You have to soak them and getting the seeds out is a little tedious. I picked a bunch a few years ago for the same reason (vit c) and they were full of larvae. It looked like little maggots all over the pan they were in. I guess the bugs lay eggs in them. I ended up tossing them. They're definitely packed with vitamin C though. I got familiar with the plants around here and their uses. They are very potent. 6 years ago, or so, all of a sudden I became allergic to mosquitoes, the bites send me to the ER but if I find yarrow or broad leaf plantain fast enough and apply it , the bites disappear within a minute. There is food n medicine everywhere. The plant kingdom is truly amazing. God is awesome.
