How dry is dry?

Checked on the purple deadnettle I hung up to dry this morning, and it's hard to say if they're dry enough or not. The leaves are indeed dry, but they don't crumble in my hand, so I remember reading they should. Another day or so?

Blame oatstraw?

I was feeling like I needed something light, calming, and nutritive, so I made myself some oatstraw and camomile tea before bed. What followed was an overwhelming drying sensation in my throat--I was completely parched! Even the next day, glass after glass of water could not satisfy this overwhelming thirst. Herbs, body, what are you telling me?
