You can eat it, but because Radix Isatidis has a strong taste, I suggest you crush a tablet of medicine and add it to water. Put a quarter of it in a pot of water. Don't add too much. Rats will not drink it because it smells too strong. You can also add a little glucose to the water. You can observe the change of water quantity. If the water quantity decreases rapidly, you should add more water and less medicine and sugar, although rats and mice are fragile. Coupled with your own immunity, your metabolism is very fast. Therefore, sugar and drugs stay in your body for a short time (usually half a day). Therefore, increasing the number of times is the key to treating hamster diseases. The above is personal experience and I hope it will help you.
