My father in law have taken 冬蟲夏草 which is 膠囊 for over 8 years. It is very good since he said more 精神. It is pharmanex. My husband also use it. But I don't know if BB can or not. May be I will ask my friend who is a nurse who introduce to 冬蟲夏草 me.
If good, I will consider for my BB too
Pharmanex 冬蟲夏草 is $250 with 120 capulse. This is membership price. I find it is quite reasonable and effective for my father in law who has taken over severall years
