It boosts immunity

Posted by 4884830627694950384 on Aug 22, 2016

I first purchased this for my Aunt who had a terrible chesty cough for months. Antibiotics did not fix it. About 10 days on the Grifron Maitake eradicated the cough completely. I noticed that this product has no kind of preservative in it so I contacted Mushroom Wisdom to ask the safe shelf life of this product, as bacteria levels can eventually build up to unsafe levels in products with no preservatives. No reply. I contacted them a second time. No reply. So I still do not know how long the bottle lasts before one should discard it, so I remove one star for poor customer service of the Mushroom Wisdom company.

Powerful Mushroom for Immune System!

Posted by Reviewer3232704 on Sep 16, 2011

Helpful company! Called the company directly for the proper dose & gave this to my cat who was fighting cancer. After the vet opened him up and closed him back up leaving the huge tumor in his abdomen, this helped him recover from the surgery. Amazing! Also he was born with a little birth defect that caused his eyes to shake back and forth, after two weeks of the Maitake it stopped. Amazing! As for the cancer we just found it too late, but we were so close to conquering it. Another vet gave him something to increase his appetite and it through him out of balance. No hard feelings we were all trying to help him. :) Just a side note: I took it too & noticed my breathing improved. For years I would wake up with a stuffy or clogged nose and it took it away.
