正中平 this TCM shop sells concentrated birds nest. Everyday or every other day eat a tablespoon is enough. But it's also costly, I think $70 per bottle though they have buy 2get 1 or 25% off offer frequently.
I think all birds nest quite expensive.. The more affordable ones also not sure if quality is gd.. Maybe can consider alternatives like white fungus like what GBOB cooked.l. Apparently nutritional value similar?
wah not cheap also hor! yalor. i think i better guai guai stick to white fungus lar... btw is there a limit in taking the white fungus soup that GBOB recommended? weekly?
