You can take either 2 doses 12 hours apart or 1 double dose a day, every day for a month. You are then set for 3 months then you repeat the monthly dose, then 90 off, blah, blah you get it.
Birm is designed to strengthen your immune system and comes from the Orient region of Ecuador. $20 bucks for this bottle.It can be had at most pharmacies or boticas without a script.
I have to say this stuff makes you feel better, or it did for us.
