According to a study published by "Tropical biomedicine", methanol leaf extracts of Podocarpus macrophyllus are used to examine effects on Cryptosporidium parvum in experimentally infected mice. Treatment with these extracts showed a significant reduction of the number of C. parvum oocysts shed in the stool compared to the infected control group and the Nitazoxanide-infected treated group at P < 0.001. Histopathological inspection of sections from the ileum and colon displayed signs of improvement after treatment with P. macrophyllus extracts. The study also involved spectrophotometric estimation of the total phenolic and flavonoid content of these extracts.
