This is woven from the yellow silk spun by silkworms, not dyed silk.
Decocting it in water for washing treats ulcerated and rotting smallpox sores; burning it to ash stops bloody dysentery and metrorrhagia (uterine bleeding). It resolves patient's polydipsia (excessive thirst), and treats bladder damage in postpartum women.
For postpartum bladder damage, characterized by inability to urinate with continuous dribbling and astringency, take one chi of yellow silk, along with Cortex Moutan (Mudanpi) and Rhizoma Bletillae (Baiji) ground into powder, one qian each. Decoct until the silk disintegrates, then administer the liquid. The patient should avoid making noise during treatment. (Verified Formula 1.)
For metrorrhagia (heavy uterine bleeding), mix ash of yellow silk, ash of palm fruit, ash of Beijing ink, and ash of lotus leaf. Administer mixed with water and wine to stop bleeding immediately. (Formula 2.)

Cotton cloth, which is dyed using indigo.
When heated and applied as a compress, it treats eye pain accompanied by inability to close the eyes, and also treats redness of the eyes. Burning it to ash and applying it topically treats chronic malignant ulcers and moxibustion wounds. Soaking it in water and drinking the liquid resolves toxicity from various substances, irritant toxins, and erysipelas (Dan Du). It treats cracked lips, oral malodor caused by erysipelas. Soaking in water and applying as a patch treats chest burns caused by heat pathogens; boiling in vinegar and applying externally treats muscle spasms extending into the abdomen. Burning it together with beeswax and fumigating malignant ulcers prevents them from rotting when exposed to water. Rolling mugwort male plants into moxa cones, treating sores: if pus flows, healing occurs. For sores injured by wind-water pathogens, fumigation extracts foul fluids; for coughs due to wind-heat, fumigation causes turbid phlegm to descend.
