I have been taking 2 grams of Korean Ginseng for a few months now and have found no problem with interactions with use of Warfarin. I not here for experience here. I take mostly in the hope to achieve some energy improvements, none noted, but fyi, I lost about 10 pounds down from about 238, I am 6' 5". I believe this may be due to the Ginseng affect on my digestion of carbohydrates (which I love to eat) - causing less production of blood sugar and fat. I share and ask here for experience, reaction, any other inputs members care to share. I am considering stopping Ginseng to see if my weight goes back up, but an early test of cutting does in half seems to have resulted in me developing an increase in fatigue, a withdrawal side effect? I also note this cutback test has shown an increase in weight of about half the original loss. I went back on full does last Sunday.
