Peter,
This may be best answered by Doug, Malcolm or Renee who have more tincture 
experience than I. The Chaga mushroom looks very interesting.  Tincturing of 
muchrooms is common and in fact my first tincture was of a fungus because of 
the high cost of the commercial tincture. 
One problem of tincturing is determining the type of solvent the targeted 
substances are soluble in. Generally I prefer to extract all the components 
within an herb so I use an alcohol tincture that should extract both water and 
oil soluble components. More recently I have also used DMSO to help increase 
the boiavailibility of some substances that have a low bioavailibility. Also 
some substances are more soluble in DMSO although some are not. 
Finding the solubility of all the individual components within a plant is 
difficult if not sometimes impossible. Up till recently I used a water 
extraction, decoction, or alcohol or DMSO tincture. Lately I have been 
considering alcohol with DMSO in a single tincture but I don't for sure that 
that it is better. 
In answer to your question, DMSO can improve bioavailability esp with 
substances that have a lower biiavailability normally. It may not always be 
necessary but it won't hurt that I know of. I think that it might be good to 
use with Chaga given the large number of substances contained in it.

Hi Steve, Malcolm, Doug and all,

I have been looking into a mushroom called Chaga lately which grows on birch 
trees primarily and in colder climates. It has a history of immune 
enhancement in Russia and has been used there to help in the recovery of 
cancer patients as well as as a preventative. Its properties can be better 
explained in the links below. I have read of several different ways to 
prepare it.

I am wondering if Chaga tincture could be made with DMSO to help achieve 
good penetration as one might do with herbs. Any thoughts anyone?
