Distribution of the population of tongkat Ali (Eurycoma Spp.) in Malaysia based on data taken from herbarium records

Eurycoma spp., also known locally as Tongkat Ali is considered the most popular medicinal plant in Malaysia. The tremendous attention put to it by the public for its medicinal properties has led to its non-selective harvesting at a very alarming rate. Concerted efforts by a number of institution...
