Calabar Coast

The calabar bean (the seed of Physostigma venenosum, Fa-baceae) was formerly used for trial by ordeal in Eastern Nigeria in an area known as the Calabar Coast (Holmstedt, 1972). By this method, the guilt or innocence of the accused is determined by whether that person survives after ingesting extracts or concoctions prepared from the plant. The seeds of the calabar bean contain a number of indole alkaloids derived from tryptamine and 5-adenosyl methionine. A concerted ring closure and nucleophilic attack on 5-adenosyl-methionine appears reasonable, but neither this mechanism nor the origin of the carbamate group have been well studied (Fig. 35.11).
