Papaya seeds contain numerous bioactive compounds capable of killing parasites. The most prominent among these is referred to as carpain. It is a natural compound proven to kill intestinal worms and amoebas by paralyzing them. Papaya seeds also contain an enzyme called papain, capable of breaking down proteins. This comes in handy while softening and destroying parasite eggs that are most likely to be hidden in the gut.
In addition to these compounds, papaya seeds also have traces of benzyl isothiocyanate. It has been discovered to have antimicrobial as well as antiparasitic action. In a Nigerian study, pediatric patients treated with papaya seed extract showed a spectacular reduction in intestinal parasites. Not only was the treatment efficacious, but it was also safe, and no side effects were reported.
