Question About Disposing/Re-using Spell Components

I did a luck spell in a little fabric bag that I carried in my pocket during finals, and I've just realized that I didn't do anything to dispose it. I used a whole nutmeg in that spell, and it seems like it'd be a waste to discard it, and I'm also anxious about burying it because I have a dog that really likes to dig and don't want him to find it as I've heard it can be fatal for them.

I looked online but people seem conflicted about whether or not you can reuse ingredients. If I do reuse the nutmeg, should I do something to cleanse it?
