Jim asked what the lady with PD was taking in addition to the green algae? All I know is that first she went to another naturepath. He prescribed products from Standard Process Inc. You can only get them from a licensed person. But according to her, it was the blue green algae that gave her that extra push. They are from a company out of Klamath Falls Oregon. and harvested from a crystal clear lake in that region. We have done lots of alternative things. My husband calls me his "witch doctor" I feel we are doing something right, after over 12 years of Parkinson he is still putting in 14 to 16 hour days on our ranch. Came in last night at 11:30 and was up at 6:00 this morning. I really feel that alot of what we are doing has kept away many of the side effects that so many on the list are experiencing. I try lots of different things, continue with some and trash the rest. I feel that this is worth a try. According to the literature it contains nutrients in trace amounts and is naturally chelated. The natural nutrients include: Minterals, vitamins, chlorophyll, proteins, amino acids, and beta carotine. They test their products for toxins etc with every batch and freqently have a indepentent company do the testing. Nancy B
