Have this product gift of my friend who is plagued repeatedly by this pesky virus. If she has deep cleaned the cat premises or scratched old glued carpeting from the floor or just too much was in the sun, caught the upper lip to ache and shortly thereafter the not nice to be regarded bumps that then burst open and they tormented mind. 1 week emerged have. Long story short: Since then I have given her the pin, she has had no outbreak or busted bumps! Once a first tweet is palpable, the pen is regularly applied and is good! The first time, the viruses have then moved into the nasal cavity, this has then (my) Manuka Honey used and simply applied to the mucous membranes. The honey also helps great if it has already broken out, which relieves pain very strong! All good :-)
Addendum 29.10.2014: The same pin (bought on 03.09.2013) is still in use, a great spreading rate, the value for money is therefore great.
