Medicine
III Ink Uses and Users
The Greek physician and pharmacologist Dioscorides of Anazarbus (1st century) states the following on the medical properties of ink:
«It is good for putrefactive wounds and for burns, being smeared on thick with water and left alone until cicatrisation; for it automatically falls off once the sores have healed.» (De materia medica 5.162.2)
The ink used in antiquity was composed of natural substances that were recognised in the medical and pharmacological traditions of the time as having a range of therapeutic properties. For example, gum Arabic was attributed astringent properties, suitable for treating open wounds (De materia medica 1.101); soot from pine wood was good for eye complaints (ibid. 1.69), and so on. It is therefore not surprising that ink was also considered a pharmakon, a substance with special properties, in this case medicinal.
