Salmonella bacteria, the major culprit in food poisoning, has been shown to be killed by neem extracts (Patel, 1962, 1965).
Although prevention is the best way to avoid food poisoning, once it has been ingested, neem is a viable option for reducing the length and severity of the attack.
Oral doses of neem leaf teas or capsules will soothe the upset stomach, help the body rid itself of the bacteria and provide relief from many of the miserable symptoms.
