Query: DO NOT BUY THIS

AOS is notorious for overcharging for their products. it is simply castor oil, olive oil and essential oil fragrance. the best mix is 2:1 castor to olive oil. you can throw in another :1 of canola oil if you like. you'll need a bit of EO to mask the slight scent if you don't like the oil scent. this can be bought for about $10 a bottle on ebay or a local health store and it will last a long time.
