Ginger For Your Hair
The sticky viscuous liquid within the bracts of this shampoo ginger, Zingiber zerumbet has been used traditionally by Polynesians as hair shampoo. The whole "cone" would be taken to a river, and upon a light squeeze, the liquid would ooze out and ready to be applied. The chemical is said to impart a lasting shine to the hair. It is apparently effective, some famous (I think) shampoos - like Paul Mitchell and Freeman put it in their products.
More recently, an oil known as Zerumbone extracted from its rhizome is found to have anti-tumour properties as well.
