A castor oil pack can help with a variety of ailments like constipation, pms, detoxification, inflammation.
You are going to need castor oil which is available at any health food store, a piece of white fabric, a plastic bag and a heating pad.
Apply a 3-5 of tablespoons of castor oil to your fabric.  Place the fabric in the microwave 5-7 seconds.

For an abdominal castor pack place the fabric on your abdominal area under your ribcage right down to your pelvic bones. Then place the plastic over top and then apply your heat. Rest for at least 30 minutes. Once you take it off if, put the castor oil on the fabric into the fridge. When you take it out of the fridge for your next use go through all of the same steps and apply more castor oil each time. I recommend a castor treatment 2-3 times per week.
