Zusammenfassung:PROBLEM TO BE SOLVED: To micropulverize a natural product having a maximum particle diameter of 5,000 μm or less by single stage crushing at ordinary temperature so as to reduce the maximum particle diameter to 30 μm or less. SOLUTION: In a method for preparing the micropulverized natural product, the natural product having a moisture percentage of 5 wt.% or less and a maximum particle diameter of 5,000 μm or less is micropulverized in an organic medium by the single stage crushing using a micropulverizer having a milling function so as to reduce the maximum diameter to 30 μm or less. A micropulverized natural product-containing composition contains the micropulverized natural products having a moisture percentage of 5 wt.% or less and a maximum particle diameter of 30 μm or less, and the organic medium. The amount of the organic medium to 100 pts.wt. of the natural product is 1-15 pts.wt.
