Thank you.

Would you like to see my collection of paper as well? I have a small piece from Dunhuang and several pieces from the Nara Period which are over a thousand years old. The paper still rattles when you shake it (as it did when it was first made). They’re brown now but were originally bright yellow from being dyed with extract from the Amur cork tree (Phellodendron japonicum). The dye contains a natural insecticide which helped preserve the paper and the religious texts written on it.

There's a touch of Chuck Berry about "rattles when you shake it " .
And not a million millions from berries , does the insecticide come the drupe of the tree ?
Pity it isn't native here we could do with some on another thread .

No, it comes from the wood (and can also be used medicinally). Turmeric also has insecticidal properties and is similar in colour (though brighter than Amur cork tree). Large cotton bags for storing folding screens are often dyed with turmeric.
