Numerous phytochemicals with biological activity have been identified. In modern medicine around a quarter of the drugs prescribed to patients are derived from medicinal plants after clinical trials in animals and human subjects for efficacy and side effects. Some of the findings have led to the production of plant-based medicines. The global market value of medicinal plant products exceeds $100 billion per annum.

In some Asian and African countries up to 80% of the population relies on traditional medicine for their Primary health care needs. Hence countries like China India have combined traditional and modern medicine in the health services.
