Guest guest Posted October 29, 2003 Report Share Posted October 29, 2003 Jim, Phil, and Karen /Hi Karen :-}, Jim's question was answered adequately by Karen, although it should be mentioned that a double extraction of ling zhi would be best, first in alcohol then in water and finally combined. There are other compounds besides polysaccharides in this medicinal and a combination extract is better than a simple preparation. These are some of the details that set home preparations away from one's made by plant pharmacists. Bob asked about spigeric extracts. This is when a portion of the marc (the spent medicinal after extraction by a hydro/alcoholic solution) is burned completely and then added back into the preparation. This method is not done much these days (I only know of one company that treats all their extracts this way) but is a very interesting and valid method. I have not much of this type of preparation due to the burning part. It is difficult in a simple lab situation and can be quite messy. thomas > Phil: > > What's the rationale for the different percent of ethanol for > extraction? > > > Jim Ramholz > > " Karen Vaughan " <creationsgarden1 > Diluting Everclear > > Jim- > > Resins usually need quite high alcohol percentages to extract whereas polysaccharides need around > 25% or they will clump, and other compounds each have their preferred extraction range.

It is suggested by Simon mills in principles of phytotherapy that polysaccharides are probably not the active constituent of many of the herbs that contain them as the typical dosages of these herbs are far too low to deliver the amount of polysaccs that research shows is necessary to elicit an immune response. perhaps smaller amounts of polysaccs work with other compounds in the whole plant. Mills also has some interesting stuff to say about flavonoids as well. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted October 29, 2003 Report Share Posted October 29, 2003 Thomas, spigeric extracts.... a very interesting and valid method. Can you tell me the intent of or the expected benefit in using this method? What do you mean by " valid " ? And, the work spigeric is not in any of my dictionaries. Do you know the actual meaning?

Guest guest Posted October 29, 2003 Report Share Posted October 29, 2003 I have a question. When I make an extraction of a formula, I usually soak and steam the formula in a litre or two of the alcohol for a period of 30 - 45 minutes and then add it to the total quantity of 45% rice wine. Is this an adequate amount of time and do you practise this method?
