Is rubbing raw garlic on chicken pox effective?

I really need to do something about my chicken pox. I want to go to the party tomorrow. My chicken pox are starting to dry but they are still reddish-violet patches. I couldn't order anything from the internet now because it takes 2-3 days to be shipped.. I saw some articles in the internet saying that rubbing raw garlic can fasten up drying and prevent scars. Is it true? And when should I rub it? day or night? And should I start now? When the condition of my chicken pox are like these?
