I had tried on the lips, genital and tailbone. It only suppressed herpes from coming out for one day or so. I think the smell is good, but my boyfriend with no herpes was still not used to the smell. One friend told me to use Hydrogen Peroxide 3 % on the mouth instead, and I tried, still Hydrogen Peroxide stops herpes for 3 or 4 days and not H-Balm. At those time, I used H-Balm and Hydrogen Peroxide for stopping outbreak when there is only tiny sore, and not wait till it came out.
