Minerals and Metals in Ancient India v2.c45.s7.3

v2.c45.s7.3

Yaśodhara had quoted Nāgārjuna in his *Rasaprakāśasudhākara*: *pārado rasakaścaiva dehalohakarāvubhau* that both *rasa* or *pārada* (mercury) and *rasaka* (zinc ore/metal) when administered, make the body strong. Both the metals are distillation products, and hence the similarity in the names: *rasa* and *rasaka*.
