Listen now to the detailed account of prameha and related ailments, as described in the ancient teachings. The sages observed that prameha, a disorder marked by abnormal urination, is distinguished by the qualities and colors of the urine itself. In some, the urine appears clear, very white, cold to the touch, odorless, and closely resembling pure water. In the condition known as udakameha, the urine is watery yet slightly turbid and carries a slimy texture. When the disorder is ikṣumeha, the urine becomes exceedingly sweet, akin to the juice pressed from sugarcane. There are further variations: in sāndrameha, the urine is thick and stale, while in surāmeha, it separates like wine—clear on the surface but dense below. Śukrameha is marked by a striking sign: the patient’s hair stands on end, and the urine is thick, white like flour, resembling or mingled with semen. If one suffers from sikatāmeha, the urine contains sandy particles; in śītameha, the flow is copious, sweet, and very cold. In śanairmeha, urination becomes slow and gradual, while lālāmeha is characterized by slimy urine streaked with threads of saliva. Kṣārameha causes the urine to resemble alkaline water in its smell, color, taste, and touch. Nīlameha turns the urine blue, and kālameha turns it black, like ink. Beyond these, eruptions may appear on the body—at the joints, vital spots, and along the muscular channels. These eruptions are raised at the edges, sunken in the center, dry, and painless. The śarāvikā eruption is shaped like a shallow dish, while kacchapikā burns persistently and is likened by the wise to the shape of a tortoise. Vinatā is a large, blue eruption, and jvālinī arises on the skin with intense burning and severe pain. Masūrikā is an eruption that is red and white, with bursting blisters, severe in nature, and shaped like a lentil. Putriṇī looks like mustard seeds, brings great pain, and causes ulceration of the tongue; it may be large, small, or minute. Vidradhikā is round like the root of the vidārī plant, hard, and has features of an abscess. Putriṇī and vidārī are particularly difficult to endure and tend to arise in those with abundant fat, while the other eruptions, dominated by pitta, appear in those with little fat. All these pustules manifest according to the aggravation of the doṣas; yet, even in the absence of diabetes, they may arise from corrupted fat. They often go unnoticed until a change of color occurs—yellow or red hues, or the lack of early signs of diabetes, should be watched for carefully. When a person passes such urine, it is said to be raktapitta. Symptoms include sweating, body odor, looseness of the limbs, drowsiness, cravings for food and sleep, burning sensations in the heart, eyes, tongue, and ears, heaviness, and excessive growth of hair and nails. There is a fondness for cold, dryness of the throat and palate, sweetness in the mouth, burning in the hands and feet, and, as a forewarning of diabetes, ants are seen gathering around the urine. Diabetes itself brings thirst, sweetness and stickiness in the mouth, and a variety of disorders. When the condition arises from fullness, it is due to kapha; when the doṣas are depleted, it is of vāta nature. Diabetes caused by kapha and pitta manifests fully and gradually, and if it arises from sexual activity, it is chronic when pitta predominates. Only those cases not ordained by fate are deemed curable. Turning now to the cause of abscess, Dhanvantari spoke to Suśruta: “Hear, O Suśruta, the origin of abscess and the condition known as gulma. These arise from the consumption of food that is stale, excessively hot, dry, rough, or burning. Lying on uneven beds, improper movements, and disturbances of the blood further corrupt the flesh, fat, marrow, and bone, making the abdomen the seat of disease. This swelling, whether external or internal, brings severe pain and suffering. It may be round or elongated, and is known as abscess. Formed by the separate or combined action of the doṣas and blood, the abscess moves through various parts of the body, is hard, knotted, and does not discharge easily. Internally, it is deep and severe, increasing like a tumor, and may discharge like an anthill, weakening digestion. Abscesses can arise in the navel, bladder, liver, spleen, heart, abdomen, and groin. When present in the heart, they cause trembling and intense pain in those regions. The head of the swelling is dark-red, its maturation is irregular, and its shape uneven. It is accompanied by loss of consciousness, confusion, distension, oozing, creeping sensations, and even noise. When pitta is involved, the abscess appears red, coppery, or blackish, and brings delirium, fever, and burning. If it arises suddenly and matures quickly, it may be pale and itchy due to kapha. When all three doṣas are disturbed, there is distress, chills, stiffness, yawning, loss of appetite, heaviness, delayed onset, and poor digestion. The strength of the disorder may bring abnormal stools and both external and internal signs: black eruptions, dark discoloration, intense burning, pain, and fever. In women, signs of pitta are also found in external bleeding. Disease can also be caused by blood from injuries, such as those inflicted by weapons. When a wound is agitated by wind, the blood provokes pitta, producing the symptoms of both pitta and blood, and abscesses with many complications. The variations in these complications are recognized according to the afflicted site. For example, if swelling occurs at the navel or bladder, there is difficulty in urination. Obstruction of breathing and exhalation, spleen disorder, excessive thirst, and throat obstruction occur when the kloma is affected, along with pain throughout the body and heart. Further symptoms include fainting, darkness before the eyes, cough, palpitations in the heart and sides of the abdomen, and the generation of doṣas within. Pain may also arise in the thigh-joints, groin, hips, back, and sides, as well as in the anus, with obstruction of wind. In these cases, one should recognize whether the swelling is raw, ripe, or suppurated. Some abscesses, when ripe, discharge upward from the navel, while others discharge downward from the anus. Abscesses arising from the anus, breast, or navel are due to the moistening of the doṣas, and the combined disturbance of the doṣas causes changes at their respective sites. When mature, if the abscess is located at the navel or bladder, it may rupture either internally or externally. If the abscess is depleted and complications arise, suppuration occurs within. Such abscesses may develop in wicked women and sinners; and if the fetus dies in the womb, a hard swelling may also arise. Thus, the sages described the many forms and signs of these disorders, so that one may recognize and respond to them with wisdom and care.
