Castor oil packs can be used to treat everything from uterine fibroids to PMS. I have been using them recently, but have stopped. I did not stop because I didn't think this was working, rather, because I just can't bear to do it anymore. Here are the steps I had to take:
1) soak wool cloth in castor oil
2) put wool cloth on stomach (if it was a pre-soaked wool cloth, I would pull it from the fridge and put it on -- yikes!)
3) wrap stomach in saran wrap (no, I am not kidding here -- it is to keep the castor oil pack in one place and to ensure the oil did not get on my clothes)
4) lay with a heating pad on stomach for 30-45 mins.
5) take off pad, wrap and castor oil pack
6) make water & baking soda mix, dip towel in mix, wipe off extra castor oil from stomach with wipe (this kinda works, in my opinion)
So, after reading this, you probably have a better idea as to why I may not do this anymore. I cannot speak to whether or not this worked for me. My PMS symptoms were dramatically less after doing this, but I was also doing other detox tasks during the time I was doing this.
