Winter Soursop

Pictures taken today from the waterlogged front lawn: two immature soursop fruit (Annona muricata) on a tree planted in the front bed just a year ago. This tree has grown quickly. Supposedly, when the fruit is mature it will yellow slightly and blur the lines defining segments around each spine in the rind.

Soursop is touted on the web for anti-cancer properties of a tea made from its leaves. Although a category of plant extracts classified as annonaceous acetogenins, which are found only in the soursop (graviola or guanabana) family of trees, do kill cancer cells in vitro (cell cultures in test tubes), there is no evidence beyond hearsay of anti-cancer properties in live humans. But the leaf tea and fruit are both tasty.
