You can take aloe capsules or guide tablets, about 4 capsules each time, which can help you have diarrhea. Of course, if you don't eat them, you won't have diarrhea.

The side effects of drugs that can cause fever are too great, so don't eat them! ! !

I checked, and most of the drugs that cause fever can cause more side effects, such as coma and organ failure, so I can't provide them for you.

If you really want to have a fever, another good way is to take a cold shower in the morning. This doesn't cost money, and the chances of success are quite high!
