Which plant species is used in 30000 B.C., Phormium or Bolbitis?
Phormium Phormium is a genus of two plant species in the Asphodelaceae family. One species is endemic to New Zealand and the other is native to New Zealand and Norfolk Island. The two species are widely known in New Zealand as 'flax' and elsewhere as New Zealand flax or flax lily but are not related to flax, which is native to the region extending from the eastern Mediterranean to India and which was used by humans in 30,000 B.C.
Mezerein Mezerein is a toxic diterpene ester found in the sap of "Daphne mezereum" and related plants. Plants of the genus "Euphorbiaceae" and "Thymelaeaceae" possess a wide variety of different phorbol esters, which share the capacity of mimicking diacylglycerol (DAG) and thus activating different isoforms of protein kinase C. Mezerein was first isolated in 1975. It has antileukemic properties in mice, but it is also defined as a weak promoter of skin cancers in the same species. All parts of the plants contain an acrid and irritant sap that contains mezerein, thought to be the principal poison. The sap is especially prevalent in the bark and berries.
