I do hear from colleagues that birdnest will trigger asthma, but personally i dont recall myself got asthma attack after taking birdnest (i do have asthma since young). Guess it's depends on individual.
I went to see a chinese doctor at Yu Ren Sheng. She told me that birdnest may cause phlegm to some pple. She did say i can take birdnest, but moderately. And if it does cause phlegm for me, then i should stop taking it.
But with so many range of birdnest out in the market, are their nutrients all the same as there's a wide range of cost difference in them?
Anyone can advise on the different type of birdnest??
