hi, I just want to ask--is it safe to uses indian almond leaves that have dried up, but are not sun-dried? What I mean is, I noticed that the leaves that naturally fall from the tree are usually sun-dried, meaning they're all brown and crispy. I got some leaves from the branches (still alive) about a month ago, they have dried, but are not totally brown as I did not lay them out in the sun. Is it safe to use them?
