Ficin
Ficain also known as ficin, debricin, or higueroxyl delabarre () is a proteolytic enzyme extracted from the latex sap from the stems, leaves, and unripe fruit of the American wild fig tree ''Ficus insipida''. Ficain was originally called ficin, and ficin was originally a mixture of closely related cysteine endopeptidases produced from any species of the genus ''Ficus'', before the terminology was restricted to a specific cysteine endopeptidase enzyme from a specific species. Cysteine endopeptidases are a group of enzymes that also include the more distantly related papain derived from papaya latex, bromelase (bromelain) extracted from pineapple stem, calpain, caspases, cathepsin B, and chymopapain. Cysteine endopeptidases with similar properties known generically as ficins are present in other members of the genus ''Ficus'', and many species appear to contain multiple types of these enzymes. Somewhat confusingly, the terms ficain and ficin are often treated as synonyms. Ficain is ...

Ficus Insipida
''Ficus insipida'' is a common tropical tree in the fig genus of the family Moraceae growing in forest habitats along rivers. It ranges from Mexico to northern South America. Taxonomy The tree was described in 1806 under the scientific name ''Ficus insipida'' (literally "insipid fig") by Carl Ludwig Willdenow, having studied the herbarium specimens collected in Caracas by the gardener Franz Bredemeyer in the 1780s during the . Willdenow reports its fruit are tasteless. Incongruously, among the many species of figs to grow in the region, this species is in fact recognisable by its large and sweet figs (when ripe). In the 1960 ''Flora of Panama'', Gordon P. DeWolf Jr. lumped the species ''F. adhatodifolia'' and ''F. crassiuscula'' as synonyms of ''F. insipida'', but his taxonomic interpretation was not followed by subsequent authorities. ''Ficus'' expert Cees Berg distinguished two allopatric or almost allopatric subspecies in 1984: * ''Ficus insipida'' subsp. ''insip ...
