An In Depth Look at Natural Skincare. I remember as a child my grandmother putting a castor pack on my stomach to sooth a belly ache. Until this last year, I never really thought castor oil was good for much. At least not until I came across the oil cleansing method. I started off mixing it with other oils, and ended up using it on its own. I love the viscosity of the oil, it feels like it is really cleansing deep into my pores. The same thing can be done.
