Chicken pox relief (preferably natural)?

My poor 11 year old sister got a really bad case of the chicken pox 2 days ago, 2 weeks after my little brother had it :( they were *not* vaccinated (I was) because.... I have no clue, ask my parents, so no crap about that plz. So, I've heard baths in oatmeal and baking soda help, teas, soups, and some freaky herb combos =P so could i just get some ingredients or recipes or just some advice and that'd be all thanks so much everyone, God bless
