My husband has cancer and could not receive his chemo treatments regularly because his platelet would drop too low. My brother told me about papaya leaf extract and we tried it. Within 8 days, his platelet count rose from 76 to 187. After 3 months of missing multiple treatments, he was able to complete chemotherapy. But after missing so many weeks of treatment, the outcome was poor, so now, on this second round, he is able to maintain a weekly regimen with the papaya leaf extract daily.
