Orthosiphon (Cat's Whiskers, Java Tea) and Blood Pressure

What is Orthosiphon? Is it a any kind of stimulant that would raise blood pressure?

The Orthosiphons are little known members of the mint family. One species, Orthosiphon aristatus (syn. O. stamineus), is a medicinal plant from South East Asia. It has several common names: cat's whiskers, java tea, and kidney tea.
According to several reports, O. aristatus does not raise blood pressure, it lowers it. There is a list of recent reports at www.newcrops.uq.edu.au/listing/orthosiphonaristatus.htm. Check Medline for more recent reports.
