The roselle species can be grown commercially, as a perennial, in hot tropical areas, or as an annual in colder climates. Hibiscus tea is produced only from certain cultivars or varieties of Hibiscus sabdariffa; other cultivars of this plant are used to produce fiber, or for ornamental purposes such as landscaping and gardening.
Hibiscus is also one of the most common ingredients in herbal blends; it even occurs as the main ingredient in many herbal blends widely available in supermarkets in the U.S. Hibiscus is rather acidic, and its most common use in blends is to impart a sour taste and dark red or purple color, although it also imparts aroma as well.
A drink of many names:

In some regions, hibiscus is also blended with black tea.
Medicinal uses and health benefits of hibiscus tea:hypertension (high blood pressure), lower fever, and treat liver disorders. Hibiscus is also rich in vitamin C and other antioxidants.
A human study has validated that hibiscus tea, in an amount easily incorporated into the diet, is effective at lowering blood pressure in people suffering from hypertension. The extract of the hibiscus sabdariffa plant has been studied more extensively and compared to various drugs used to lower blood pressure: it was found in a 2004 study to be roughly comparable in effect and tolerability to captopril, and a 2007 study found it to be less effective than lisinopril, but it showed 100% tolerability (absence of intense side effects) in this study. It is likely that hibiscus acts to lower blood pressure through being an ACE inhibitor.
There is evidence both from studies on rats and rabbits, and more recently, human studies, that hibiscus sabdariffa can lower cholesterol levels.
Studies in mice and rats have also validated that hibiscus has a fever-lowering (antipyretic) effect, and the evidence suggests that the mechanism by which it acts is different from that of aspirin.
A study in mice found that hibiscus sabdariffa can prevent liver damage caused by acetaminophen, the active ingredient in Tylenol and a number of other pain-killers, which is known to cause liver damage in high enough doses.
