The ginseng I tried are in pill format.
For some reason, my testosterone levels went higher than normal, leaving me MORE prone to anger and bad temper.
I stopped eating it, and went back to normal.
I think (I read it somewhere as well) that ginseng is supposed to do that.
For swallow's nest, I have a whole bunch of glass canned ones which I did not eat/drink any way.
Then, I found that the preservatives used to preserve them are very bad for you.
But, this is only for the canned versions.
The fresh or semi fresh ones, or "un" canned ones are much better, where you have to cook it yourself.
Most swallow's nest (the good ones) come from Malaysia.
More and more are coming from Thailand, but the best ones come from Malaysia.
