To make the Chaga tinctures, I mix Chaga mushrooms with 100 proof vodka and then let it rest for a month.
Next, I will put the Chaga mushrooms into a gallon of water and boil it for two hours. After two hours, I separate the liquid from the chunks, then mix the Chaga tea liquid with tincture liquid, which is a 50/50 mix of water and 100 proof vodka.
The reason why this is the best way to make and take Chaga is that half the medicinal qualities are alcohol soluble and the other half are water soluble. I have been making Chaga tinctures for 3 years.
