Fold piece of flannel to size of abdomen. Lay in a glass bowl or shallow dish. Pour about 2 tbsp. of castor oil over – just enough to saturate (should feel like suede).

Get your hot water bottle or heating pad ready.

Place your towel on a flat surface like a couch, your bed, or the floor.

Once you lie down, place your saturated flannel over the affected area of your body.

Cover the pack with an old thin towel (to protect staining heating pad).

Place the hot water bottle over the pack and let it sit for at least 45 to 60 minutes. During this time, you can rest or read a book.

When the time is up, remove the pack and clean the area with water and a bit of baking soda if needed.

Keep castor pack in a glass mason jar for next use. Apply more castor oil as needed.
