[Japanese variant]「Night soil」「lie prostrate」「orifice」and「netting in tray」as poultices removed from genitals, but note however that formerly the upper-right elements likely were either「rocks, mineral」or「hand on orifice」(石 or 右 in 醢). SALT and BRINE solutions were known to kill bacteria and useful medical treatments of various genital, vaginal, and anal infections (STINGING AND PAINFUL) as salty enemas, douches, and poultices.「Night soil」itself is often rather salty, the means for an organism to dispose of excess ingested salt.
　Salts are essential for animal life due to their ionization chemical properties, but toxic for nearly all land plants and bacteria. Without some salt animals will die, but ingesting too much will also kill most animals, and both situations may account for「ground, lying prostrate with mouth over dish」as in ingesting an amount within proper limits or you will find yourself laid out on the ground.
　SALTS were used to cleanse, dry, and disinfect the flesh seam created by bending over the sole of each foot into a hairpin shape, and it requires little if any imagination to understand how this condition also applies to all the given meanings. Concubines and service providers used salts in the deep skin slits of their bound feet (鹵), a likely source of the English expression meaning to accept the bad along with the good but have some skepticism and reservations,「take it with a grain of salt.」Only a single grain of salt remaining in the flesh seam of a no-longer-integrated foot would cause discomfort to a client. Salts in the deep skin slits of bound feet accomplish two things at once: dry the skin, and disinfect any wounds or straggling bacteria deposited there by dignitaries.
　Cattle given unlimited access to large salt licks have been known to ingest quantities sufficient to kill the animals, likely by causing a heart attack due to sodium, potassium or other ion imbalances. Another original glyph was「warning to maintain distance from the saline brain fluids on dinner plate」(鹽). Preserving food with salt is effective because salt kills the bacteria that normally would digest the food:「While people have used canning and artificial refrigeration to preserve food for the last hundred years or so, salt has been the best-known food preservative, especially for meat, for many thousands of years. A very ancient saltworks operation has been discovered at the Poiana Slatinei archaeological site next to a salt spring in Lunca, Neamţ County, Romania. Evidence indicates that Neolithic people of the Precucuteni Culture were boiling the salt-laden spring water through the process of briquetage to extract the salt as far back as 6050 BC. The salt extracted from this operation may have had a direct correlation to the rapid growth of this society's population soon after its initial production began. The harvest of salt from the surface of Xiechi Lake near Yuncheng in Shanxi, China dates back to at least 6000 BC, making it one of the oldest verifiable saltworks」
