Description
Jinshaku – 腎積, じんしゃく – “Kidney infection”

• About this mushi: an infectious germ which resembles & behaves like a wild boar, it has a very long tongue and fine red tendril-moustache. its back is furry and white and Its underbelly and tail are smooth and red, its thin legs look like sticks! It makes its home in the kidneys and naval; underneath the hosts belly button. Teams of small white worms follow it around as it rampages through the hosts kidneys, soon it leaves and rampages up and down; throughout the hosts entire body… Symptoms include a weak pulse, dark complexion and severely stinky, putrid smelling breath. The host will also begin to crave only the most salty of foods.
• Cures: as with many of the other mushi, it can be treated with various acupuncture techniques. (unfortunately, these treatments where only written about vaguely and only passed along orally from teachers to students, given the age of the text; they are quite likely lost to time! (Humorously, the Kyushu national museum’s guide book notes, that this one says that “its impossible to explain it all in one sentence!”) – The entry also goes onto mention that the area where this one lives (“below the belly button”) is of the “water element” in “Wu-xing” (Chinese Elemental Theory) (which probably explains why it can move wherever it likes throughout the hosts entire body, unlike most of the others that are confined to one organ/general location)

• History: Yet Another One out of 63 ‘KanNoMushi’ ‘疳の虫’ (germ/parasitic Yokai) from the “Harikikigaki” 針聞書 (“The book of needles.”) – A mysterious book about acupuncture & medical knowledge written in 1568 by a resident of Ibaraki City, Osaka Prefecture, Japan.
