Title: Solidified fulvic acid powder
Inventor: MATSUBARA YOSHIMASA
IPC: A61P3/02
Filed: 2011-08-30
Abstract: PROBLEM TO BE SOLVED: To solve a problem of most of conventional fulvic acid applications wherein effects are verified basically in aqueous extracts while numeric values of the fundamental fulvic acid content are obscure.SOLUTION: When a fulvic acid liquid is solidified and pulverized into powder, and then diluted with water or alcohol, a compounding ratio of the fulvic acid can be digitized in terms of 100-0.00% and indicated precisely. Since controlled display of an addition quantity is available, a consumer can use a reliable safe product. In a human, a content of the fulvic acid, which is a basic substance essential for organisms such as animals and plants on the earth to thrive, is decreased along with the age and its absorption from foods becomes difficult. In consideration of radioactive pollution problems particularly in Japan and worldwide problems about nuclear power generation, the fulvic acid is a substance which may serve as a second vitamin or penicillin. It is 50-60 years from presentation of the fulvic acid, however, it must be a substance just needed nowadays.
