this is the one product that has helped me the most for burning and pain!! Get the green bottle not the extract,works better. You can take up to 10 pills per day but just a few are all I need. I posted this on another site and guy said I changed his life!! No side effects however they say dont take if you have gallbladder problems. It als helps arthritus. Its cheap at around 9 cents per pill. Also relieves stomach upset.
