I want to try the hydrogen peroxide wash for the BV that I have been dealing with for almost a year now. My question is - I bought the 3% Hydrogen Peroxide H2O2. I keep reading on the internet that you should use the 3% FOOD GRADE for douching. Did I buy the right stuff? The stuff I bought doesn't say anything about Food Grade on it. I'm anxious to try this...can someone please help?
