Abstract
A method of producing an aerosol-generating element for an aerosol-generating article or system is provided, the method including the steps of: preparing a matrix polymer solution including a matrix-forming polymer in water; adding a plurality of aerosol-generating formulation components to the matrix polymer solution to form an aerosol-generating solution, in which the aerosol-generating formulation components include a polyhydric alcohol and at least one alkaloid or cannabinoid, and in which the aerosol-generating solution includes at least 0.5 percent by weight of the at least one alkaloid or cannabinoid; forming a discrete portion of the aerosol-generating solution; adding the discrete portion of the aerosol-generating solution to a cross-linking solution of multivalent cations to cross-link the matrix-forming polymer; and removing the aerosol-generating element from the cross-linking solution and drying the aerosol-generating element.
