BACKGROUND: The purpose of this research was to determine the acute and subacute safety and proof-of-concept efficacy of carbohydrate-derived fulvic acid (CHD-FA).
METHODS: In this double-blind study, 30 male volunteers with predetermined atopy were randomly assigned to either Group A or Group B, each consisting of 15 participants. In part 1 of
the study, the groups were administered increasing amounts of CHD-FA, ranging from 5 mL to
40 mL, provided that no adverse events had occurred at the previous dosage. In part 2, Group A
participants received 20 mL of 3.8% CHD-FA twice daily for 3 days and were monitored for a
week. Because no adverse events occurred, Group B received 40 mL of 3.8% CHD-FA twice
daily for a period of 3 days. In part 3, both groups received either 40 mL of 3.8% CHD-FA or
placebo twice daily for a period of one week, followed by a one-week washout period before
crossover to the alternative treatment schedule. Parameters used to establish safety were electrocardiography,
a physical examination, a health questionnaire, and hematology and biochemistry,
determined at baseline, during regular calculated intervals, and at the end of each part of the
study. A skin prick test was done as part of the screening process and, from the result, the allergen
the participant was most allergic to was then selected, along with the positive histamine and
negative control to be repeated at the start and end of each respective stage.
RESULTS: Safety parameters remained constant throughout the trial. A significant decrease in
skin prick test results was observed.
CONCLUSION: No severe adverse events occurred, establishing that CHD-FA to be safe at doses
up to 40 mL twice daily for a week and that at this dosage CHD-FA acts as an anti-inflammatory
agent. These findings confirm earlier animal data.
