Yes, first of all, when we have the "runs" , the body is trying to remove something unclean or poisonous from our bodies. Oftentimes, when a person does not have an appetite, then usually they have eaten or dranked something that has damaged their kidney and, or liver. I recommend that you first, buy a bottle of (charcoal capsules) you can find them at most health food stores. Charcoal will absorb all poisons , toxins and contaminates, except lead and mercury. Whenever a person feels ill or is suffering from headaches, the first thing that they should do is take 3 charcoal capsules. The pain or nausea usually goes away within 10 minutes. If this was caused by a fungus or virus, then you should purchase a bottle of (olive leaf) from wal-mart. Wal-mart brand has the highest quality olive leaf. Olive leaf kills most viruses and fungus. In fact, if a person takes olive leaf everyday, it will be hard for them to catch anything! Keep in mind, that diarrhea can dehydrate a person quickly; so you should make sure that your daughter is drinking plenty of fluids. I am familiar with many natural cures. Write back if this does not solve your issue quickly.
