Why is Tamiflu so expensive? The raw materials are expensive. Still high technology.

Tamiflu is the exclusive production right of a Swiss factory. China does not have the right to use this patent. Import is the only way for China to obtain it. Usually, the price is 1 tablets in 4 yuan, and you can buy them from pharmaceutical companies above the municipal level. A small amount of raw materials are extracted from our star anise in China, which is 4 kilograms per 8 kilograms.
