Until the Middle Ages used to a paste stirred mixture of auric pigment (arsenic aperture, toxic), slaked lime and starch.
Pure auric pigment is a mineral that is mined in various places in the world, including Europe. It contains 60.9% arsenic and 39.1% sulphur, but can also contain admixtures of selenium (Se), antimony (Sb), vanadium (V) and germanium (Ge). In addition, the mineral is often also contaminated with clay minerals, silicon dioxide (SiO2) and/or stibnite (antimonite, Sb2S3).
For Rhusma Turcorum the following prescription can be found in the Lexikon der Kosmetischen Praxis by R.Volk:
- Auripigmenti 2,0
- Calcar.hydric. 10,0
- Amylum 5,0
This powder was mixed with some water to a paste and applied for 2-3 minutes on the area to be depilated.
