I did when you posted the study time ago, but stopped it because I was afraid of my liver. I took 300 mg 3 times a day around 3 weeks. Don't know if it affected my liver but I stopped it anyway. I was also taking other things at that time. I have been thinking from more than one year to try turpentine. I have a lot papers to read about, but have never done it. Niacinamide is probably effective the liver is my concern.
Good Luck,
Jorge.
