The Langsat or Lanzones are originally from West Malaysia and became quite popular in Borneo, Java and in the Philippines. The lanzones comes in clusters of yellowish beige colored fruits. The fruit is segmented, fleshy and juicy when ripe. It may be seedless but would normally bear at least one very bitter seed. It is one of the best fruits to take to stop diarrhea.
The flesh of the fruit contains glucose, fructose and sucrose. It has antioxidant properties and packed with Vitamin A, C and E. For every 100gm consumed it yields enough protein, carbohydrates, calcium, phosphorous, beta carotene (Vitamin A) and dietary fiber. It also contains thiamine, riboflavin and phytin as well.
Eating lanzones is quite tricky. You must be careful not to bite into the seed because it is bitter. Opening the fruit lets out the sap or latex on the skin. This is a white sticky substance that tastes bitter as well. Other benefits from the fruit include burning of the dried peelings can repel mosquitos, ground seeds mixed with water can help purge intestinal worms and as a febrifuge.
