Shoyu: Japanese soy sauce is a popular ramen seasoning in the Kanto region of central Japan, originally emanating from Yokohama. Traditionally it's paired with clear to brown chicken, seafood, and occasionally pork or beef-based broths, though these days shoyu is used willy-nilly by ramen chefs throughout Japan.
IM injections can be given in a large muscle in the buttock, upper arm, or thigh. It is best to use the buttock or thigh instead of the arm if: the amount to inject is more than 2 ml (2 cc). (But you should never inject more than 3 ml (3 cc) in a single dose. Use 2 injections instead.)
Preparation: Use solution as provided (150 unit/1 mL vial); do not dilute further. Inject subcutaneously or intradermally into the extravasation site using a 25-gauge needle or smaller. Dosage: The dose is 150 units (1 mL) given as five 0.2 mL injections into the extravasation site at the leading edge; change the needle after each injection.
