It won't produce toxic substances! It's just a great loss of nutrients! But harmless to the human body! Remember to drink honey water when the water temperature is around 60! Drink real honey! You won't lose money if you insist on drinking honey water for one day! The honey in Hebei Kang is good! I've been drinking his Sophora japonica honey! It tastes really pure!
