"Those born from feces have an origin similar to those born from phlegm. Their location is the large intestine; as they grow, they crawl downward, but if they should turn toward the stomach, from time to time the patient's belching and respiration will smell of feces. Their distinctions of form and color are: some are minute and round in girth, white, long, and resembling wool fibers; some, however, are thick and round in girth, dusky, blue, green, and yellow. Their names are kakeruka, makeruka, leliha, saśūlaka, and sausurāda. Their effects are diarrhea, emaciation, roughness, and the production of goose bumps; and these very worms, pricking and causing itching at the anal orifice, dwell around the anal orifice, and having become stimulated, they emerge through the anus excessively. Such is the specific origin and so forth of worms born of phlegm and feces."
