Does Ganoderma mushroom help the immune system?!

Does Ganoderma mushroom help the immune system?

I found a healthy coffee that contains Ganoderma murshroom Does anyone know of any research on this?

I take Ganoderma mushroom capsules daily and the reason was to help detoxify, it alkalines the body and you really can tell. At first i experienced detox symptoms so i believe they are very good.
They do support the immune system as well as protection from cancers.
I buy mine from DXN international they have a head office in the office tower in Church St. Paramatta.
They sell all the products there incl. coffee (i drink the mocha) and they'll give you all the info. you need.
