Red Lead

Traditional Use

Primary Actions

• Draws out toxin and dries damp lesions ... historical Qian Dan use centered on external sores, eczema, scabies, and chronic wet lesions that needed a harsh drying mineral.
• Promotes tissue closure in ulcerated or slow-healing skin conditions ... older topical practice used the powder in plasters and ointments for abscesses, burns, and damaged tissue.
• Historically reduced phlegm and settled fright in minute internal use ... this indication is preserved as a historical note only, not as a modern therapeutic endorsement.

Secondary Actions

• Qian Dan belongs to the same toxic lead-mineral cluster as Qian Fen, but it is the oxidized red form and is framed primarily as an external historical medicament.
• This page should stay distinct from `lead-powder` and `red-mercuric-oxide` ... similar color and old surgical use do not make them interchangeable or equally toxic.

Classic Formulas

• External ulcer and parasite powders ... classical use paired Qian Dan with borneol, alum, or other drying minerals for sores, scabies, and damp-toxic lesions.
• Historical plasters for burns or non-healing wounds ... Qian Dan appears in older tissue-closing preparations now viewed through a strict toxicology lens.
• Rare internal pill traditions for phlegm or fright are recorded in older literature but are not carried forward here as practical modern recommendations.

Classical References

• Traditional materia medica describe Qian Dan as an acrid toxic mineral that removes toxin, dries dampness, kills parasites, and promotes flesh growth.
• The same historical sources that preserve these actions also make modern reinterpretation necessary, because lead toxicology now outweighs any casual expansion of use.
