For Bronchitis:
According to research done in the University of Maryland Medical Center, probiotics are a great option for helping treat bronchitis. Probiotics are known to be a unique formulation of “good” bacteria. These bacteria help prevent infections by working in the digestive tract and supporting your immune system. You can take in probiotics in capsule form or find them in foods like yogurt.
For Diarrhea:
Probiotics are also known to help ease the symptoms of diarrhea. If your infant is experiencing this problem right now, breast milk should do the trick.
