Tamiflu (Oseltamivir), C16H28N2O4, is a drug that is used to treat influenza. The preparation of Tamiflu begins with the extraction of shikimic acid from the seedpods of the Chinese spice, star anise. From 2.6 g of star anise, 0.13 g of shikimic acid can be obtained and used to produce one capsule containing 75 mg of Tamiflu. The usual adult dosage for treatment of influenza is 75 mg of Tamiflu twice daily for 5 days. (2.7, 6.5, 7.2, 7.3, 7.4, 7.5)
