Kino on the surface of the trunk of a stringybark eucalyptus tree. Kino is produced by specialised cells (traumatic parenchyma) that develop following surface wounding, damage from insects or splitting (as here). Initially a viscous red fluid, here it has hardened into a solid amber-like mass (centre, red). Its main chemical component is an astringent tannin, kinotannic acid. Kino has been used in the past in tanning, in traditional medicine and as a dye. Modern research has demonstrated anti-microbial activity in the kino of some Eucalyptus species. The ducts through which the kino is exuded (kino veins) are regarded as a defect in timber. | |
