Hi, I'm new to tincturing mushrooms however have finished different medicinal herbs for years. We use a couple of mushrooms in these Fxs such as Fu Ling (poria), Zhu Ling (polyporus) & Reishi for example & for simple water decoction of herbs we always boil them down to the required quantity, often four hundred ml for 2 day by day doses of 200ml, which means it doesn’t really matter how a lot water you start out with, however usually it’s 3 occasions the required final vol. I only take a couple of droppers a day, so you don’t really need much to last a yr. If you have any type of inquiries relating to where and the best ways to use manufacturer of shiitake mushroom extract powder for cosmetic Ingredients, you can contact us at our web site. However, due to the small dosages, often no more than 20ml per day, this isn't a problem for most people.
