Taboo: don't drink strong tea during taking medicine, try to eat less spicy and greasy things, and avoid eating tobacco, alcohol and coffee.
Beware of counterfeiting: Since May 2006, the original outer box has been labeled with goose egg-shaped high-tech secret code anti-counterfeiting labels, and it has been changed into a new high-tech secret code anti-counterfeiting label with oval wavy edges.
Note: Hongyun Hi-Tech's secret code anti-counterfeiting label is disposable, with China and Hongkong trademark registration numbers on the surface. If the surface film is torn off, the words genuine will appear.
