Introduction
Currently it is becoming more common to consume drugs with medicinal herbs, and studies that evaluate the potential or possible interactions of therapeutic drugs and herbal medicines are therefore much needed. In Malaysia, two of the most commonly used medicinal herbs are Andrographis Paniculata and Orthosiphon Stamineus.
Andrographis paniculata (Burm. F.) Nees from the Acanthaceae family, indigenous to China, India and South East Asia has been traditionally used in Asia for gastric disorders, colds, influenza and other infectious diseases[1]. For the last two decades, a standardized extract of Andrographis paniculata has become popular in Scandinavia in treating the common cold [2]. There are also reports on
Andrographis paniculata’s effectiveness as an immunostimulant [3] and as an anti-HIV drug.
