Using Castor Oil Medicine to Treat a Wound or Speed Healing

• 1). Wash your hands with soap and water and dry them thoroughly. Treat a wound with castor oil only under a doctor's care. Your physician will prescribe the oil in gel or spray form, which you will apply to your skin.
  
  
• 2). If you are using a prescribed castor oil spray, prime the pump by pumping it repeatedly while holding it upright. Shake your bottle, hold it about a foot away from your skin, and pump to spray onto skin.
  
  
• 3). If you have a gel form of castor oil, open the tube. Apply a small, thin layer to your fingers, and then rub your fingers gently against the affected area. Wash your hands again when finished with the application..
  
  
• 4). Cover the area only if directed to by your doctor. Repeat the process as often as directed by your doctor.
  
  

Castor Oil Packs to Treat Muscle Soreness or Carpel Tunnel

• 1). Create a castor oil "pack" to treat sore muscles or to ease your carpel tunnel syndrome. For this purpose, you don't need a prescription. You can use the castor oil you'd find in your local supermarket. Dampen flannel cloth with castor oil, but don't saturate it to the point that it is dripping.
  
  
• 2). Cover your wrist or other affected area with the cloth, and then cover the cloth with a clean, dry plastic bag.
  
  
• 3). Apply a heating pad over the plastic for an hour. A University of Maryland Medical Center article recommends continuing this treatment at least twice daily and four nights a week until you see relief.
