia prevention and even fuller, softer, healthier hair. Not all of these purported benefits are supported by strong scientific evidence.

Some of the health benefits attributed to paprika are associated with the spice's capsaicin content. Capsaicin is a chemical found in many hot peppers and it gives the peppers their heat. Paprika that is made from spicier peppers, such as cayenne pepper or poblano peppers, will also contain capsaicin.

But not all peppers have capsaicin. Paprika made from red bell peppers, for example, will not provide capsaicin because the peppers do not contain the chemical.
