may contain a variety of different fluids collected from different sources within the animal in their raw forms the fluid mixtures may include crude contributions from the blood lymphatic system nervous system cells interstices and various body cavities the particular mixture obtained depends on how the animal being processed is cut dismembered ground pressed or otherwise handled or a general water soluble fraction can be had by first pulverizing or grinding the animal tissue or subjecting it to partial or full hydrolysis or enzymatic digestion and then extracting the product with water the fluid types for the stimulant composition may be used in their raw form but are preferably further fractionated and filtered to remove unwanted oils fats and particulates that detract from their aesthetic appearance moreover it is equally acceptable to use the aqueous fractions in their original hydrated state or to use their dehydrated liquid concentrates that are later re constituted with added water likewise dry powders produced by spray drying or freeze drying the original liquid or water soluble fractions of the animal that again are later re constituted in water function are satisfactory assorted commercially prepared dehydrated animal extracts are also available from various suppliers alternatively instead of using fluids taken from once live animals it is possible in those cases where the chemical recipes are known to fashion a synthetic mixture that simulates the active components within a water soluble fraction taken from a particular animal species several of these recipes for different animal species are shown in table.
