Castor oil is known for its many healing qualities.   This soothing oil can also be used for sore muscles & joints, rheumatic joints, menstrual cramps, bowel cramps and more.
 
For larger areas: Using a heavy cotton cloth, apply a generous amount to the cloth and apply to the area affected.  Then using either a belt, strap or even cling wrap to hold in place, allow the oil damped cloth to rest against the affected area for several hours, while relaxing and enjoying some down time.  Maybe even take a nap.
 
For smaller areas such as moles, skin tags, dark spots, damaged & altered skin: pour a dime to quarter sized amount of oil into the palm of the hand (depending upon size needed to be covered, then rub into affected area.  You may wish to cover the area with a bandage or cotton cloth.  Daily or even several times daily can increase the effectiveness of the oil.
 
Castor oil can stain, please use caution with all materials.   You may wish to keep this oil away from any materials that you don't want it to penetrate into.  Best to use old clothes, cloths or keep the area covered so as not to stain your good clothes or home goods.
