Protein profiling of Orthosiphon stamineus
Orthosiphon stamineus (cat whiskers) is a medicinal herb belonging to the family of Lamiaceae, where the leaves are commonly used as herbal tea known as “Java tea”. It is used as a diuretic agent and for the treatment of heat rheumatism. Currently there is no protein profile data available for this...
