Abstract: Disclosed are devices and methods for rehydrating plant matter or plant-derived matter and infusing such matter with terpenes and other volatile compounds. In one embodiment, a device to rehydrate and infuse plant or plant-derived matter comprises a first housing portion comprising a central column and a second housing portion configured to be coupled or locked to the first housing portion. The central column of the first housing portion can compromise a rehydrating agent, an infusing agent, and a hydrosol infuser. A method of using the device is also disclosed. The method can comprise rotating the first housing portion with respect to the second housing portion to open the device, placing the device within a bag or container containing the plant or plant-derived matter, and sealing the bag or container containing the plant or plant-derived matter and the device.
