I’m so sorry you’re suffering with LS… Need Oil is different than Balsam Peru, Castor Oil. I use a USDA/Organic Cold Pressed Pure Neem Oil I bought on Amazon. You should be able to find it or order it at a Health Store.
I have used Clobetasol Propionate Ointment and Cream but it wasn’t very helpful. But everyone is different and responds differently to treatments. I sincerely hope you can find Neem Oil and that the mixture with Green Tea Extract will help you.
