「Suppress, conquer, subdue, uncouth barbarian savagery of body meat」: at the outset SOAP was manufactured from fat (mixed with ash), and elements as「body meat of the uncouth」may be referring to that sort of tissue…「body meat」of a service provider with no-longer-integrated feet who sat most of the time, only exercising the tongue and lips, vaginal, and anal sphincter muscles on a regular basis due to being unable to stand upright might tend to become a bit flabby, and in fact a would have serious need for SOAP after providing services to each client's「meat with rod taut and erect inside arch of no-longer-integrated foot」: men in dynastic China masturbated by wrapping the erect penis with no-longer-integrated feet: see Chinese erotic art for details.「…Bound feet were once considered intensely erotic in Chinese culture….

　Early humans were all cannibals, and would have had no compunctions against utilizing human lipids to manufacture SOAP. The human PANCREAS performs many vital functions, but one major purpose is to produce enzymes essential for metabolizing lipids, in other words, changing animal fat into other more useful items, the same as humans do during soap production. The English term PANCREAS derives from the Greek「all body meat」「whole flesh.」Elements「body meat or flesh with eat all, devour, exterminate, kill all, raze, to flatten, break down」describes one of the major functions. The PANCREAS secretes a range of various digestive enzymes into the stomach essential for「breaking down meat, fats, and all other foods」into component parts that can be utilized as nutrition, just as the elements depict.
　Moreover, the PANCREAS produces the hormones glucagon and insulin that regulate blood sugar and body fat. Out-of-balance insulin causes diabetes. The PANCREAS produces a series of neurotransmitter hormones, most notably serotonin, that greatly affects「all body meat, the whole flesh」of an individual. The PANCREAS refers to what in the culinary world are SWEETBREADS, perhaps as it relates to blood sugar levels? note that modern Japanese uses 膵臓 suizō for pancreas, the「meat clustering with internal organs」and that maybe the sweetness?
