I know the feeling! Especially when it comes to crystals- not being an expert with them, I try not to get any of mine wet unless I know 100% they are okay in water (like amber, which literally washes up on the beaches- if that’s not sea safe, I don’t know what is lol).
(Speaking of, there’s a handy list of some that should not go in water here: Crystal Safety- sharing in case it’s helpful for someone else too)
As for herbs, most of the general kitchen herbs (aka the ones you’d find in your spice cabinet) are fine in water- but you do have to be careful with sensitive skin.
Have you experimented with chamomile and calendula yet, @chelsie3? Those are both fantastic herbs for those with sensitive skin- both are gentle and healing 
Blessed be!
