Yucca was used by the southwest native americans for washing their hair .
西南部的印第安人曾用丝兰来洗头发。
Even after modern soaps became available , many tribal groups still preferred yucca because of its gentle way of cleansing one 's hair , without stripping or drying its structure .
即使后来有了肥皂，许多部落仍然喜欢用丝兰，因为在用它洗头时，头发本身结构不会被破坏或干枯分叉。
As well as offering packaged goods aimed at hispanic customers , as wal-mart does in some stores , these shops sell prepared dishes , including red beans with pig 's feet and stewed chicken , and perishables such as yucca root .
One thing obama did not spell out is how the us will deal with a new generation of waste now that it has abandoned plans for a storage facility at yucca mountain .
In the us , a site was earmarked decades ago at nevada 's yucca mountain , 100 miles from las vegas , but the obama administration finally abandoned the scheme last year .
