I am definitely surprised at how effective this is. I purchased this after a desperate search for some alternative medicine to help with Psoriasis, and this was mentioned as part of a liver cleanse. It's far too early to tell if it is helping with my skin, but I am also lactose intolerant, and typically I consume ginger in tea every day to mitigate the sensitivity. Lately, however, that has been getting less effective, and symptoms have been getting worse, to the point I was about to go see a doctor to see if something else was wrong, as I was consuming almost no dairy. However, about a week after I started taking this daily, all symptoms are gone! I take about an 1/8th ounce twice daily. The taste is certainly not pleasant, but it's not as bad as I expected from some of the reviews. I will definitely be buying the larger bottle and adding it to my regular routine, now
