This paper is absurd. What possible reason could there be to show that a dose 10,000+ times the normal dose is toxic? Isn't that a given with all known substances? I fear many people would read the abstract or even just the title and conclude that Hibiscus sabdariffa, which is incredibly safe, is dangerous, while in fact this paper supports just how safe it is (when given in reasonable amounts).
