I heard that honey can became toxic, or dangerous to consumption after was heated to a higher temperature(above 40 degrees Celsius). For example, when you are preparing a tea is not indicated to put honey right away, when the water is almost boiling, because it may eliminate a toxic substance for human body.

IIs that true or ...

Another question that I have is that if it's Ok to give honey to a child that is almost 1 and a half year old?

Thank you a lot,
