Hi, Does anyone have seen the first hand bird's nest which means it is directly from the cave and has not been treated? As you know, all the bird's nest selling in the market now are treated which means they have been boiled and consolidated again which the seller has added something to it (because the boiled bird's nest cannot been join again) and caused not 100% bird's nest and the profit is how many % of substance that they have put to the bird's nest. I want to make sure the first hand bird's nest is true. Many thanks
