Arabinex contains arabinogalactan, a naturally occurring polysaccharide extracted from the larch tree. Arabinex is a fantastic immune booster that I recommend taking at the first sign of a cold or flu. Arabinogalactans ares long densely branched high molecular weight polysaccharides similar to those in Echinacea and therapeutic mushrooms. It is immune stimulating and extremely useful in acute viral infections. Arabinex's water solubility makes it an excellent choice for pediatric use - it dissolves easily into water into a clear, almost tasteless liquid. Each rounded tablespoon contains: Arabinogalactans 4.7 grams
