Abstract: Hydrastis canadensis is used for treating feline-specific disorders, such as, feline-specific fungi, feline specific-coat degradations, and feline-specific strong feces odors. At least one vitamin can also be added to the hydrastis canadensis. The hydrastis canadensis is taken orally by the feline either in tablet, powder, or liquid form.

Abstract: A method is provided for preconditioning and cryopreservation of cells harvested from a donor. Cells are suspended in a cell conditioning and cryopreservation medium containing a cryopreservative such as Dimethyl Sulfoxide (DMSO) and the suspension is incubated for a period of at least ten minutes and the cells are frozen. The medium includes adenosine, a calcium channel blocker, and a cell nutrient matrix comprising a sufficient amount of cell nutrients to sustain the metabolic needs of the cells during incubation without producing detectable levels of lactate or substantially depleting the nutrient substrates to maintain viability of the harvested cells. In some embodiments, a cryopreservative is added step-wise before the cell suspension is frozen and removed step-wise after the cell suspension is thawed.
