Hi there
I am in Western Australia and have come across two websites in Australia that I'm very interested in approaching for Reishi Mushrooms, even though I'm not particularly fond of edible mushrooms, I am willing to take the plunge for all of the benefits!
The first one I found has got me the most interested, as it is within West Australia, and seems to be 100%:-
Mushrooms for Optimal Health | Touchwood Mushrooms. The other is also in Australia and is
Australian Grown Reishi Mushroom - Forest Super Foods.
I have only just started investigating these products in the past hour or so and have been considering them because they are available within Australia and not only cost less than from overseas, but they are also quicker to obtain, AND hopefully as good as the overseas products.
