All this accumulates into its absurd price now as for why this is important is because I might be the only pony in Equestria that can produce as much as I like only requiring time as it takes longer to dry the tea than grow them, now I don't want to start selling the stuff as that would immediately put me in the public spotlight, but I can send a twenty-pound package of the tea to her, as for the reason I think she'll need it is that even if she wanted to drink it every day she couldn't because even though she definitely has the money to pay for it there's just not enough to go around, plus, the magical effect is still coming from the herb itself so for somepony of Celestia's size she'd need much more to achieve the same results.
