This is a decoction i made using the following herbs chaga mushroom poria mushroom rehmannia root codonopsis root eleuthero root licorice root rhodiola root chrysanthemum flowers and lo han kuo i purchased and obtained these various herbs from one of the following site, mountainroseherbs.com drkangformulas.com shamanshackherbs.com or hyperionherbs.com but hyperion offers already prepared extract powders, and you also have dragonherbs.com and also ebay.com i think i got some of the herbs too from presentmoment.com but im not positive on that name, you simply bring a pot of water to a boil reduce the heat and let the herbs simmer for a while until the water has reduced by half, after you consume the liquid you can reboil the herbs again several more times, in the very same manner and still get medicine from them, almost all the herbs in this video are adaptogenic and some of the most powerful herbs you can obtain for personal health and boosting your immune system, hope this helps and sorry im new to posting videos on youtube, will get better as time goes :0)
