逻辑: 1. Patent: Research can test on effectiveness on medication. Those medicine with patent will have high market profits. Chinese herbal can hardly have patent so it cant have high profits( or it can be used widely...). Now government should give more funds to herbal medicine research. Ask for assumption. What i chose is: Physicians intend to choose medicine with approved effectiveness. (or with patent...)
