Thanks for reminding me. I tried eating the, but it was hard to eat more than a very few. I think I'd have to find a way to eat them by mixing them with something more palatable.
I've read something before, indicating you shouldn't eat very many of them at a time. I don't think that's a problem for most of us :)

"The black seeds of papaya have been found beneficial in the treatment of cirrhosis of the liver, caused by alcoholism and malnutrition. A tablespoon of juice obtained by grinding the seeds, mixed with ten drops of fresh lime juice, should be given once or twice daily for about a month as a medicine for this disease."
