To break down internal scarring, soak a piece of clean cloth with castor oil and place it over the scar area for an hour or two each day. You can also simply rub castor oil over the scar each day. More serious internal scarring will take longer to break down.
On another note, castor oil can also prevent scars from forming in the first place. Applying castor oil over cuts or scrapes will promote excellent skin healing.
Remarkably, applying castor oil after surgery, cuts or wounds will also minimize scar formation. This could be because of castor oil’s ability to increase our body’s lymphocytes (because of this, castor oil packs are especially useful for people with HIV or AIDS). Lymphocytes, or white blood cells, appear to regulate wound healing. And studies have shown that T lymphocytes may play an important role in wound healing and scar formation. Babies and young children have naturally higher levels of lymphocytes than teenagers and adults, which could be one of the reasons why our skin healed with much less scarring when we were younger.
