A method of creating an extract of myceliated agricultural product for human consumption includes providing an agricultural substrate such as rice, where the agricultural substrate has been inoculated by liquid media comprising an aliquot of culture derived from liquid-state fermentation. The culture being selected from the group consisting of Basidiomycota and Ascomycota fungi. Next, the step of enabling mycelium growth on the substrate by controlling temperature, humidity and sterility of the environment. After mycelium growth on the substrate reaches a desired stage, then the step of boiling the substrate in water and separating the water-substrate mixture into aqueous component and non-aqueous components creates an extraction.
