Garudapurana 1.165

Glorious Garuḍa Purāṇa — 165 / Dhanvantari said: / Worms are declared to be of two kinds according to the division between external and internal; / and fourfold according to origin from external dirt, kapha, blood, and faeces.

By name they are of twenty kinds. Among them, the external ones arise from dirt, / having the size, shape, and colour of sesame seeds, residing in the hair and clothing.

Having many feet and minute, they are named yūkās and likṣās; / of two kinds, they produce eruptions on the trunk, itching, and swellings.

The internal ones are sole causes of kuṣṭha; those born of kapha have external manifestations; / by means of sweet food, jaggery, milk, curds, fish, and freshly cooked rice,

they are born of kapha in the stomach, grow, and crawl everywhere. / Some resemble broad roots, some are like earthworms,

having the shape of sprouted grain shoots, thin, long, and tiny, / white and copper-coloured; by name they are sevenfold:

antrādās, udarāveṣṭas, hṛdayādās, mahāgudās, / cyurus, darbhakusumas, and sugandhas; and they cause

nausea, salivation from the mouth, indigestion, loss of appetite, / fainting, vomiting, fever, abdominal distension, emaciation, sneezing, and chronic rhinitis.

The organisms born from blood, located in the blood-carrying vessels, are minute, / footless, round, copper-colored, and some are invisible due to their subtleness.

The keśādas, romavidhvaṃsas, romadvīpas, and udumbaras— / these six perform the singular work of producing leprosy, along with the saurasas and mātaras.

Those arising from feces are born in the large intestine and move downwards; / when they grow large, they may also move upward toward the stomach.

Then they make the breath of his belches smell of undigested feces; / broad, round, slender, and thick, they are brownish, yellow, white, and black.

Those worms are known by five names: kakerukas, makerukas, / sausurādas, those called saśūlas, and lelihas; they indeed produce

diarrhea, colic, constipation, emaciation, roughness, pallor, / horripilation, loss of digestive fire, and itching in the rectum when going astray.

Thus ends the one hundred and sixty-fifth chapter, named 'Diagnosis of Worms,' in the Code of Conduct, the first part of the first section in the glorious Garuḍa Mahāpurāṇa.
