Floc it, really? Simply powder the seeds and filter your water through them.
If you haven't tried drumsticks, I recommend them. Quite delicious.
The plant is so tough it survives in near-deserts and so fast-growing that the pods can be harvested from plants grown as annuals. The leaf powder is an excellent protein source (now sold at ridiculous prices in health food stores in the developed countries) and most parts except for the wood can be eaten. It is prized wherever it is grown.
