ONION is a POWERFUL Antibiotic, Anti-inflammatory agent..
Make Sure you eat Cut onion The Same day (!). Some time back I posted an information here that CUT onion should NOT be used the next day due to the fact it becomes Poisonous and creates Toxic bacteria, even for the single night, which May Cause adverse stomach infections because of excess bile secretions and even Food poisoning.. I heard this information from other couple of sources too. Though I added chopped raw onion in my home made mustard (it seems like it was ok) but STILL just Try to Watch This Bit coz you never know How this Affects your stomach and all digestive system (!).
Raw Onion is Good for Candida Infections too.
In order to suppress raw onion after taste (breath), eat after that Raw Parsley. Should help.
