I have been taking this for 3 weeks, my BP dropped from 130+ / 85+ to under 120/78. I was recommended this by a friend whose mother had lung cancer, and it helped her through the radiation treatements.

Great immune enhancer

Posted by Reviewer2286916 on Jun 17, 2008

I was introduced to this product by an alternative MD who gave it to my 94-year old mother who had lymphoma at the time. I take it whenever I feel like I am getting a cold or if a feel a bit run down. I have not had a cold in three years! When buying this product make sure it is this particular formula.

Great Immune Builder

Posted by Reviewer1989577 on Jun 23, 2013

I have been taking Grifron Maitake 4X for 5-1/2 years. I recently had a cold for the first time in 5-1/2 years. I thought it was an allergy, so I didn't take the action I needed with Grifron Maitake. I have been able to ward off colds all this time with this product. I also give it to my husband who has an immune problem. This product is great, but you have to attend to any symptoms that resemble a cold immediately and continue taking it about every 8 hours for the first 24 hours. That's the secret to warding off sickness.
