Hi Vanessa--
She uses lavendar and 'aches and pains' from a company called Wyndmere. She also uses the brand Aura Cacia. These brands aren't special in any way other than they are what we have at our local food co-op. I am guessing any health food store etc would carry some sort of essential oil. I know in our area, home sales of essential oils are popular too. I will have her post some websites she uses to mix and match them.
