This means that the only way to get blood leaf tea is by harvesting it from the wild, a dangerous job even in my old life and my past world didn't have magical monsters roaming the wilds, and I haven't even mentioned the last piece to this puzzle, the magical effect of the tea doesn't give you magic but specifically increases one ability to regenerate their magic so while the effect doesn't do much for your average pony as they haven't trained to regenerate their magic, but for ponies that have the effect it is much more noticeable in some cases taking hours off recovery times.
