The common names of physostigma are Ordeal Bean,
Chopnut, Calabar Bean. Physostigma is found in West Africa and was
later introduced into Asia and Brazil. It was proved by Christison. The
mother tincture is prepared from the seeds in which the active principal
Physostigmene is present, and dilution from it.
It is claimed that Physostigma relieves Myopia, night
blindness and some other diseases of the eyes. It has also been
employed in general paralysis of the insane and in progressive
muscular atrophy and also in tetanus of the traumatic origin.
