how to make moringa powder at home - #23942

I am really curious about how to make moringa powder at home. I've read so much about its benefits and even started including moringa in my diet. Found some dried leaves at the local store, but they are super pricey! I have a garden where I've been growing moringa for a while now (even tho not that well, honestly), and want to try this out. Yesterday I harvested a bunch of leaves, and I'm just like, what do I do next? Do I need to wash them or just dry them right away? I hear people say that drying is super important for quality, and I'm worried about getting that part right. I left some leaves in the sun and others in the shade because I wasn't sure what’s best. And then, how do I actually grind them? I don’t have a fancy blender or anything, so just a regular coffee grinder would that work? Also, how long can the powder be stored? Like, do I need to keep it in the fridge or something? Any tips on how to make moringa powder at home, would be super appreciated!!! Thank you!!
