Abstract
A method for preserving cut plant material comprising immersing, within a pressure vessel, the particular material in a treatment agent constituted of glycerin, ethylene glycol, diethylene glycol, triethylene glycol or mixtures thereof; said treatment agent having a specific gravity within the range of 1.10 and 1.16; there being a suitable dye provided with said agent. The immersed material is subjected to an applied pressure greater than atmospheric, as within the range of 5 to 40 psi; but under ambient temperature and humidity, the material being maintained under such pressure for a predetermined period dependent upon the applied pressure for absorption of the agent and dye. The material is then washed and thereafter permitted to be dry under room conditions.

A method of processing cut plant material comprising immersing the plant material to be processed in a liquid treatment agent comprising a polyol or mixtures thereof and having a specific gravity within the range of 1.10 to 1.16, subjecting the immersed plant material to a pressure within the range of 5 psi. to 40 psi. under ambient temperature for a time interval of between 2 to 7 days for absorption of the agent in the material, then withdrawing the plant material from the pressurized immersed state, and then permitting the withdrawn plant material to dry under ambient pressure and temperature.
