Unbalanced gut flora is one digestive condition associated with diarrhea. Some friendly bacteria numbers are in excess while some are lower than normal. In cases of food poisoning and other gut infections, pathogenic microbes alter the normal microbiota residing in the digestive tract.

Probiotic supplements can help balance gut flora and eliminate diarrhea and other symptoms. Researchers have studied probiotics extensively for diarrhea prevention and relief. They have especially focused on acute cases in children. Some studies found probiotics beneficial in these cases.

Lactobacillus GG and Bifidobacterium lactis, which you can combine with Streptococcus thermophilus can help. Other useful probiotics include:

  • L. reuteri
  • L. rhamnosus (not GG)
  • Streptococcus spp
  • L. acidophilus
  • Bifidobacterium ssp
  • L. casei
  • Saccharomyces boulardii (yeast)

These probiotics can prevent diarrhea associated with antibiotic drugs. Lactobacillus GG and S. boulardii are particularly helpful in managing infectious diarrhea. They’ve proven very effective with rotavirus infections.

Activated Charcoal

Activated charcoal is a powerful natural compound. It has a long history of use in medicine as an antidote for many toxins and poisons. Hospitals still use it for drug overdoses of aspirin, acetaminophen, and sedatives.

Activated charcoal can attract and expel toxins from the digestive tract. It also prevents the body from absorbing these toxins. The supplement has a negative electrical charge. So, it effectively traps various toxins and gasses with positive charges. Once trapped, the activated charcoal carries them out from the body in feces.
