Tuttha
Tuttha is blue vitriol, copper sulphate — Sasyaka. Rasaka, the zinc ore, carries the same name in some nighantus. In Ushakadi, a group of salts and mineral astringents, it is the copper salt.
1 of these 6 names are not yet written up in Laisha's dravya library. The group is printed whole either way, because a gana with members quietly left out is not the gana.
