Hibiscus tea with lemon and ginger is a caffeine-free infusion of hibiscus (roselle) calyces flavoured with lemon and ginger; hibiscus has some of the better evidence among herbal drinks, with small trials showing modest blood pressure reductions, by several mmHg in some studies. Most trials lasted 2–12 weeks and used unsweetened tea.

- Blood pressure: modest effects in small trials; not a treatment.
