Recipes for natural bug repellent and sooting ointment...?

[Loraxp]

Well, I found this on another site and thought someone might be able to help me figure something out...

Bug dope -
5.5 tsp citronella oil
1 drop liquid soap
4 tsp camphor
4 tbsp mineral oil
0.75 cup ethyl rubbing alcohol

*apply sparingly*

Question - what the heck is camphor???????!

I still am in need of a soothing ointment recipe (or any other recipie for bug spray). The dog has reacted badly to the bites it has already recieved (mosquito and *black fly*).

Thanks!!
