What Are Effects Of Using Antoxid For Recurring Mouth Ulcers?

Hello doc.I have been having regular and consistant mouth ulcers in various parts of my mouth and tounge. These ulcers would often take 4 to 5 weeks to heal and then the next ulcer will start after a few weeks again. Most routine treatments failed. But, Since I ve been having antoxid capsules, my ulcers heal very quickly and they do noy grow big.Why is this happening ? What is Antoxid for?Can I continue taking antoxid regularly? Any side effects or risks ?ThanksKrishna
