Critical evaluations of different aspects involved in preparation of Hartala bhasma
International Journal of Ayurveda Research, 2023 Arsenic trisulfide, known as Hartala (~Orpiment), is being used as medicine since the time of Hippocrates. However, the use of arsenicals in modern medicine is constrained due to toxicology concerns. Ayurveda has used orpiment as medicine since 2000 B.C.

Elastic, Mechanical, and Phonon Behavior of Orpiment Arsenic Trisulfide under Pressure
International Journal of Photoenergy, 2020 Arsenic trisulfide (As2S3) has been found to be an excellent glass former at high temperature and pressure. However, there is still some scarcity for the elastic and phonon behavior of the orpiment phase. By using the Dreiding force field of the geometry
