We can eat the nuts of the Maracta nut tree (bertholettia excelsa) along with the resin to treat
scars and wrinkles. It’s also a strong adhesive resin for certain materials:
Note that this isn’t the the respective amber.
We could use the resin from the Maracta nut tree (Brazilian nut tree) to amberize things, because it has a high adhesion and turns into a dense amber like substance when being dried, so we dry it while it’s inside the resin.
The resin could either be natural or synthetic.
Note: These are the Maracta nuts for wrinkles and scars as example, although I think that it must be combined with the resin as my feelings tell me.
