This information provides support for the idea that humic substances (fulvic acids) are a
little-known and important missing link throughout the food chain. Modern agricultural
practices have eliminated the humic substances from farm soil, which parallels
increases in viral plant, animal, and human viral infections. Common to rich organic soil
humus, fulvic acids have been shown to have unequalled value in defending plants,
animals, and man against viruses of all kinds, and also in significantly increasing and
balancing immunity. Of interest is also the fact that hospital studies in China showed
that children with serious respiratory infections responded exceptionally well to humic -fulvic extracts when nothing else seemed to work.
