I have read articles on castor oil massage therapy for curvature reduction. Has anyone performed this procedure and if so what results did you experience?

To cure ED

This is the ED section of the forum.  Did you mean to cure Peyronies Disease?  If so, this should be in the Peyronies Disease section of the forum.

At any rate, I think it absurd to think castor oil is going through your skin and penetrating the tunica.  It is also absurd to think that if id that caster oil transforms scar tissue.  It should be easy to tell.  Find another scar on your body.  Document the size and visibility and rub castor oil on it and see if it fades or reduces.  If you cannot affect a surface scar with castor oil's direct application, how could it ever reduce scarring on the tunica by putting it on the skin?

There is some chance that regular massage with anything including motor or might reduce scar tissue or at least stretch and soften it.

I massage my penis with warm castor oil daily, what I noticed is that my erections are better, I don't know is because the heat or is the combination

Yes, you do know because anyone who does the slightest research knows Castor Oil does not penetrate the skin and go into the tunica.  They also know that even if it did that, it does not do anything to scar tissue.  So, you know that it might be heat, might be message, might be psychological, might be a spontaneous improvement, might be a coincidence and be from some change in your diet, or might be 20 other things but certainly not Caster Oil

I've tried castor oil massage for curvature reduction, but I have to say my results were disappointing. While castor oil is often promoted as a natural remedy with anti-inflammatory properties, there's very little scientific backing for its effectiveness in treating something as complex as penile curvature, especially in conditions like Peyronie's disease. The massage process might feel soothing temporarily, but the oil itself lacks the proven capability to alter fibrous tissue. In my experience, I noticed no real change, and dedicating time to such unverified methods can actually delay more effective treatments, like traction therapy or even medical intervention. Unfortunately, relying on castor oil could lead to false hope without delivering actual results...

Like others have already stated above, castor oil is useless for Peyronies Disease.

The only thing I find it good for is its moisturizing properties. Plus it is also beneficial in constipation.
