Review Nux Vomica has been my savior. I always take it along when I travel. It's a very versatile medicine. I have also taken it when I have felt my first recognizable flu symptoms--at the very beggining-- and it has really cut it off. It's just amazing. In addition, Boiron is a very well reputed lab for homeopathic medicine; I have found it available in many cities around the world.
